Scouting the Wild Asparagus

November 6, 2009

I’ve been building up a patch of asparagus in the backyard, but lately I’ve been seeing it growing wild just about every time I take the highway.  I started out taking mental notes of where each patch was, but I’ve given up—it’s all over the place, so I’m assuming I’ll be able to find some come spring.
This is an ideal time to locate a patch, though.  In the spring, the sprouts are just a few inches tall and impossible to find without coming within a few feet of it.  In the summer, when it has bushed out, asparagus blends into the other greenery.  In autumn, however, it turns a particular hue that stands out from the bleached-out stalks of the other roadside plants.  It’s hard to describe, and doesn’t really photograph well, but it’s a bit yellower than the straw-colored grasses.  It also has what Euell Gibbons (author of Stalking the Wild Asparagus, the inspiration for this article’s title) calls a “Christmas tree shape”—kind of a lacy pyramid.  If you don’t know of anyone who grows asparagus who can give you a peek at the full-grown plant, I’d seek it out.  You might even be able to convince a farmer’s market vendor to let you take a look at their fields.  Once you get a look at it, it’ll be easy to spot, even from some distance.  I’m hoping that the bushes are as easy to identify in the spring, after they’ve been under the snow for a few months.
Lately, I’ve been seeing it along highways, with one patch growing literally at the intersection of the two biggest highways on this side of the state.  In the past, I’ve found it growing along rivers, and friends have told me of patches near the Lake Michigan shores, but the highway side is the best place to start looking.
I’ll put up a proper post once I’ve found, picked, and prepared some in season, but I’ve been seeing it all over and thought I’d spur my regular readers to start seeking it out.

Black Walnuts: Tedious but Delicious

September 21, 2009

Foraging will always take more time than preparing store-bought food, but black walnuts may be the most time-consuming wild food I’ve tried.  Finding and collecting them can go quickly, but the prep work (and the eventual yield) give walnuts one of the highest time-to-food value ratios.  For me, it’s worth it, but you might want to try these out on a small scale before you commit to bushels and bushels of walnuts.

Finding Walnuts

I’ll find walnuts while hiking now and then, but when I’m looking to harvest them, I’ll drive through some of the older neighborhoods in town.  Black walnuts are generally despised as shade trees, but a few people still have them in their yards.  You can usually see their driveways and patios littered with the blackened husks, and all but the most paranoid neighbors would love to have you gather a bushel or two of nuts.  I’ve also had good luck asking on local online message boards.  The greasy, round, rotting walnuts can pose a serious safety risk, so a lot of people are grateful to have someone come over and pick them up.

Harvesting Walnuts

Harvesting is easy.  I bring a bucket, bushel, or basket and start picking them up off the ground.  I’ve never tried to pull them off the tree, as they generally fall off when they get ripe.  I try to be selective, and just get the freshly-fallen, completely green fruits.

Preparing Walnuts

This is where it gets difficult.  First, you need to remove the husks.  The walnut juice will stain your clothes and skin, so wear gloves and grubby clothes.

I start with a patio stone and a sturdy pair of boots, grinding each walnut under the heel until the green part falls off and I’m left with the familiar-looking nut.  I’ve read accounts of people spreading them over the driveway and driving over them, but I find the monotonous and violent boot method soothing.  It’s important to get the husks off as soon as possible, as they begin to decompose, which causes the nuts to spoil.  The husks will be really wormy.  The grubs are disgusting but won’t affect the nut.

Once they are husked, the nuts need to be rinsed.  Dump them in a bucket of water.  I’ve read (but not confirmed) that the ones that float are spoiled.  I discard them, but only after making sure I’ve removed all of the husk–every so often, a bit of the especially-bouyant husk will be holding up a nut that would otherwise sink.

After they’ve been husked, I hang them in a mesh basket from the clothesline.  Squirrels will seek them out extremely aggressively, so be sure they’re secure.  Once they’re dry, I put the nuts in the freezer, or in a cool place if the freezer’s full–The nutmeat is really oily, so low temperatures keep it from going rancid.

The nuts need to be broken up to remove the meat, and black walnuts are far harder than the commercial (English) version.  A nutcracker won’t do it, but a hammer will.  A solid strike at the pointy end will split it in two, but they’ll need to be busted into quarters or smaller to get the nuts out.  If available, a bench vise works way better than a hammer.  I put them in so that the seam of the nut is perpendicular to the face of the vise and crank down until it cracks.  I’ll crack nuts until the vise handle starts to hurt my palm, then put it all back in the freezer until I want to get back into it.

When they’re cracked, the last step is getting the meat out.  If you’ve cracked the nuts into the quarters, you should be able to pull out fairly big chunks of nutmeat with a nut pick, awl, or toothpick.  I put all of the meat in a jar and put it in the freezer.

Eating Walnuts

Black walnuts have a much stronger flavor than commerical walnuts, which makes them ideal for baked goods.  I treat them like a precious commodity, having gone through a lot of work to procure them, but they work well in zuchinni bread, carrot muffins, and brownies.  They are better the sooner you use them, so be generous.  I love the flavor, and they are one of the few nuts available that are locally grown, but they are an aquired taste.  My wife tolerates them, and others don’t like them at all.  As I said, try out a few before investing the time.

Winter Greens, Part II: The Cold Frame

March 22, 2009

This entry is a follow-up to my article on sprouts several weeks ago.

I planned on being able to post digital pictures before I wrote this, but that’s not happening.  In addition to sprouting various seeds, some home-grown and others from the store, I add fresh local vegetables to my winter diet through the use of a cold-frame.  I have had less than spectacular results, and a few meteorological mishaps, but the idea is worth sharing.

In my last entry, I gave a plan for an insulated straw-bale cold frame.  This year, I didn’t get enough bales before winter, so I used an alternate design–a variation on a hoop house.  I picked up about 75 ‘ of concrete reinforcing mesh–sort of an industrial-strength chicken wire with 6″ holes–to make tomato cages and a compost bin.  With the 15 or so feet I had left over, I made two sections that arced into a half-circle shape, about as wide as one of the beds in my garden.  Each section was cut to leave 6″ lengths of wire sticking out on the ends, which I stuck into the ground to secure the frame.  This left me with a wire tunnel, about 5 feet long, 4 feet wide, and 3 feet tall.  I was able to get some greenhouse-grade plastic (leftovers from a local greenhouse) to cover my frame, and weighed down the edges with some fist-sized rocks.  This left me with a miniature version of the full-sized greenhouses you’d see at a commercial-scale nursery.

The cold frame collects and retains solar energy, resulting in, well, a “greenhouse effect” that keeps the plants within at a much warmer temperature than the outside air.  Though this would only add a week or two to the life of warm weather plants, like peppers or tomatoes, it can keep cool-weather plants alive through all but the coldest Michigan winters.

Fall and Spring Planting in a Cold Frame

I stuck with cool-season greens in the fall, such as leaf lettuce, bok choy, and spinach, planted in the early fall or transplanted a little later.  These go more or less dormant when the weather gets cold, but the cold frame keeps them in a harvestable state through most of winter.  There isn’t a lot of growth, so your stock dwindles as spring approaches, but it’s a great way to keep some fresh and local food on the table all winter.  With no disrespect to the other two winter-long green vegetables, it’s way more interesting than kale, and far more versatile than brussel sprouts.

In spring, the cold frame is more of a head-start than a long-term plan.  Around the time I’m planting pea seeds, I pull out the rest of the winter greens from the cold frame (there’s usually not much left, and what’s left is starting to toughen up and flower), and plant a new crop.  This year, it was spinach, bok choy, leaf lettuce, and very early carrots.  The additional heat and humidity from the enclosed cold frame will give them several weeks of extra growing time before the open-air garden is ready to be planted.  I’ve sited the cold frame in the place I’m putting this year’s peppers, which won’t be planted until early summer, so most of these plants will have a chance to mature before the peppers go in.  I’ve considered putting the peppers in a few weeks before the last frost, hoping that the cold frame would give them the shelter and warmth they would need, but I don’t think it’s worth the risk.  I’m not sure how cold it can get in a cold frame, particularly at night.

Cold Frame Problems

Weather rarely cooperates with cold frame construction.  I’ve had my plastic sheeting blown off completely, despite weighing down the edges and clipping the plastic to the frame.  I’ve also had the entire thing collapse under the weight of snow and ice, crushing the leafy plants underneath.  Also, since the plastic sheeting is impermeable to rain, it can get desert-dry inside of a cold frame when all the ground moisture is frozen.

Access to vegetables is another problem.  With rocks weighing down the edges, water sometimes pools and freezes, making it hard to lift the plastic sheeting and reach in to harvest.  The 6″ access holes are also an obstacle.  I’ve adopted a “mass harvest” mentality, getting a week’s worth of greens in one go, just to simplify things.

Once spring starts to warm up, it can get very hot inside a greenhouse.  Think of a car parked in the sun with the windows up–opening up the cold frame on those warm, sunny days is a necessary inconvenience.

Weeds that are growing in the space where you’ve set up your cold frame are also able to take advantage of the microclimate, so they often spread throughout the winter.  Finally, keeping a bed in production all year takes a lot out of the soil, so your cold-frame bed should be refreshed with compost or fertilizer more often than others.

Possible Improvements

I’ve considered a number of options that I haven’t followed through on yet.  The first–instead of using weights to hold down the plastic, I’ve seen cold frames with trenches dug along their edges, with the edge of the plastic sheet buried under a few inches of soil.  This would hold it down a lot better, but would make it much harder to get into the cold frame.

Another modification would be to put it in so that it straddled two beds, with a path down the center.  I’d have to crawl in from the end (the taller a cold frame is, the less efficient it is, as heat rises away from the plants), but I wouldn’t have to reach, and I’d be able to bury the edges as mentioned above.

I’ve saved up a bunch of dark-colored laundry soap jugs, which I intend to fill with water and use as heat collectors.  The dark colors will absorb solar heat through the day, then release it at night.  Each jug takes up valuable square footage in the cold frame, though.

I may use a few stakes next year to reinforce the wire framework–I’ve never had a collapse before, but this year’s heavy snowfall brought the whole cold frame down.  It’s an easy enough fix, and I could have saved a few plants.

So far, using a cold frame has been more art than science, but it has kept in in the garden throughout the winter, and kept me out of the produce section of the grocery store for several weeks beyond the end of my garden’s regular season.  I’ll be building another straw-bale frame next year, provided I can round up enough free straw bales, but I’ll build another wire-frame hoop house as well, just to see if I can do any better.

Jerusalem Artichoke: A Forager’s Failure

November 10, 2008

I’ve been looking for a source for Jerusalem Artichokes for some time.  They grow profusely (to the point that they aren’t recommended in small gardens, where they take over), respond to harvesting with exuberant regrowth, and they serve as a starch, which sounded good to a forager growing sick of steamed greens.  This summer, I thought I had hit the jackpot.  In a scrubby little strip of woods near my house, the path through the middle is lined with plants that bear a convincing similarity to the Jerusalem Artichokes in my field guides–yellow, sunflowerish blooms, hairy, spear-shaped leaves, and thick, tall growth.

Exercising a gardener’s patience, I waited months until our first hard frost, which withers the topgrowth and sweetens the roots.  Using a trowel (I thought hauling a shovel in would look a little suspicious), I traced one of the now-brown stalks down to the earth and dug in, expecting to pull up a thin, sweet-potato sized tuber.  At the end of my stalk, there was a woody root about the size of a golf pencil.

I can’t say if I completely botched the ID, or if this just isn’t a very productive variety.  I’ll be looking through a few wildflower books to see if I can find anything else that fits this description.  I was able to salve my disappointment with some home-grown turnips and butternut squash, with grilled pork loin.  I’ll be thawing some of the wild applesauce to mix in with the leftover squash tomorrow.  After spending the afternoon tossing a compost pile (it was well over my head before I rearranged it), cleaning up some perrenial beds and the herb garden, and stealing bagged leaves from my neighbor’s curbs, I’m ready for winter.

Wild Apples: Foraging the Familiar

October 25, 2008

It’s been a long while since my last entry, in part because of my non-weblog obligations, and in part because I was hoping to fix the digital camera upon which I’d saved the pictures of my apple harvest.  The camera is done for, but fortunately, my loyal readers should know what an apple looks like.

Finding Apples
Michigan is apple country, so it’s not hard to find a wild apple tree.  Keeping an eye on the highwayside while driving should turn up a few apple trees, and a single tree should supply enough apples for the beginning forager’s needs.  It’s easiest to wait until the trees have fruited to identify them.

I found my tree growing in the middle of the grounds of an apartment complex behind the neighborhood Blockbuster.  To be honest, I think it’s just a Golden Delicious that has gone feral.

Harvesting Apples

I pulled an apple off to taste-test for ripeness.  When they were ready to go, I pulled them off until my bushel basket was full.  It’s times like these I wonder if I need to stick to my finding-harvesting-preparing-eating format for foraged food entries.

Preparing Apples
I put a little effort into picking apples that weren’t particularly wormy, but they all were a little more damaged than I’d enjoy eating out-of-hand.  After chopping one up, with the intention of making a cobbler or something, I discovered that making anything but applesauce wasn’t really worth the effort—by the time the apple was peeled (a pain with such small apples) and cored, there just wasn’t a lot left.

When I’ve made applesauce in the past, using commercially-produced apples, I peeled and cored them, simmered them over the stove, then mashed the cooked apples, but that didn’t work with whole apples.  After several frustrating attempts to make do with the implements I had in my kitchen—at one time I ran the apples through a meat grinder, then tried to push them through a colander—I swallowed my pride and purchased a Foley food mill.  It made all the difference, and I’ve used it for processing tomatoes since then.  It’s a human-powered technological marvel, and I’d recommend you pick one up if you find it used—you’ll find uses for it.  By the end of my bushel full of tiny wild apples, I was roughly chopping the apples, cooking them down a bit, then running them through the food mill with the fine plate on—the coarse plate let the seeds through.

Eating Apples

I tried a few of these apples eaten out-of-hand, and they tasted a lot like Golden Delicious, but they were too small and insect-bitten to be a pleasurable hand fruit.  I haven’t come up with a better way to eat them than in applesauce form.  I’ve been adding applesauce to cooked garden squash, though, and it’s a great way to spice up squash, right about when you’re getting sick of it.
