You’ve got three basic options: freezing, dehydrating, or canning. More ambitious folks can try fermenting, like I did with my bumper crop of bok choi last year. But let’s stick with the basics here.

Freezing Greens

This is the easiest, and probably the best, solution. It’s very, very easy to freeze greens. You just blanch them, cool them in an ice bath, and freeze. I’ve got step-by-step instructions and photos here. Assuming you’ve got a good freezer, these will keep very well for a year. We used ours all winter in soups, stews, pastas, dips, and even just sauteed with garlic. They shrink dramatically when blanched—plan on about a pound of fresh greens to make about two cups.

For most people, this is the way to go. If, however, you have limited freezer space, you live in an area that experiences frequent power outages, or are planning for a future without electricity, you need other options. Alas, they’re not great. But, you asked, so here goes.

Dehydrating Greens

Are you one of those people who likes to sprinkle seaweed flakes over your rice bowl at the local health food store? Then you might like this. Steam your greens just until they’re wilted. Transfer them to dehydrator trays and dry at a low temperature (say, 110ºF) just until they’re crispy. You’ll want to keep an eye on them—within two hours, mine looked like this:

Now what, you may ask, would you do with dehydrated turnip greens? That’s an excellent question. I rehydrated some with a little bit of room temperature water, and they looked pretty good. The problem was that they had no perceptible taste. In the end, I crumbled them up and stuck them in a spice jar:

I sprinkled an entire leaf’s worth of flakes over a bowl of roasted potatoes and couldn’t tell they were there. I suspect that they’re still fairly nutritious, though, so maybe this isn’t such a bad way to incorporate hearty greens into your diet. I guess.

Canning Greens

The things I do for science.

Yes, it is possible to can hearty greens. It requires a pressure cooker and a processing time of 1 hour, 10 minutes for pints and 1 hour, 30 minutes for quarts. Yes, you read that right. And after you’ve subjected these poor, innocent vegetables to 240ºF to more than an hour, you get this appetizing product:

(And that’s the glamor shot.)

The nutritional value of all of this is questionable. They taste about like you would expect them to. If, however, you have absolutely no other options and feel strongly about having a pantry full of shelf-stable vegetables, this technique will serve you well. But Lordy, do they smell bad. Here’s how you do it.

1) Bring about 3 quarts of water to a boil. You need 2 quarts for the pressure canner, plus some extra to pour over the greens.
2) Steam the greens until wilted. Cut them into manageable pieces.

3) Stuff the greens into canning jars. Add 1/2 t. salt per jar (optional) and cover with boiling water, leaving 1″ headspace. Don’t forget to remove the air bubbles. Adjust two-piece lids.
4) Transfer the jars to a rack on a pressure canner. Pour in 2 quarts of boiling water. Lock the lid into place, but do not place the regulator on the steam vent. Turn on the heat and exhaust steam from the vent for 10 minutes. Then place the regulator on the steam vent and bring the canner to 10 pounds of pressure. Start timing once the regulator starts rocking—70 minutes for pints, 90 minutes for quarts. (If this is confusing, see the step-by-step directions, with pictures, in this post.)
5) Turn off the heat and let the pressure drop of its own accord. When the pressure has dropped, remove the regulator. Now open all your windows. After waiting a few more minutes, open the lid away from your body. The pungent aroma of overcooked turnip greens will fill your house, and you’ll have all the shelf-stable greens you want. Plan on 2 to 5 pounds per pint, depending on the kind of greens involved. Um, yum?

Other ideas?

My favorite strawberry farm, Gaventa’s, no longer offers U-pick. Waaaah. My next favorite strawberry farm, Mood’s, apparently isn’t offering strawberries this year, but plans to open for other fruit picking in mid-June. That left Johnson’s, a weirdly tourist-y place in Medford that I don’t particularly recommend as a “farm experience” (enforced hayrides = bad, in my book), but the price was right ($1.75/pound for more than 10 pounds) and the berries were DELICIOUS. But here’s the kicker: they wanted $4.95 for pick-your-own cherries. Um, no.

For that, we headed over to Rowand’s Farm in Glassboro. Now this is a U-pick I can live with. The proprietors sit in lawn chairs and hand you plastic buckets. Sweet cherries are $1.65/pound. They also have strawberries, but I can’t vouch for them, having already gorged myself at Johnson’s. But there’s a catch: they’re closed on Saturdays.

Once you bring all that fruit home, then you have to do something with it. Some options and recommendations from last year’s blog:

Freeze it, individually (not particularly recommended, but convenient) or in sugar
Make endless jars of jam, including my favorite, cherry raspberry
Can it with rhubarb
Combine it with lemons for a marmalade
Stash it in syrup
Dehydrate it

Julia over at What Julia Ate highly recommends drowning fruit in alcohol and straining the remains to make liqueur. This is a new one for me, so no results yet. But I’ll keep you posted.

Happy picking and preserving!

On a whim, I cut one up and stuck it in the dehydrator. I cut them into 1/3″ strips and dried them at 105°F overnight. After 15 hours, about half of them were done; the other half needed somewhere between 4 to 6 additional hours. The flavor is a little odd. I sort of like them, but my husband thinks they taste like cardboard….coral cardboard. Some foods just don’t dehydrate well on their own—my attempts at strawberries and raspberries were equally weird. If I were to do it again, I think I’d blanch them in a sugar syrup first, and maybe dunk them in coconut. Because, you know, if you’re going to fall off the local foods wagon, why not go all the way?

I do love the idea of dried papaya. Any suggestions on how to make it better?

So let’s talk about it.

First, it’s true that, traditionally, food preservation was the province of people who grew their own food. Canning and freezing have long been the default choices of cash-poor farmers with lots of land and time on their hands. This description no longer fits most people who can, but it remains true that the cheapest way to preserve food is to grow it yourself.

Unless you’re living on a small-scale organic farm, though, this isn’t helpful advice. Fortunately, there are other options for city and suburban folks. In order of frugality, your best options are:

1) Pick your own. Prices at Mood’s, my favorite U-pick in South Jersey, range from $0.85 for peaches to $1.15 for blueberries. Hard to beat, but you do need time. And a car.

2) Buy seconds. “Seconds” are fruits or vegetables that aren’t quite perfect. You have to be careful—sometimes seconds are actively gross. Mostly, though, they’re perfectly serviceable. This photograph shows what someone at my local farmer’s market sold me when I asked her for $20 worth of seconds. She gave me about 57 pounds of slightly cracked (look carefully at the bowl on the left) but otherwise beautiful tomatoes—a steal at about $.40 a pound. If you don’t see any on display, ask. Often a farmer will have bushels of seconds stashed until a table or in a truck, just waiting for someone to ask for them. Other tips: show up early (beat the other canners!) and build a relationship.

3) Buy in bulk. If seconds aren’t an option, at least ask for a discount. To your left, check out the 50 ears of corn I lugged home last weekend. Ordinarily, corn sells at our market for the premium of $0.50 an ear. For a farm girl, this is borderline extortion. So, I simply asked: how much of a discount would you give me for 50 ears? The price dropped to $0.40/ear. Still pricey, but 20% less than advertised (and, incidentally, cheaper than at my grocery store). You can improve your odds by showing up toward the end of the market, especially on rainy days. Look around for whoever has lots of produce left, and make them an offer.

And remember, you don’t need to invest in fancy equipment. If you’ve already got a chest freezer, you’ll only need to invest in a solid stash of freezer bags. If you’d rather can, Mason jars and lids are all you’ll need. Once you’ve bought the jars and rings, you can reuse them indefinitely. You do need to buy new lids every time, but that will only put you back about $2 per dozen lids.

Now, what did I do with my 57 pounds of tomatoes and 50 ears of corn? A dozen pints of canned tomatoes, 9 pints of tomato sauce, 3 pints of roasted tomatoes, 6 half-pints and one pint of roasted tomato salsa, 6 pints of tomato-pepper salsa, 7 pints of corn relish, and about 15 quart bags of corn for the freezer. Not bad for $41.

Why do I dehydrate tomatoes? So many reasons, my friends! First, they make your house smell wonderful. They keep for up to a year and make wonderful snacks. You can use them in pizza, pasta, ravioli, and soups. And, perhaps most importantly, it’s soooo easy. Just cut them up, toss them on the dehydrator, and let them cook overnight. Mmmm. Tomato candy.
