How to make your soup wonderful: Wild food soup stock

nettle soup stock

We’ve mentioned urban foragers and foodie extraordinaires Pascal Baudard and Mia Wasilevic before. They not only forage food, but go on to make really good stuff with it. One of their websites is Urban Outdoor Skills, and I like to go there to check out a section called the Food Lab, where they talk about food products they’re experimenting with, and give how-to’s.

A few months ago Erik brought home a beautiful bouquet of nettles. I decided to try one of the Food Lab projects that intrigued me — Wild Food Soup Stock Preserved with Salt. This is no more than a bunch of finely chopped vegetables, herbs and greens (wild or not) mixed with plenty of salt to preserve it.  I made mine with onion, celery, parsley and those nettles. It makes a strong, salty paste that keeps well in the fridge. My first jar is almost finished, and I’ve been using it for months. It still looks good.

Pascal says this is a traditional European method of making instant soup stock, but instead of using it as a stock by itself, I’ve been using it as a finishing touch at the end of cooking up a pot of something.  It really helps at that tricky moment when you’re standing over your soup pot, spoon in hand, asking yourself, What does this soup need? Somehow it improves the flavor in a subtle, magical way–and in the meantime, garnishes the soup with tiny bright confetti flecks of green. Note that this stuff is super-salty–so I hold back on the salt until I add this, and then add more if necessary.

Citified Parched Corn

I was thinking about trail food, and wishing for a portable snack which was not based on nuts and chocolate chips (though there’s nothing wrong with that!) or too sugary, like dried fruit or energy bars. Then I recalled parched corn.

Parched corn–dried corn which has been roasted–is one of those legendary Native American foods, like pemmican, which you hear about but don’t necessarily ever get to try. Parched corn is a lightweight, long-keeping, high-energy trail food. It can also be ground into flour and used in cooking. I have vague elementary school memories of claims that a warrior* could walk a whole day nourished on just a handful of parched corn.

(They did not mention that the warrior might be cranky at the end of the day–which I suspected might be the case. I’ve heard similar claims about Roman soldiers marching on handfuls of barley. Poor guys. But now that I’ve tried parched corn, I must admit that it is strangely filling. I managed to spoil my supper by doing too much tasting as I roasted the corn. So maybe the claim are real and–geek alert!– parched corn is our homegrown Lembas bread.)

Parched corn, being tasty and useful, was widely adopted by the Europeans who arrived here. So it was turned out to be the Official Snack Food of wagon trains and trappers and the like.

I went looking for a recipe and found my idea was hardly original. Preppers and outdoorstypes love their parched corn and there are plenty of recipes and tips out there. The only thing that I have to offer that is different is that this is a rather sissified, citified, consumerist version of parched corn.  And it is delicious. Chewy, sweet, a little salty… and most of all, corny.

How to Freeze Food in Canning Jars

Canning jars are the best way I know to avoid using plastic when freezing foods. You’ll want to use wide mouthed canning jars like the one above, that come in pint and half pint sizes. Don’t use jars with shoulders–these jars will break due to the expansion that happens when food is frozen.

Kerr and Ball jars are marked with a freeze fill line that’s about an inch below the rim. Don’t put food you intend to freeze above this line.

Avoiding plastic lids is more difficult. Two piece Ball lids have a BPA coating (which, I’ve heard that they are considering phasing out). I suppose you could use a BPA-free Tattler lid, though I haven’t tried them. For freezing I use food grade plastic lids sold by Ball. Food is not in contact with the lid, so I’m not too concerned about the plastic, though I understand that some people won’t agree. At least the lids are more easily reused than ziplock bags. It looks like Ball now has BPA free lids.

But jars won’t work for freezing a pork chop–see an interesting thread on Chowhound about this issue that Root Simple reader Peter Shirley alerted me to. Long story short: home freezing is a product of the post WWII era of plastics and refrigeration, so there’s not a lot of alternatives other than the jar option and less than optimal aluminum foil and heavy paper. It’s hard to beat the moisture retaining and freezer burn excluding properties of plastics. The plastic-free meat freezing alternative is to bring back the corner butcher shop and buy fresh.

Freezing Meat With Freezer Paper

A good question came in on Friday’s post about freezing fruits and vegetables about how to freeze meat products without using plastic bags. I don’t know of a way to avoid plastic with meat products, but you can use freezer paper instead of ziplock bags. The University of Georgia Extension Service has a handy info sheet on how to wrap meat with freezer paper: Freezing Animal Products.

Correction: an earlier version of this post was entitled “How to Freeze Meat Without Using Plastic.” I had forgotten that freezer paper is coated with plastic. You can use glass canning jars to freeze (just don’t use a jar with a shoulder). While jars are a great way to freeze soups and stews, they are not suitable for cuts of meat. If you are aware of a way to freeze cuts of meat without plastic, please leave a comment.

How To Freeze Fruits and Vegetables

Freezing foods is just about the most boring food preservation method. It’s also the easiest and best way to preserve nutrients. But, when it comes to freezing fresh vegetables from the garden there is one important step: blanching. Blanching slows down enzymatic activity that can deteriorate the quality of what you freeze. How much to blanch depends on the vegetable in question. Thankfully there’s a handy publication from Oregon State University, Freezing Fruits and Vegetables, that covers blanching times and many of the other particulars in freezing foods.

One thing not covered in that pamphlet is that some foods like berries, green beans, peas, diced onions, whole-kernel corn etc are more convenient to cook with if you can just pour them out of a freezer bag without having to break them out of a solid mass. To do this you’ll individually quick freeze IQF them. To IQF:

  1. Wash, blanch (veggies) and cool .
  2. Spread in one layer on a cookie sheet and place in the freezer for four to six hours.
  3. Pack in sealed containers or in freezer bags.
  4. Label with date to avoid freezer mystery bag phenomenon.

Now when the zombie apocalypse arrives and everything goes Beyond Thunderdome, freezing will not be the best option (unless, like Tina Turner, we figure out how to turn pig waste into propane to power our refrigerators). But I digress.
