Primitive Grain Storage Technique

Screen Shot 2013-11-02 at 11.17.50 AM

When thinking about technology, I like to play with the idea of what is the absolute minimum you need to get the job done.  This may be because I’m not very handy at building things, but yet have survivalist tendencies. So while I’m pretty sure I’ll never actually have any need for these skills, it’s fun to think about how I’d get by in a DIY world.

So I was delighted when I ran across this minimalist grain storage technique on the BBC documentary series, A History of Celtic Britain (2011), hosted by Neil Oliver of the Delicious Scottish Accent. (I am watching it on YouTube. Fingers crossed the BBC will not take it down before I finish it!)  I love this technique because while it is simple, it is far from stupid.

The technique is described by the Dave Freeman of the Butser Ancient Farm in Hampshire, where they’ve been experimenting with grain storage iron-age style (c. 400 BCE.).  Turns out all you need to do is dig a pit in the soil. The pits they dug are circular, and look to be 2 or 3 feet in diameter, and maybe 3 or 4 feet deep.

So you may ask, how can you pour grain into a hole in the ground and expect it to keep? The secret is a clay cap on the top. In the screen grab below you can see the cap and some feet for scale:

If you go to YouTube,  you can watch this sequence starting around 52:36, but what Freemen says is that when the grain goes in the pit and is sealed with a clay cap, the clay blocks out moisture, air and light. Moisture is still available at the sides and bottom of the pit, of course, especially as they are in green Hampshire.

The grain touching the sides of the pit sucks the moisture out of the soil at the edges, and uses it to attempt to germinate. The germination process sucks up oxygen and releases carbon dioxide, effectively clearing the chamber of oxygen. At that point, as Neil puts it, “Time stops.” Nothing can grow, nothing changes. The grain cache keeps for at least a year, perhaps two years, and provided a very handy safety backup for hard working iron age farmers. And some very basic appropriate tech for modern armchair survivalists to ponder.

Gourmet Foraging and Advanced Acorn Processing

acorns

It’s acorn season in Southern California. I’ve long been interested in acorns, knowing that they were the staple food of the native people who lived here, and I’ve gathered and processed them before. However, once I have the acorn meal, I’ve never known exactly what to do with it. It’s highly nutritious, but I thought (wrongly!) that it was somewhat bland, and all I could do was incorporate acorn meal into baked goods. This weekend, however, I’ve had my eyes opened to the possibilities, thanks to Pascal Baudar and Mia Wasilevich.

Pascal and Mia putting out a spread: acorn sliders, acorn and tapioca pudding, red cabbage and red onion slaw with wild juniper berries, chocolate truffles infused with white sage and dusted with dehydrated raspberry powder, plum membrillo and beer hopped with yarrow. We were there to learn about acorns, but they fed us well!

Pascal and Mia are high caliber foragers and foodies.  Check out their sites, Urban Outdoor Skills and Transitional Gastronomy, and if you live in the Los Angeles area, you’ll definitely want to experience their forages and food workshops. Their Meetup groups are The Los Angeles Wild Food and Self-Reliance Group and Foraging Foodies LA.

It’s rare to find folks who combine deep food know-how with a love of wild foods. Too often wild foods are considered mere survival foods. Pascal and Mia are using them to develop a uniquely Californian cuisine. Just check out this gallery on Transitional Gastronomy to get a quick picture of what I’m talking about.

On Sunday, Erik and I attended their acorn processing workshop, where we learned some valuable tips regarding acorn processing, and were privileged to eat the finest vegetarian burgers we’ve ever tasted — sliders made with acorns.

acorn sliders

I’ve downed a lot of veggie burgers in my time, and I’ve come to think of them mostly as excuse to eat bread and condiments. I’ve never had a veggie burger good enough to eat on its own. The acorn burgers they treated us to were not just “good for veggie” but some of the tastiest food I’ve ever encountered.

It turns out that acorns have umami qualities, that savoriness that characterizes meat and mushrooms, along with a delicate sweetness. You just need to know how to bring it out.

Mia did say that acorns have unique qualities in how they hold and absorb moisture, so she’s been learning how to handle them. Like any new food, it takes a while to learn the ways of acorns, but it’s worth it.

Here’s a recipe from Mia’s Transitional Gastronomy site for acorn timbales. If you serve these on a bun, instead of in a pool of (amazing looking!) nettle veloute sauce, you will have the acorn burger I experienced this weekend.  Do be sure to note the part where she asks you to refrigerate the mix before cooking. She told us that if the mix doesn’t have time to set up, the patties will fall apart. The recipe doesn’t specify how long to chill, but I believe she said overnight. (You could also make a log of the mix and freeze it for later, like cookies.)

I’m going to forage some acorns of my own this week and see if I can replicate those sliders. In the meanwhile, after the jump  I’m going to share some processing tips that I picked up.

Let us know if any of you process acorns,  and if you have any tips or recipes!

The Upside Down Fire

This is how I make a campfire fire now. I used to use the teepee method, or some half-assed rendition of the teepee method, and I often had trouble with such fires. They required babying, rebuilding, etc., and they burned fast. This fire is built in the opposite direction: heavy stuff on the bottom, lighter stuff on top, tinder on the very top. Basically, the finished product looks like a bird’s nest sitting on a log cabin.

This style of fire is great because it takes care of itself–build it, light it, and get on with your other chores. It lasts a long time too, as it makes very efficient use of the wood. I’ve done this many times, and it works like a charm.

The video above is a little shaky, but the technique is clear. He’s building a big campground fire in a fire ring. It’s not necessary to use so much wood–the technique scales. Here’s a link to another video showing the same method with smaller sticks and a more bushcraft-y technique.I’d recommend watching both.

The only thing I’d add to the technique in the video above is that I would lay down a larger layer of thin sticks (the 1″-2″ diameter stuff) on top of the big logs. Somehow he pulls it off with remarkably little small stuff. I found that if I didn’t have a good supply of twigs and small branches on top, the big logs in the under layers didn’t catch fire fully.

In video #2 the fellow builds a complicated teepee structure on top with his twigs. I don’t think that’s necessary, either. I mean, it’s okay, but it seems like work. You can just pile lots of little stuff on top any which way and light it.

It’s like Goldilocks. I think the first guy has too little tinder, the second guy, too much. But to each, his own. You’ll find your own way–and you’ll love this fire.

ETA: I forgot to mention that a Vaseline soaked cotton ball or a lint firestarter or some pieces of fatwood or something similar can really help foolproof the fire. Just tuck the firestarter under the small stuff. Not at all necessary, but helpful if you’re a beginner, or if conditions are bad.
