are amazingly delicious and healthy. Do some research, make some and see how you feel :)
Flax seeds seem to go for about $4.50-$5/lb. This is kinda pricey, putting them raw at about the price of gourmet chocolate bars or peanut butter. However, to make the crackers one adds a lot other less expensive ingredients- whatever culinary herbs you're growing, and in season vegetables. They are a wonderful way to utilize bumper crops of tomatoes, for instance.
This is how we made the crackers.
First, Mr. Mark Seimer and I ground some flax (and sesame and chia) seeds in the coffee grinder. Then added an equivalent volume of water, and stirred the bowlfull up with a spoon. The seeds soak up a lot of water, and become mucilagenous. It's this quality, among others, that make them so desirable for cracker making- it holds all the ingredients together. I swear, you bite into one of these crackers and it doesn't break except where your teeth pleasingly crunch. There were a lot of times this afternoon when I'd bite down and be left with a crescent moon of cracker! They're also high in fiber, which might have something to do with the flax's binding ability.
Leave the ground flax to soak awhile, and make your veggie smoothie. One can add nuts, oils, and spices. We added curry powder, cayanne, three roma tomatoes, a bit of greens (kale/lettuce/chard), purple cabbage, half a small onion and 4 cloves of garlic. Garlic seemed to be important for flavoring, as was the sea salt.
Now once you've got your smoothie, mix it into the soaked flax. This you spread onto your dehydrator's pan, or if you live somewhere dry and sunny, perhaps you'll rig up a way to do it outdoors. The cracker will be in the box for 10-12 hours, then Mark will flip it over and do it again on the other side. For moister, breadier crackers you can shorten this time. However, Mark is experimenting with shelf life for these fabulous raw food staple. Hit up google and see how other people are doing it.
