A lot of this thread has been about oatmeal, but we have overlooked a related product - acorns and acorn mush. Acorns were the staple for prehistoric Californians, who ate it morning, noon, and night. There are a lot of ornamental acorns in my neighborhood and every year the acorns drop, remaining unharvested.

The problem is, we have lost the technology for leaching the tannins out (well,maybe Blast knows), and that is extremely necessary. When you do that, I understand you have something that tastes like - oatmeal!

But it is dirt cheap. After all, acorns do grow on trees.....
