So. I bought a coffee mill (Cuisinart DBM-8 Supreme Grind Automatic Burr Mill - http://www.amazon.com/gp/product/B000...)
i dumped a box of quinoa in, then poured it back in, milling it three times altogether. And used it to bake a batch of banana cranberry muffins. Regular recipe. K P baking soda.
Astonishing. Just astonishing. They will be lunch tomorrow and I will make more to take on chol hamoed tiyulim. and probably for children's breakfasts. The only reason not to do this is that it doesn't taste at all like Pesach.
