Grandma's Grains

Grandma's Grain Recipe

If you can't find one of the ingredients, don't be discouraged. Simply substitute more of whatever you do have - more rice, millet, etc.

1 cup long grain brown rice (I use Lundberg's)
1 cup millet
3 handfuls of whole barley
3 handfuls of whole oats (groats)
1 handful of red rice, wild rice, or a mixture of wild type rices
2 teaspoons salt

Mix all grains together, rinse, drain, and put in a large thick-bottomed pot. Stir in the salt. Cover with water up to your knuckle - about two inches above the grains. Bring to a boil, then turn down flame as low as it will go. Cook uncovered (simmering) until all water is gone, about thirty-five minutes. If you overshot the amount of water you added and your grains cook before the water absorbs entirely, strain off the extra water.

This makes a big pot of mixed grains. Plenty for a family of four to use over the course of a week.
Dan's note: it's true. This is a ton. I made a half recipe, and it's enough to last me forever.
