Fluffy Brown Rice

Combine rice, water, and acid medium (whey, etc.) in a large pot or saucepan.  Cover and let sit at room temperature for at least 7 hours.  When ready to cook it, bring to a boil, skim if needed, and reduce heat to the lowest possible setting.  Stir in salt and butter and cover tightly.  Cook for about 45 minutes without removing the lid.
