These came from my Red Star Vegetarian Support Formula cookbook that uses their brand of nutritional yeast. Theirs is good but I use NOW brand, other flake nooch brands will work too. These are a delightful vegan treat to have with soups, vegan gravies, etc. Any kind of non-dairy milk will work-- just under 1 cup, but whole-wheat pastry flour is a must instead of regular whole-wheat flour.
