Nutritional yeast is sold in bags, bulk or round containers as flakes or powder (either will work for the recipes in The Foodie Bar Way), at supermarkets like Sprout’s, as well as from online retailers and has a nutty/cheesy flavor. This is not to be confused with active yeast (for bread making) or brewer’s yeast (a byproduct of beer production). Store it at room temperature. This is a MUST HAVE ingredient for making Our Favorite Cheezie Sauce (incredible). Different brands have slightly different flavor profiles, so try different brands, (bulk section makes it easy to buy a small amount), and find the one that you enjoy the most.
