What is nutritional yeast?
Of all the ingredients, I use in my recipes, nutritional yeast garners the most questions. It is a deactivated yeast product, which is grown, harvested, washed, and then dried with heat that deactivates or “kills” it. That means it does not have the leavening ability of baker’s yeast. Therefore, it is a purely vegan food additive. It is a great source of vitamin B12, and does not contain any whey or animal products. It is low in fat, and gluten free.
The primary reason most people use nutritional yeast is for its amazing flavor. It has been described as cheesy, nutty, savory, and umami. It can enhance soups, gravies, and when you use larger amounts it creates great cheese sauces. If you use an egg substitute, just a small amount can make those eggs taste cheesy, and eggy.
And one more thing… IT DOES NOT CONTAIN ANY MSG.
And now you know the rest of the story.
