What is nutritional yeast flakes?

Nutritional yeast flakes are deactivated yeast, a yellow powder or flakes similar in appearance to cornmeal.

Found in the bulk sections of many health food stores and is popular with vegans/vegetarians to use in recipes for a creamy, nutty or cheesy taste.

Yeast flakes contain protein and Vitamin B12.

Make vegan cheese sauces, gravies, soups and popcorn with nutritional yeast flakes.

Where To Purchase Nutritional Yeast Flakes

Nutritional yeast flakes are sold in most health food stores or online on Amazon. This is what I like Sari Foods Nutritional Yeast Flakes.
