Instant Yeast Overview

Instant yeast is a fast-acting form of baker’s yeast designed to be mixed directly into dry ingredients. Like all yeast, it is carbohydrate-based and requires fermentable sugars to function, making it a high-carb ingredient by classification and unsuitable for keto or diabetic-friendly baking.
