How do I substitute Isinglass in baking?

In baking, always choose a plant substitute that mimics the functional role (binding, leavening, moisture, or fat). For binding, use flax eggs or chia seeds; for whipping or leavening, use aquafaba; for rich moisture, use plant creams or purees.

Will vegan substitutes change the taste of my recipe?

Most culinary swaps (like aquafaba, neutral plant oils, or unflavored soy milk) are neutral and undetectable once baked or simmered. Specialized ingredients like cashew cream add rich velvety mouthfeel without overpowering flavors.
