Eno, which is a brand name for a combination of sodium bicarbonate (baking soda) and citric acid, is typically used as a leavening agent in recipes for quick breads, biscuits, and some Indian snacks. However, it is not commonly used as the sole leavening agent in cake recipes.
Cakes generally require a more precise balance of ingredients, including baking powder, to ensure proper rise, texture, and structure. While Eno can provide some leavening effect, it may not yield the same results as using the recommended leavening agents specifically designed for cake recipes.
For best results, it is generally recommended to follow the recipe instructions and use the specified leavening agents, such as baking powder or a combination of baking powder and baking soda, as they are formulated to produce the desired outcome in cakes. Substituting Eno for these ingredients may result in an unpredictable texture or flavor.
If you're looking for an alternative to leavening agents like baking powder, it's best to explore other options that are commonly used in cake recipes, such as cream of tartar combined with baking soda. However, it's always a good idea to consult a trusted cake recipe or a baking expert for specific recommendations and guidance.
