How to Substitute Buttermilk Successfully
Substituting ingredients requires understanding their chemical properties. For example, replacing fats like butter requires matching fat and water content, while replacing leaveners like baking soda requires balancing acidity.
Always measure substitutions carefully. When swapping liquid for dry options, adjust other recipe liquids to maintain the original hydration levels of the batter or dough.
Exact measurements make substitutions seamless.
