Will substitutions always work 1-for-1?

Rarely. Baking is chemistry — swapping butter for oil changes texture (less chew), eggs for applesauce adds moisture (denser cake), baking soda for baking powder changes acidity balance (can taste metallic without tweaks). The tool lists trade-offs per swap; follow them and accept small differences.

What's the best all-purpose egg substitute for baking?

For binding: flax egg (1 tbsp ground flax + 3 tbsp water, rest 5 min) or chia egg. For leavening (cakes, cookies): 1/4 cup unsweetened applesauce or mashed banana. For structure + lift (meringue, macarons): aquafaba (3 tbsp chickpea liquid). Each suits different recipes — check the notes per swap.

Can I substitute baking soda for baking powder or vice versa?

Not directly. Baking soda needs an acid (buttermilk, yogurt, lemon juice, molasses) to activate. Baking powder is soda + acid + starch pre-mixed. Rule: 1 tsp baking powder = 1/4 tsp baking soda + 1/2 tsp cream of tartar + 1/2 tsp cornstarch. Reverse only works if your recipe already has acid.
