Chemical leavener containing baking soda, acid, and starch. Double-acting.
Baking powder is the easier all-purpose leavener because it carries its own acid. It is usually the safer choice when a recipe does not already contain a clear acid source.
Use 1/4 tsp baking soda + 1/2 tsp cream of tartar per 1 tsp baking powder
This is essentially homemade baking powder. Single-acting only.

Cool, dry place. Loses potency after 6-12 months. Test by adding to hot water.
Double-acting: first rise from acid + soda when wet, second rise from heat-activated acid in the oven. Self-contained system (doesn't need recipe acid).
Baking powder helps create an even rise without relying on dairy or fruit acidity to do the job.
It gives a more forgiving lift than baking soda alone, especially when the batter is neutral and not highly acidic.
Double-acting baking powder helps keep rise going in the oven after the dough is mixed and cut.
Baseline reference: 1 cup baking powder = 184g. In real kitchens, a practical range is usually 173g-195g per cup (6% band).
Why this happens: fine powders and leaveners settle during storage, changing cup density.
Only with adjustment. Baking powder is weaker, so recipes usually need more of it and may brown less.
It is the better fit when the recipe does not contain enough acid to activate baking soda on its own.
Add a little baking powder to hot water. If it bubbles right away, it is still active.
1 cup of baking powder weighs 184 grams.
