things people ask

• How much baking soda is in a typical cookie or quick-bread recipe?
  A standard chocolate chip cookie recipe uses 1 teaspoon (6 g) of baking soda for around 2 dozen cookies. Pancakes and muffins usually call for 1/2 teaspoon (3 g) per batch. Irish soda bread is the outlier on the high end at about 1.5 teaspoons (9 g) per loaf, since it relies on baking soda alone — no yeast — for the entire rise.
• What does 1/4 teaspoon weigh, and does it really matter at that scale?
  1/4 teaspoon of baking soda is 1.5 g and 1/2 teaspoon is 3 g. At this scale precision genuinely matters — baking soda is roughly four times stronger than baking powder, so doubling a 1/2 teaspoon by mistake leaves a soapy, metallic aftertaste and produces over-browned, cracked tops. Weigh on a 0.1 g scale if your recipe runs below 1/2 teaspoon.
• Why does my recipe use both baking soda and baking powder by the teaspoon?
  Recipes pair them when there is some acid in the batter — buttermilk, brown sugar, cocoa, yogurt — but not enough to neutralize the leavening on its own. The teaspoon of baking soda reacts with the acid for flavor balance and browning, while the baking powder supplies the rest of the lift independent of acidity. The two work on different timelines, which gives a more even rise.
