Why Cup Weights Vary in Leavening
Micro-ingredients like chemical leaveners and bio-yeasts require rigorous weight control. Pure sodium bicarbonate (baking soda) is a dense crystalline powder weighing 220 grams per cup (4.6g per tsp). Commercial baking powder combines baking soda with monocalcium phosphate, sodium aluminum sulfate, and cornstarch buffer; this blend reduces bulk density to 192 grams per cup (4.0g per tsp). Granular active dry yeast and instant yeast consist of dehydrated yeast spheres weighing 150 grams per cup (3.1g per tsp). Over-measuring leaveners by even 2 grams causes bitter chemical flavors and collapsed cake structures.
