A recipe scaler multiplies or divides ingredient quantities when changing the number of servings. It adjusts every ingredient by the same scaling factor, though baking requires extra care as leavening and seasoning may not scale perfectly linearly.

Guide étape par étape

1. 1Scaling factor = Desired servings / Original servings
2. 2New quantity = Original quantity × Scaling factor
3. 3Baking note: leavening (yeast, baking powder) should scale at 75% of the calculated factor for large increases
