Scaling is not always linear
Most ingredients scale linearly, but salt, leavening, spice heat, pan size and cooking time may need judgment. Use the result as a starting point, then adjust for taste and method.
Example
If a recipe uses 2 cups for 4 servings and you want 10 servings, the scale factor is 10 / 4 = 2.5. The scaled amount is 2 x 2.5 = 5 cups.
Common mistakes
Keep the unit consistent: cups stay cups, grams stay grams and tablespoons stay tablespoons. Do not mix volume and weight without a density conversion.
Limitations
Very large or small batches may need different pan sizes, mixing times, cooking times and seasoning adjustments.
