Frequently Asked Questions
How to scale a recipe?
Divide desired servings by original to get scaling factor. Multiply every ingredient by this factor.
Do cooking times change when scaling?
Not linearly. Keep oven temperature same but expect longer baking. Check doneness with visual cues.
How to scale spices?
Scale slightly less than other ingredients. Start with 75% of scaled amount and adjust to taste.
Can I scale baking recipes?
Baking is precise. For large batches, make multiple batches rather than scaling up one recipe.
Handle fractional measurements?
Convert to decimals: 3/4 cup x 3 = 2.25 cups. Weight (grams) offers more precision.
