Do cooking times scale proportionally?

No. Cooking time does NOT scale linearly with quantity. Volume and pan size change, affecting heat transfer. Always use a thermometer or check doneness manually when scaling.

Does baking scale well?

Baking is less forgiving than cooking. Leavening agents (baking soda, baking powder, yeast) should not be scaled fully — use 75% of the scaled amount when more than doubling.

How do I scale seasoning?

Scale salt and spices conservatively — start with 75% of the calculated amount and adjust to taste. Strong flavours intensify less predictably than neutral ingredients.

Recipe Scaling Calculator

The Recipe Scaling Calculator works out the scaling factor needed to adjust a recipe from its original serving size to your desired number of servings. Simply multiply each ingredient quantity by the scaling factor to get the right amount. Perfect for cooking for large groups or scaling down for a smaller meal.

Frequently Asked Questions

Scaling factor = Desired Servings ÷ Original Servings. If a recipe serves 4 and you want 10: factor = 2.5. Multiply every ingredient by 2.5. For example, 200g flour becomes 500g.
