FAQ
Guide to calculating recipe portions
How does the portion calculation work?
The formula is simple: scaled quantity = (original quantity / original servings) × desired servings. For example, if a recipe for 4 serves requires 400g of flour, for 10 serves you need (400/4) × 10 = 1000g.
Do all ingredients scale linearly?
For most ingredients, linear scaling works well. However, for salt, spices, yeast and leavening agents it is advisable to scale more cautiously.
How do I manage cooking times when scaling a recipe?
Cooking times do not scale linearly like ingredients. Temperature generally remains unchanged; monitoring the cooking is the most reliable method.
Can I use fractions in quantities?
Yes, the calculator supports decimal values. For example, you can enter 0.5 for half a cup or 1.5 for a cup and a half. The result is rounded to two decimal places for convenience.
How are the quantities worked out again?
Each quantity is divided by the original servings and multiplied by the ones you want. Four hundred grams of flour for four people therefore become a thousand grams for ten.
Do all ingredients scale the same way?
No. Flours, liquids and fats follow the proportion, while salt, spices and raising agents are better raised cautiously and tasted, because their effect does not grow in a straight line.
What about the cooking times?
Times do not follow the proportion of the quantities. The temperature usually stays the same, while the duration has to be watched, because it depends on thickness and tin more than on amount.
