How it works

Updated September 2026

Scale your pastry cream recipe

Use your recipe’s finished yield and original ingredient weights. The calculator preserves those proportions when planning a larger or smaller batch.

Factor = target finished yield ÷ original finished yield; new ingredient mass = original mass × factor

Read the result with its conditions

All displayed weights come from your inputs; no fixed recipe is substituted. Use the factor for any additional recipe ingredients. Weigh fractional eggs after mixing them as the recipe allows. Follow the recipe’s cooking and refrigeration steps. This calculation does not predict evaporation, cooling time or storage life.

Example Scenarios

Enter 1,000 g original yield, 1,500 g target and original ingredient weights.

→ The example’s 800 g milk becomes 1,200 g; 120 g eggs or yolks becomes 180 g.

Common Mistakes to Avoid

Entering an egg count in a weight field

Weigh the eggs or yolks required by the actual recipe and enter grams. Keep its preparation and cooking instructions.

FAQ

Two recipes can produce the same finished yield from different ingredient weights. Yield alone cannot identify your recipe.

Use the one-ingredient recipe scaler for chocolate and cream. Pastry cream has its own ingredients and cooked-yield basis.
