Scale a Recipe Up or Down

Use this when a recipe serves the wrong number of people. It rewrites the amounts and flags what does not scale in a straight line, such as spices, baking powder and cooking time.

Works inChatGPTClaudeGemini

Rewrite the recipe below to serve [NEW NUMBER] people instead of [ORIGINAL NUMBER]. Give me the new ingredient list with exact amounts in [CUPS AND TABLESPOONS / GRAMS], any change to pan size, cooking time or temperature, and anything that does not scale well, such as spices, baking powder or salt. If a number is awkward, such as a third of an egg, suggest the easiest practical fix. Recipe: [PASTE THE RECIPE HERE]

Tip: Season in steps and taste as you go when you scale up, because spices and salt do not always scale in a straight line.

What to fill in
