Frequently asked

How do I double or halve a recipe?
Multiply every ingredient quantity by your serving ratio — 2 to double, 0.5 to halve. This tool applies the ratio to every line at once, including decimals and simple fractions like 1/2 and ½.
Does scaling a recipe change the cooking time?
No. Ingredient quantities scale linearly, but cooking time, pan size and oven temperature do not. Scale the quantities here, then use judgment on time and equipment.
The scaler multiplies the leading number on each line by your serving ratio (handles decimals and simple fractions like 1/2 and ½). It doesn't change cooking times or pan sizes — use judgment for those.
