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.
