Food and cooking

Servings, portions, baking quantities and what a recipe really needs.

Cooking by the numbers

The recipe scaling calculator changes an ingredient amount for more or fewer servings, and can switch it to a handier unit. Seasoning and leavening such as salt and baking powder do not always scale evenly, so taste as you go when making a much larger batch.

The rice to water and coffee to water calculators use the ratios cooks rely on, and let you change the ratio if you like your rice softer or your coffee stronger. The pizza size calculator compares pizzas by area, which is how you find out which deal gives the most pizza for the money.

The turkey cooking time calculator gives roasting time by weight. Always check the thickest part of the thigh with a thermometer: it should read 165°F (74°C) before serving.
