The arithmetic
no recipe
ever shows you.
Doubling a family recipe, halving a sheet of cookies, or turning a European bake into something your imperial measuring cups can handle. The math is fiddly. We do it so you don't have to.
Up, down, sideways
Parses fractions, decimals, and unicode glyphs. Returns readable fractions back.
Cups ⇄ grams ⇄ °C
Volume, weight, and temperature — with a quick-reference for the things you forget at 7 am.
For when you're out
17 staple ingredients, several swaps each, with ratios and editor notes on which is which.
Quick macro math
USDA per-100g averages for 25+ ingredients. A sanity-check, not a meal plan.
A cup is
