RecipeScaler

Scale any recipe to a new serving size, convert cooking units, and run kitchen timers. On-device.

Scaling a recipe is not uniform multiplication, and the exceptions are what ruin dishes. Cooking times do not scale — a double batch in one pan takes longer than double the time or none at all, depending on depth. Salt and strong spices generally scale sub-linearly. Leavening and pan size interact in ways that make baking the least forgiving case.

Unit conversion adds its own hazard, since cups measure volume and flour packs differently depending on how it was scooped. Weight is reproducible in a way volume is not, which is why every serious baking source has moved to grams.
