When scaling doesn’t work linearly
Baking is more sensitive — yeast amounts, leavening, and surface-to-volume ratios don’t scale 1:1. For very large or small adjustments, baking benefits from rounding to the next sensible measure rather than exact math.
Cooking times
Cooking time doesn’t scale with quantity for most things. A doubled stew takes only slightly longer to come to a boil but the same simmer time. Roasts: per-pound time roughly applies, but check internal temperature.
Salt and seasoning
Salt scales linearly but taste threshold doesn’t. When doubling spices and aromatics, start with 1.5× and adjust to taste. Better to under-season then add more than over-season permanently.
