Most recipes scale cleanly — but some ingredients and cooking times don't. This tool gives you the multiplier and flags what to watch for.
What doesn't scale linearly
- Salt and spices: especially when scaling down.
- Baking recipes: ratios are sensitive. Don't scale baked goods casually.
- Cooking time: a pot of soup doesn't cook twice as long to feed twice as many.
- Pan size: doubling usually needs a wider pan, not deeper.
