Most ingredients scale cleanly: double the recipe, double the flour. A few don't. Flavor perception is logarithmic — "twice as much" doesn't taste twice as strong. Here's the short list of ingredients that need a softer multiplier.
The usual suspects
- Salt — scale at 80–90% of factor. Human salt perception saturates; more salt tastes increasingly salty by smaller margins.
- Garlic, black pepper, cayenne — scale at 75–85%. Doubling produces a notably hotter / sharper result than expected.
- Vanilla extract, almond extract, mint — scale at 70–85%. Strong aromatics scale hard.
- Leaveners (yeast, baking soda, baking powder) — scale at 80–90%. More leavener means faster rise, not bigger. Yeast excess produces off-flavors.
- Thickeners (cornstarch, flour in sauces) — scale at 75–90%. A doubled sauce thickens more than proportionally due to heat transfer and evaporation changes.
What still scales 1:1
Most of the recipe:
- Flour, sugar, butter, oil — multiply straight.
- Liquids (water, milk, stock, juice) — straight.
- Meat, vegetables, fruit — straight.
- Eggs — straight (with rounding for halves).
- Cheese, chocolate, nuts — straight.
The practical approach
Scale bulk ingredients by the exact factor. Scale strong-flavor ingredients by 80–85% of the factor. Cook. Taste before serving and adjust up or down. The fastest path to a balanced doubled recipe is to start slightly conservative and add, not to overshoot and fight it back.
