Servings and cooking time scaler

Ingredients scale in proportion to servings; cooking time does not. A bigger pot takes longer to boil, and a thicker tray needs roughly a third more oven time.

Factor: ×1,5

Scaled list
  • 1,5 glass red lentils
  • 1,5 onion
  • 1,5 tablespoon butter
  • 0,75 teaspoon cumin
  • 9 glasses water

How to scale a recipe to a different number of servings

  1. Find the factor. Divide the servings you need by the recipe's servings. Going from 4 to 6 is a factor of 1.5.
  2. Multiply the ingredients. Multiply each ingredient. Add salt and spices at three quarters of the factor first, then taste.
  3. Pick the pan. If the pot or tray stays the same, the layer gets thicker; pick a wider base to keep the same depth.
  4. Adjust the time. Stovetop time stays the same but the boil comes later. In the oven, a thicker layer needs about a third more time at the same heat.
