    How it works

    The scaler reads the amount at the start of each line: whole numbers, decimals, fractions like 1 1/2 or ¾, and ranges like 2–3. It multiplies it by the new servings divided by the old, and writes it back as a kitchen fraction. Grams and milliliters stay as decimals.

    Lines without an amount, like "salt to taste", are left alone. Can sizes in brackets, like "1 (400 g) can tomatoes", keep their size; only the number of cans changes.

    What doesn't scale

    • Pan size. Double the batter, double the pan area: one 9-inch round becomes two, or a 9×13 instead of an 8×8.
    • Cooking time. More food in the same pan takes longer. More pans in the oven can need a few extra minutes. Check early.
    • Salt, spice and leavening. Go a little under when you scale up a lot, then taste.

    Questions

    How do I double a recipe?

    Set the servings to twice the original, or tap 2×. Every amount doubles. Cooking times usually stay close to the original, but a bigger pot or pan can take longer to heat.

    Can I scale baking recipes?

    Yes, but weigh the flour and sugar if you can, and change the pan size to match. Doubling a cake batter into the same pan will not bake through.

    What about eggs?

    If an amount comes out as half an egg, beat one egg and use half of it, about 25 grams.

    Does it change salt and spices?

    It scales them like everything else. When you double or triple a recipe, start with a little less salt and spice and taste before adding the rest.
