Kitchen Scaler
Reckonersweight 1reckoner · computes, doesn't store
The recipe serves four; you are feeding eleven, one of whom eats like three. The Kitchen Scaler multiplies a recipe up or down and gives you the adjusted quantities, so every ingredient scales together and nothing is left at the original amount out of spite. It computes and forgets — your grandmother's recipe stays exactly where it belongs.
This is not a screenshot. It's the real tool, running right here — go on, put something in it.

Questions people ask
How do I scale a recipe from 4 servings to a different number?
Tell it the original servings and the servings you need, and it works out each ingredient's new quantity. The whole recipe moves together, which is where hand-scaling usually goes wrong.
Do I have to upload my recipes to use it?
No, and you cannot — it stores nothing at all. It is one HTML file running offline in your browser; you type quantities, it computes, and everything vanishes when you are done. The family recipes remain a family matter.
Can it scale a recipe down as well as up?
Yes — halving for two is the same arithmetic as tripling for a party, and it does both without complaint. Whether a quarter of an egg is achievable remains between you and the egg.
