1 · Double it, halve it, or one-and-a-half it
Most recipes want to be multiplied — not feared. Pick an amount, choose what to do with it, and watch each step.
2 · Unit conversions, worked out
Cups to tablespoons, quarts to liters — with every step written out so the math stops being magic.
3 · Pan-size swaps
Swapping an 8×8 for a 9×13? Compare the areas, get the multiplier, and your bake time gets a gentle warning.
4 · What does one serving cost?
List what you spent on each ingredient, say how many servings it makes, and this does the division politely.
| Ingredient | Cost you paid ($) | |
|---|---|---|
| Batch total | — |
Enter what the ingredient actually cost you at the store (the whole bag, if you bought a whole bag). Good enough beats exact.
