Quick recipe scaler

Halve, double or resize a recipe

Quick:
Recipe rescue

Tell FOOGG what changed. Get the right calculator.

Recipe math gets confusing when the real problem is not “scale this recipe” but “I only have one ingredient,” “my package is a different size,” or “my pan changed.” Pick the constraint and FOOGG will send you to the most useful workflow.

Scale from what you have

Only have 327 g of the 500 g flour the recipe needs?

Scale the entire ingredient list from the amount of one ingredient you actually have.

More than a ratio

See what the change does to the whole batch

FOOGG shows the whole-batch impact of a recipe change: maximum servings from several pantry limits, leftovers after scaling, alternative whole-package batch sizes, pan-capacity differences, and ingredient/instruction mismatches.

Pantry impact

Track several ingredients at once and see the bottleneck, maximum yield and leftovers.

Find the limiting ingredient

Package options

Compare one, two and three package batch sizes before scaling the ingredient list.

Compare packages

Pan fit

Use your actual pan dimensions to estimate capacity and when to start checking the bake.

FAQ

Common questions

Can I plan pizza dough by total weight?

Yes. The dough hydration calculator converts baker’s percentages into flour, water, salt and yeast grams and shows grams per dough ball.

Does recipe cost equal my shopping bill?

No. The recipe cost calculator separates consumed ingredient cost from full-package shopping, using the local prices you enter.

Does FOOGG upload my recipe?

No. The current tools process pasted recipe text in your browser. There is no account system or recipe database.

Can FOOGG scale every ingredient line?

It scales lines that begin with a recognizable number, decimal, fraction, or common Unicode fraction. Lines such as “salt to taste” stay unchanged so you can review them manually.

Is the baking-time estimate exact?

No. Pan geometry can suggest when to start checking, but oven calibration, batter composition, material and fill depth all matter. FOOGG deliberately presents a range and tells you to verify doneness.
