FAQ
Does the tool change cooking time automatically?
No. It scales ingredient amounts and shows review notes, but pan size, oven behavior, simmer depth, browning, storage, and cooking time still need recipe judgment.
What ingredient format works best?
Start each line with a number, decimal, simple fraction, or mixed fraction, such as 2 cups flour, 1.5 cups milk, 1/2 tsp salt, or 1 1/2 cups broth.
When should I use quarter rounding?
Use quarter rounding for everyday cooking when 2 1/4 cups is easier to measure than 2.25 cups. Use decimal output when you want exact math for a careful baking note.
Why do some ingredients get review warnings?
Salt, pepper, hot spices, eggs, yeast, and leavening can change texture or taste when multiplied. The tool keeps them visible so you can adjust after mixing, tasting, or checking the recipe method.
What does max comfortable servings per batch mean?
It is the largest batch your pot, pan, tray, or mixing bowl can handle before crowding changes texture, browning, mixing, or handling. The tool uses it to suggest smaller batches.
What does seasoning start percent do?
It gives cautious starting amounts for salt, pepper, chili, and strong seasonings so you can add part of the scaled amount first, taste or check texture, and adjust before the full batch is committed.
Why include a storage or service note?
Large scaled recipes often fail after cooking because extra portions have nowhere to cool, chill, freeze, or serve. The note keeps that practical decision in the copied plan.
