Adjust ingredient amounts for a different yield
Enter the recipe’s original servings and your desired servings, then edit the ingredient table. Each numeric quantity is multiplied by the ratio between those two yields. Amounts can be decimals, simple fractions or mixed numbers such as one and one half. Units and ingredient names stay unchanged, so the tool does not invent a conversion between cups, grams or different ingredient densities.
Use practical judgment beyond the arithmetic
A blank amount or the phrase to taste is retained without numeric scaling. Other quantities are rounded to four decimal places for a readable result. Cooking duration, pan geometry, oven temperature and food-safety requirements do not scale by the serving ratio, and seasonings or leavening can need separate adjustment in a large batch. The tool handles ingredient arithmetic only. Review indivisible items such as eggs and choose an appropriate preparation method for the new yield.
