Resize a recipe from its original servings to the number of servings you want to make.
Enter the original and required serving counts, add each ingredient amount, then calculate the scaled quantities before adjusting seasoning and cooking time by judgement.
Spices, raising agents and cooking times do not always scale perfectly in very large or very small batches.
Most ingredient quantities can be multiplied by the ratio between the original serving count and the new serving count. That is the arithmetic this tool performs. A recipe for four scaled to six, for example, uses a factor of 1.5 for each entered ingredient.
Seasoning, chilli, raising agents and thickeners may need judgement rather than a perfectly proportional increase. Doubling ingredients also does not automatically mean doubling baking or simmering time. Pan size, food depth and appliance capacity can alter cooking performance. Use the calculated quantities as the ingredient plan, then check texture, seasoning and doneness during cooking. For very large batches, splitting the mixture between suitable pans can give a result closer to the original recipe.
