How to Use the Recipe Scaler
Enter the recipe's original ingredient list and serving size, then enter the target serving size — the scaler calculates the correctly proportioned amount for every ingredient, applying the exact scaling factor consistently, including for an arbitrary target that doesn't divide evenly into the original.
The Recipe Scaler handles the multiplication across a full ingredient list precisely — here's how to use it and what to double-check afterward.
Entering the original recipe and target serving size
Enter each ingredient with its original quantity, along with the recipe's original serving count and the desired new serving count — the tool applies the correct scaling factor across every ingredient automatically.
Adjusting seasoning and leavening after scaling
As covered in the scaling guides, treating the scaled amounts for salt, strong spices, and leavening as a starting point to taste and adjust — rather than the final, fixed amount — generally produces a more reliably balanced result than a strict, uniform multiplication.
