It doesn’t matter whether you’re increasing a recipe or decreasing it — the procedure for adjusting the ingredient quantities for a different number of portions is the same. We call this scaling a recipe. When scaling a recipe it’s important to know how to convert back and forth between different measurements. The first thing you need to do is calculate your conversion factor, which is a number you’re going to use to convert all the quantities. There’s a tiny bit of math involved, but it’s OK to use a calculator — that’s what they’re there for! To find your conversion factor, simply divide the desired number of servings by the original number of servings. The resulting number is your conversion factor. Keep in mind; some ingredients will have a ‘weight’ or percentage of importance in scaling, and so will need to be adjusted differently.
Deciphering between the different cooking abbreviations and their proper unit of measurement can help make sure your dish comes out exactly as imagined. Often times, different books will use different abbreviations, which can cause confusion when putting together a dish.
