Using weight measurements (grams, ounces) provides a consistent and accurate way to measure ingredients, eliminating discrepancies caused by volume-based measurements that vary between metric and US customary systems, leading to more reliable recipe results.
When sharing recipes internationally, the biggest hurdle is often the difference between metric (grams, milliliters) and US customary (cups, ounces, tablespoons) measurement systems. Volume measurements, like cups, can be particularly problematic because they are not standardized. A 'cup' of flour can vary significantly depending on how tightly the flour is packed, the size of the measuring cup, and even the humidity. This variation can lead to inconsistent results when someone tries to recreate a recipe using a different measuring system or technique.
Weight measurements, on the other hand, are much more precise. A gram is a gram, regardless of where you are in the world or how tightly packed the ingredient is. By providing ingredient amounts in weight (e.g., grams for dry ingredients, grams or milliliters for liquids), you eliminate the ambiguity associated with volume measurements. This ensures that anyone, regardless of their preferred measuring system, can accurately measure the ingredients and achieve the intended result. To convert, one can easily use online converters or a kitchen scale that displays both metric and US customary units. This level of precision is especially crucial in baking, where even small variations in ingredient ratios can significantly impact the final product.
Always include both weight and volume measurements in your recipes, if possible. This caters to a wider audience and provides a backup for those who may not have a kitchen scale. However, prioritize the weight measurements for accuracy and consistency, and clearly indicate that weight is the preferred method.
