Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.

Frequently Asked Questions

About 2,268.00 g, based on walnuts having a density of 120g per cup. The exact amount depends on how the ingredient is measured and the specific product.
