Ratio baking
Ratio baking is working from simple weight proportions of ingredients, such as 3 parts flour to 2 parts fat to 1 part water, instead of fixed measured amounts.

Professional bakers often think in ratios by weight. Wayne Gisslen's Professional Baking gives the classic example of 3-2-1 pie dough: the numbers refer to the ratio of ingredients by weight, 3 parts flour, 2 parts shortening and 1 part ice water. Because the parts are weights, the same ratio works for a small batch or a large one.
Bread makers use a related idea called baker's percentage. Jeffrey Hamelman's Bread explains that flour is set at 100 percent and each of the other ingredients is expressed as a percentage of the flour's weight, found by dividing the ingredient's weight by the flour's weight and multiplying by 100.
Working by ratio makes it easy to scale a recipe, compare formulas, or adjust one ingredient, such as the water in a dough, without rewriting everything. It depends on weighing ingredients on a scale rather than using cups.
