Baker's percentage

As long as you're making the same bread, no matter how much you want to bake, you may easily calculate the amount of each ingredient with baker's percentage method. To determine the baker's percentage, the weight of flour is always set at 100%. All ingredients are measured by their weight in relation to that of flour. The total must add up to over 100%.

Example :

Calculate the baker's percentage according to the amount listed in a recipe.
Baker's percentage = (weight of a certain ingredient / weight of flour) x 100

Flour - 1000 g (100%)
Sugar - 30 g (30/1000 x 100) = 3%
Egg - 200 g ( 200 / 1000 x 100) = 20%
Sea Salt - 10 g (10/1000 x 100) = 1%
Yeast - 30 g (30/1000 x 100) = 3%

Based on the above percentage and re-compute the weight of each ingredients.
