Thank you for that! And now that you know what baker’s percentage (BP) is, you might be wondering what you’re supposed to do with it. So, again based on the simple sourdough formulation above, but with the addition of walnuts.A number of people left comments or sent email saying that they found Part 1 of my Baker’s Percentage Tutorial helpful. The addition of walnuts means the weights of all the other ingredients will decrease proportionally to give ‘room’ to the nuts – and still maintain a yield of 1.800g – but their percentages will remain the same.
The beautiful thing about the baker’s percentage method is that a baker can work out the weight of these inclusions, while maintaining the total percentages of all the ingredients to create a consistent end result. Now, let’s really mix it up and add raisins or nuts, which, won’t impact a recipe for a single loaf, but can drastically change the yield when working on a bigger scale. To double a recipe, the weight of each ingredients will be multiplied by two, but the percentages will stay the same – a similar concept when halving a recipe. To figure out the conversion factor, divide the new desired total yield by the sum of the percentages:įormula conversion factor = - Now you want to make three loaves with a total yield of 2.700g.įirst, add the percentages: 80% + 20% + 76% + 1.9% + 0.8% = 178.7% Let’s work on the sourdough formula above, which makes two 900g loaves, a total yield of 1.800g. Steps to mix it upĪnother reason to get comfortable with baker's percentages is to easily scale a recipe up or down or to add, remove or change up ingredients. The total percentage will be more than 100%, because all the other ingredients are with respect to the flour weight – a single ingredient – rather than with respect to the weight of all the ingredients. Note: The flour percentages must always add up to 100%. Take a simple sourdough bread formula, which typically has 100% flour, 60%-100% water, around 1.8%-2.3% salt and some preferment percentage. The total weight of the dough is thus 100g wheat flour + 20g rye flour + 96g water + 2.4g salt = 218.4g of dough, while the total percentage of the dough has increased to 182% (100% flour + 80% water + 2% salt).Ī baker must follow this method for any and all additional ingredients – butter, sugar, oil, preferment, inclusions. The method is the same to add 2% salt: 0.02 x 120g (of the base flours) = 2.4g So, to make a wheat/rye 80% hydration loaf: 0.8 (80% water converted to a decimal) x 120 (total weight of combined flours in grams) = 96g of water is required.
To calculate the hydration percentage of a recipe, which results in a more open crumb, divide the total weight of the water by the total weight of the flour and multiply it by 100.įor example, a high hydration (80%) loaf comprises 100g of flour and 80ml of water = total percentage is 180%. The addition of other flour varieties – say 20g rye flour to 100g wheat flour, which makes a total flour weight of 120g – is still represented as 100%. Secondly, the weight of every other ingredient is a percentage of that flour weight, and thirdly, the two combined calculate the total percentage of the dough. There are three rules:įirstly, the total weight of the flour – be it 100g or 250g – always equals 100%. The cornerstone is based on the total weight of flour a formula contains, while the individual weight of each ingredient – water, salt, preferment or mother dough, inclusions – is a percentage of that total flour weight. It’s also the way bakers communicate with one another when sharing formulas.īaker’s math is essentially easy to understand, as long as weights and percentages are kept in mind. It’s particularly helpful for a craft baker wanting to adapt and scale up that recipe handed down the generations, to assess a formulation and spot any gross errors, and to determine what the baked result might be like.
