Baker's percentages are the secret language of professional bakers: flour is always 100%, and every other ingredient is a percentage of the flour's weight. This method allows you to easily scale any recipe up or down, understand ingredient ratios at a glance, and even develop your own recipes with precision. It removes the guesswork and makes consistent results achievable every time.
Unlike standard percentages where all ingredients add up to 100%, in baker's percentages, the total weight of flour in the recipe is always 100%. All other ingredients (water, salt, yeast, sugar, fat, etc.) are expressed as a percentage of that flour weight. This means the total percentage will often exceed 100%.
Convert Your Existing Recipe to Weights: If your recipe uses volume measurements (cups, spoons), convert them to grams or ounces using a digital kitchen scale. This is crucial for accuracy. For example, 1 cup of all-purpose flour is typically 120-125g.
Calculate Baker's Percentages for Each Ingredient:
(Ingredient Weight / Total Flour Weight) x 100 = Baker's PercentageDetermine Your Target Flour Weight: Decide how much flour you want to use for your new batch. This is the only number you need to change. For instance, if you want a smaller loaf, you might aim for 300g of flour. If you want two large loaves, maybe 1000g of flour.
Calculate New Ingredient Weights: Now, use your target flour weight and the calculated baker's percentages to find the new weight for each ingredient:
(Target Flour Weight x Ingredient Baker's Percentage) / 100 = New Ingredient WeightWeigh and Mix: Accurately weigh out all your ingredients using your digital scale and proceed with your recipe as usual.
Pro tip: Always use a digital kitchen scale for weighing ingredients. Volume measurements (cups, spoons) are notoriously inaccurate for baking, especially with flour, which can vary wildly in density depending on how it's packed. Precision is key to consistent bread.
1 cup of all-purpose flour — recipe ingredient.
300g x 70 — recipe ingredient.
Dry and liquid measuring set. Baking requires precision — guessing ruins results.
Heavy-duty aluminum sheet pan. The workhorse of any oven — cookies, roasting, pastry.
For sifting flour, straining sauces, removing lumps. Used in most baking recipes.
Balloon whisk for eggs, cream, sauces. Essential for any recipe that says 'whisk until smooth'.
Large wood or plastic board. Get one big enough that food doesn't fall off while chopping.
Non-stick baking liner. Prevents sticking, easy cleanup. Buy a roll, not pre-cut sheets.
Nesting bowls for prep, mixing, whisking. Stainless steel won't stain or absorb odors.
Heat-resistant spatulas for scraping bowls, stirring sauces, folding batters.
One good knife replaces a drawer of mediocre ones. Victorinox Fibrox is the pro budget pick.
For spreading frosting, glazes, and cream layers evenly. The tool pastry chefs actually use.
Wire rack for cooling baked goods evenly. Prevents soggy bottoms from steam trapped underneath.
For pastry, cookies, pie dough. French style (no handles) gives better control.
KitchenAid or equivalent. Hands-free mixing, kneading, whipping. A lifetime investment for serious baking.
Tri-ply stainless steel. For sauces, custards, reductions. The pan you'll use most.
Essential for accurate weighing of ingredients, which is the foundation of baker's percentages. Look for one that measures in grams and ounces with at least 1g precision.
A good resource for understanding fundamental bread techniques and often includes recipes already in baker's percentages, or teaches you how to apply them.
Useful for accommodating scaled-up recipes and for bulk fermentation. A set with various sizes offers versatility.
The primary ingredient in any bread recipe. Having a larger bag on hand is economical if you plan to bake frequently.
Invaluable for handling sticky dough, dividing portions, and cleaning your work surface. A metal one is more durable and effective than plastic.
