How to use this ingredient list

Every ingredient is compared with the total flour. All flour together is always 100%.

What happens next?

  1. Weigh the ingredients in the recipe list.
  2. Mix and knead using the method in your recipe.
  3. Watch the dough: proofing time changes with temperature, flour, and the amount of yeast or starter.

Keep it useful

Not a bare calculator. Not a baking laboratory either.

Exact where possible

Weights, hydration and scaling factors are deterministic and verifiable.

Honest where it varies

Rising times are estimates. Use the baking planner as a guide and check the dough before moving on.

Made to be used

Clear for beginners and quick enough for experienced home bakers.
