Simple Sourdough recipe for a Pullman Loaf Pan

So I have this big pan that’s 13" x 4" x 4" and makes square slices of bread. It’s nearly twice the size of most bread pans and not a super common size for recipes.

The pan

I spent some time doing some math and test loaves to come up with a good, simple sourdough recipe that would work well with it. This is just the recipe & ingredients. It doesn’t include the method of like how many hours to do each step…. I’ll try to take better notes the next few times I bake this and update this post later.

Recipe

Levain

Mix the levain the night before and let it rise overnight.

Misc Notes

  • Pan Volume:

    • Pullman Loaf pan is 13" x 4" x 4" = 208 in^3
    • Bread I’ve been making lately is in a 8.5 x 4.5 x 2.5 pan = 95.6 in^3
    • Pullman loaf has 2.15x the volume of the regular bread pan.
  • Recipe Scaling:

    • The loaf pan recipe I’ve been using is ~740g of dough.
      • Let’s say 20% of the dough rises above the pan, so only 740g * .80 = 590g of dough fills the volume of the pan
    • Then scaling up, I’d get 590g * 2.15 = 1,270g total of dough?
      • KA says the pullman pan holds 5-6 cups of flour.
      • The recipe would be 700g of flour or 700g / 120g = 5.833 cups ✔️
