Ingredients

  • 360g King Arthur bread flour
  • 220g warm water (can use anywhere from 200-240g)
  • 200g liquid perferment
  • 1 egg yolk
  • 13g sugar
  • 15g salt
  • 1 stick frozen butter

Steps

This recipe will follow the same general flow as the Basic Sourdough Bread Recipe, with some modifications

  • Make the Liquid Preferment: this is just 90g flour, 90g water, 20g starter allowed to rise for ~8-12 hours. In my case, this is the same ratio I use for my starter, so I can just use ripe starter
  • Combine all ingredients except the butter in a bowl and mix until fully combined. Transfer to a lightly greased dough bucket and let rise for 20 mins
  • Perform 2-3 sets of bowl folds, separated by 20 mins
  • Spread the dough onto a wet countertop so it forms approx a 5 x 14 rectangle
  • Grate 2/3rds of the butter onto the dough and perform a letter fold
  • Grate the remaining butter onto the dough and roll up into a log
  • Place dough back in bucket and let rest for 30 mins
  • Perform 2 coil folds, separated by 30 mins
  • Allow dough to rise for 2-4 hours (likely will not be doubled in size)
  • Shape the dough into a batard and place into a banneton. We don’t need to preshape.
  • Cover banneton and leave in fridge for 12+ hours
  • Bake in the typical fashion (preheat oven to 450 w/dutch oven, score dough, bake in dutch oven with lid on for 25 mins, remove lid and bake for another 20+ mins)
