Total Time 2 hours 35 minutes
Serving Size 8 large buns

Equipment

  • Kitchen scale
  • mixing bowl
  • spoon
  • baking tray
  • Parchment paper

Ingredients

For the dough

  • 120 g sourdough discard (unfed, room temp)
  • 240 g warm milk
  • 40 g honey or sugar
  • 1 large egg
  • 300 g bread flour
  • 200 g whole wheat flour
  • 5 g instant yeast
  • 8 g salt (1½ tsp)
  • 60 g tallow or butter (softened)

For the topping

  • 1 egg
  • 1 Tbsp milk
  • ¼ cup sesame seeds

Instructions

  • Combine wet ingredients: In a large bowl, whisk together sourdough discard, warm milk, one egg, and sugar until smooth.
  • Add dry ingredients: Stir in bread flour, whole wheat flour, instant yeast, and salt until a shaggy dough forms. Let rest 10 minutes to hydrate the whole wheat flour.
  • Incorporate fat: Mix softened tallow (or butter) into the dough until fully incorporated.
  • Knead the dough: Knead by hand for 8–10 minutes or in a stand mixer for 5–6 minutes, until the dough is soft, slightly tacky, and stretchy.
  • Bulk ferment: Place dough in a greased bowl, cover, and let rise until doubled in size (about 60–90 minutes).
  • Divide and shape: Turn dough onto a lightly floured surface. Divide into 8–10 pieces (depending on desired bun size). Shape each portion into a tight ball by tucking the edges underneath.
  • Final proof: Place buns on a parchment-lined baking sheet, flatten slightly, cover, and let rise until puffy and about 1½ times their original size.
  • Bake: Preheat oven to 190°C / 375°F. Brush buns with egg wash and sprinkle with sesame seeds. Bake 15–18 minutes until golden brown.
  • Cool: Let buns cool at least 30 minutes before slicing to set the crumb.

Notes

Storage Tips:
  • Room temp: Store cooled buns in a linen bread bag up to 2 days.
  • Freezer: Slice, flash freeze, then keep in an airtight bag up to 3 months.
  • Reheat: Toast or warm in oven straight from frozen for best texture.
