Steps

30 minutes

1

Prepare the sourdough starter the night before by mixing all the starter ingredients. Adjust the water as needed to achieve a dough that is not too wet or too dry.
2

Mix all the dry ingredients together. Add the sourdough starter. Mix in the fats (butter and egg yolks).
3

Gradually add the egg whites, checking the consistency as you go. Let the dough rest. Punch down the dough and divide into 80-gram (about 2.8-ounce) balls. Cover with a clean kitchen towel.
4

Brush with oil and add the topping (for the topping, simply mix all the topping ingredients together). Bake at 375°F (190°C) for 15 minutes.
