Step 1

Mix all the sponge ingredients to a sticky dough in a large bowl, cover with cling film and leave in a warm place for an hour.

Step 2

Heat up the milk and water to the boiling point, mix in the butter and leave to cool down a bit. Mix the flours with the salt and sugar, add the sponge and the butter/milk mixture and stir to a dough, if possible in a standing mixer with the dough hook attachment. Knead for quite a long time until it comes away from the side of the bowl.

Step 3

Leave to prove in the bowl for 15 mins, then turn out and divide into 9 pieces, about 160g each. Shape each piece into a ball, dip or roll in flour, place on a baking sheet lined with parchment (you’ll need at least two sheets), cover with a tea towel and leave to rise for about 40 – 60 minutes.

Step 4

Preheat the oven to 200C/400F/gas

Step 5

Bake the baps for 20 minutes, until lightly browned.
