In your bread machine basket, pour in your sourdough starter then the flour

Add in the sugar/honey, salt and the butter

Pour in your water around the edges of the baking basket

Set your bread machine to the kneading cycle for 30 minutes or if it has a sourdough dough cycle use that. For the Panasonic SD-ZX2522 use menu 29. For the Panasonic SD-ZB2512 use menu 26.

Once your sourdough bread has finished kneading, let your dough rest and proof for 3-4 hours or until it has risen by about 50% of its original size.

Once proofed, sprinkle some flour on top and score lengthwise with a sharp knife or a blade. Pop any large bubbles that may have appeared on the surface.

Set your bread machine to the bake programme and set its timer for 1 hour and 15 minutes.

Once done, remove the basket and tip the bread over to an airing rack. Let it cool down for about an hour before cutting it.
