this recipe is adapted with the flours from Shipton Mill from the wonderful blog of Dietmar Kappl Austrian super baker par excellence https://www.homebaking.at/

I start the leaven and poolish the evening before. Then make the dough the next day in the evening and finish baking the next morning early before I go to work.

shape into round loaves and leave on bench rest for 15 to 20 minutes . Then reshape or make into a bloomer shape if desired.

Rest in proofing baskets overnight in the fridge between 12 to 16 h .

Baking

if possible bake in a cast iron casserole with the lid on. Heat the casserole and lid to 250 C . In my oven this will take 25 to 30 minutes

Put the bread from the fridge onto a bread paddle or directly into the casserole .Cut the top as desired and bake with the lid on for 25 minutes.

Drop the temperature to 220C

Now remove the lid to get a nice crust and continue baking the loaf for a further 15 to 25 minutes until crusty and golden brown.

Enjoy
