The dough will be fermented and smell a bit like beer. It will look like a thick gluey mixture.
Add the remaining flour, water, and salt. Mix until you have a nice, cohesive dough. Knead for five minutes.
Let rest for 30 minutes.
Divide the dough in two. Split the bacon and stilton and add to each of the pieces of dough, then shape into circles and place place on a lined baking sheet.
Let dough prove for 1 hour.
Preheat oven to 400°F. Dust loaves with flour and bake 30 minutes.
Let cool on a wire rack.
