Place the starter into the bowl of a mixer. Add flour, yeast and salt.
Using the hook attachment, mix ingredients together and slowly add the water while the mixer is mixing.
Ingredients will develop into a dough. Knead for several minutes.
Remove bowl from mixer and cover. Set aside and allow the dough to rise to twice its original size.
Punch down and allow to rise again.
Form dough into a loaf and place in a sandwich pan. Cover and allow to rise until the top of the dough comes up to the pan edge.
Bake at 425ºF (218ºC) for about 25 to 30 minutes.
Once done, remove from the pan and allow to cool. Slice once the bread has reached room temperature.
