I just made a very simple artisan bread. You combine flour, yeast, salt, and warm water in a bowl and let it set for about 24 hours. After that you form it into a ball, let it rest for 30 minutes and then bake it at 450 degrees covered for 30 minutes and uncovered for 15. Anyway, it turned out a little doughy. Could it be underdone? Also, it has a very slightly bitter taste. Any ideas or suggestions?
Your recipe sounds very similar to one I make frequently (it's DH's favorite).
Just a few differences in how I do it:
Combine the warm water, yeast and salt. Add the flour and stir until no dry patches are left.
Let it sit on the counter about 2 hours in a large container that does
not have a tight fitting lid.
Put it in the fridge overnight (or up to 1 week).
When ready to make a loaf, sprinkle the top of the dough in the container with a bit of flour to make handling easier, then grab out a big handful. Quickly form into a ball, tucking edges underneath and making a taut surface.
Put on a parchment covered baking sheet (sprinkle corn meal on the parchment first).
Let rise, uncovered, for 20 minutes.
Then turn the oven on to pre-heat to 450* for 20 minutes (this gives the bread a total of 40 minutes of rising time).
Lightly flour the top of the loaf, make a slash or X on top.
Put a baking dish in the bottom rack of the oven, fill it with boiling water to create steam, and pop the bread into the hot oven.
Bake about 25-30 minutes (till reaches 190* or sounds hollow when you knock it).
Cool completely before slicing.
I usually make up a big container of this dough using 1.5 Tablespoons of yeast, 1.5 Tablespoons of kosher salt, 3 Cups of water and 5.5-6.5 Cups of AP flour. With that much dough, I usually can make 3 loaves. We've also used the dough to make deep-dish pizza crusts (yummy!) and we can get 2 large pizzas from that much dough.
