This recipe is for making sourdough discard sandwich bread in a bread maker from start to finish. You will need to consult your bread machine's instruction booklet for program times.
Add all of your ingredients into the pan of your bread machine. It's easier if you add the liquid first and then the dry ingredients on top. It makes it easier for the bread maker to knead the dough.
Depending on your bread machine and how quickly you want your bread, select a setting for your loaf. You can use the full program or the express program. If you are able to select the size of the loaf, go for "extra large" and set the crust to dark so you get a nice crunchy crust.
If you can, remove the paddle from your pan before the bread starts to bake - this will ensure you don't get the hole in your bread where the paddle sits.
Once your sourdough discard loaf has finished baking, remove from the pan as soon as possible to avoid it sweating. Place the bread back into the machine with the lid ajar for air flow to avoid a wrinkled crust.
Notes
Remember that you can look inside while the machine is going. Don't be afraid to use a spatula to mix in the flour that's on the sides of the pan or to rearrange the dough if it's not sitting correctly (you can read all the tips in the post above).
