I do not have a bread machine. Doing sourdough the “old style” by hand.
The dough made a day before baking.
But thanks for the offer.
I only use three ingredients. Flour, water and salt.
Flour, water, and salt makes a salty hard paste for sure. No yeast? Well, salt does kill yeast, so I understand that.
Even handmade, try this: 3 cups bread flour, 1.5 tbls olive oil, 1.5 tsp salt, 9 oz beer (any kind) warm and flat is best, 2 tsp yeast (though I'm not sure the difference between bread machine yeast and dry packaged), a tsp of onion powder, a tsp of garlic powder, and a tbls oregano. Mix and knead it any way you like. When it rises, bake. I can't tell you how to bake it, I use the machine.
Try it and tell my you don't like it better...
