In a sauce pan or in the microwave, heat your water until it is warm to the touch.
In your mixing bowl, add water, milk, olive oil & sugar. Mix well
Add your sourdough discard, and mix.
Next, add 2 cups of your flour & salt.
Work until a shaggy dough forms.
Dump dough out onto a clean floured work surface, and knead. Adding in more flour as needed, if the dough is too sticky.
Once you have kneaded for a couple of minutes, and dough has become smooth, place dough into lightly oiled bowl.
Cover bowl and allow to proof for 4-6 hours, in a warm spot. This timeline will vary depending on the state of the sourdough starter you used. If it was flat discard, you will want to leave it for 6 hours, if it was active and bubbly you can shorten the proof closer to 4 hours.
Once dough has been left for 4-6 hours, preheat your oven to 350℉.
Grate 1 cup of cheese, and get pepperoni sticks ready (I like using about 4" sticks)
Take dough out of your bowl, and roll it out, into a rectangle. You want it to be about 1/2 inch thick.
Evenly space pepperoni sticks on dough, and cut dough into rectangle around each pepperoni stick, leaving enough dough so that you can roll it around the stick.
Place them on a baking tray, and top with cheese. I like to press the cheese onto them a bit so that it stays in place.
Bake for about 15-17 minutes, until they start to lightly golden on the edges.
Cool & enjoy!
