Preheat oven to 350 degrees F.

Place flour, salt, paprika and garlic powder in the bowl of a food processor. Whir briefly to mix.

Add butter and pulse to pea-sized pieces.

Add the starter, cheeses, and 2 tbsp water. Pulse to combine well. Add more water 1 tbsp at a time if needed to form a dough.

Dump out of the bowl, and form into a ball. Wrap with bees wrap or plastic and refrigerate/chill 30 minutes.

Roll out very thin. Place on a parchment-lined baking sheet. Trim any edges to fit the dough to the sheet. Save scraps to re-roll.

Bake 5-7 minutes. Remove from oven and score with a ravioli cutter or pizza wheel. Return to the oven and bake 15 minutes.

Remove and let sit 5 minutes, check for preferred crispiness. Return to the oven for a few minutes if not crispy enough.
