Combine flour, pepper, and salt in a mixing bowl. Stir to combine.

Pour in white wine and olive oil. Mix until dough comes together. Knead until smooth, about 3 minutes.

Wrap dough in plastic wrap and let rest at room temperature for 30 minutes.

Cut rested dough into 4 pieces, then roll each into ropes. Cut ropes into smaller pieces, twist into rings, and seal ends.

Preheat oven to 400°F (200°C) and line a baking sheet with a silicone mat.

Boil dough rings in water until they float, then transfer to a towel-lined plate.

Transfer boiled rings to baking sheet, sprinkle cheese on both sides, and bake until golden and crunchy, about 25-30 minutes.
