Preheat your oven to a sizzling 500°F.

Combine the flour, salt, sugar, and rosemary in a bowl. Whisk until combined.

Stir in the water and olive oil until fully combined.

Turn out the dough onto a lightly floured piece of parchment paper.

Roll the dough out until it’s about 1/8th of an inch thick.

Trim the edges if desired.

Cut the dough into squares using a pizza cutter and brush with water. Sprinkle with sea salt.

Transfer the dough, still on the parchment paper, onto a baking sheet and reduce the heat to 425°F.

Bake them for 12–17 minutes or until golden and crisp.
