Whisk flour, salt, and yeast in a medium bowl. While stirring with a wooden spoon, gradually add ¾ cups water; stir until well incorporated. Mix dough gently with your hands to bring it together and form into a rough ball. Transfer to a large clean bowl. Cover with plastic wrap and let dough rise at room temperature in a draft-free area until surface is covered with tiny bubbles and dough has more than doubled in size, about 18 hours.

Transfer dough to a floured work surface. Gently shape into a rough rectangle. Divide into 16 equal portions – they will be quite tiny. Working with 1 portion at a time, gather 4 corners to center to create 4 folds. Turn seam side down and mold gently into a ball. Dust dough with flour; set aside on work surface or a floured baking sheet. Repeat with remaining portions.

Let dough rest, covered with plastic wrap or a damp kitchen towel, until soft and pliable, about 1 hour.

During the last hour of dough’s resting, prepare oven: arrange a rack in middle of oven and preheat to its hottest setting, 500°–550°. Working with 1 dough ball at a time, dust dough with flour and place on a lightly floured work surface. Gently shape dough into a small 3″ disks.

Arrange dough disks on a lightly oiled baking sheet; top with desired toppings. Bake pizzas until bottoms of crusts are crisp and tops are blistered, about 8-10 minutes. Transfer to a work surface to slice, if desired.
