1. Make the dough: Whisk flour, salt, and yeast in a medium bowl. While stirring with a wooden spoon, gradually add 3 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 or tea towel and let dough rise at room temperature (about 72°) in a draft-free area until surface is covered with tiny bubbles and dough has more than doubled in size, about 18 hours (time will vary depending on the temperature in the room).
2. Transfer dough to a floured work surface. Gently shape into a rough rectangle. Divide into 6 equal portions. 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.
3. Wrap each dough ball separately in plastic wrap and chill. Unwrap and let rest at room temperature on a lightly floured work surface, covered with a light dusting of flour for about an hour or two before shaping. DO AHEAD: Can be made 3 days ahead.
4. To Make the Pizzas: Pull out a pizza round from the fridge one hour before you plan on baking. Dust dough with flour and place on a floured work surface. Preheat oven to its hottest setting, 550°F. Gently shape dough into a 10″–12″ disk handling it as minimally as possible. Arrange dough disk on parchment-lined baking peel; top with minced anchovy and garlic and a drizzle of olive oil. Pile on the shaved zucchini. Note: It’s ok to add more than you think feels right here because the zucchini shrinks down a lot. Top with roughly cubed mozzarella or burrata. Sprinkle with nice salt. Drizzle with a splash more olive oil.
5. Bake pizza until top is blistered, about 5 minutes. Transfer to a work surface. Top with basil leaves. Slice and serve.
