In a large stainless steel bowl, mix the flour, sugar, and salt until well combined.
Place the sticks of butter in the bowl and coat them on all sides with the flour mixture.
Using a bench scraper, cut the butter into 1/2-inch cubes. Work quickly to separate the cubes with your hands until they are lightly coated with flour.
Switch to a pastry blender and begin to cut the butter with one hand while turning the bowl with the other. Continue until the largest pieces are the size of peas and the rest of the mixture resembles Parmesan cheese.
Add the water-vinegar mixture all at once. Use a bench scraper or your hands to mix until you can't see visible liquid pools. Scoop up as much of the mixture as you can and press it down onto the rest of the ingredients. Rotate the bowl a quarter-turn and repeat. Scoop, press, and turn until the mixture forms one cohesive mass. This will take several minutes to come together, don't be tempted to add more water.
Remove the dough from the bowl, place it on a lightly floured counter, and use your bench scraper to divide it into two equal pieces. Gently pat each into a 2-inch thick disc, quickly sealing any broken edges before wrapping them tightly in a double layer of plastic wrap. Refrigerate the dough for at least 2 hours or, ideally, overnight.
