Heat water in a large pot to 170 degrees. Place the curd in a mixing bowl and cover it with hot water (leave some in the pot since you'll need fresh hot water again later). Work the curd with a wooden spoon toward you until it melts into one large ball, about 2-3 minutes. Drain the milky water and cover with fresh hot water.
Add 1 teaspoon of kosher salt to every pound of curd used. Stretch the mozzarella, pulling but not tearing it for about 3-4 minutes. Shape the mozzarella as desired and serve warm topped with extra-virgin olive oil, fresh basil, sliced tomatoes, and roasted red peppers.
