In a small bowl, combine the warm water, sugar, and yeast. Stir gently to dissolve the sugar and yeast.Let the mixture sit for about 5-10 minutes, or until it becomes frothy and bubbly. This indicates that the yeast is active.
In a large mixing bowl or the bowl of a stand mixer fitted with a dough hook attachment, combine the flour and salt.Make a well in the center of the flour mixture and pour in the activated yeast mixture and olive oil.
Mix the ingredients together until a dough starts to form.If using a stand mixer, knead the dough on low speed for about 5-7 minutes, or until it becomes smooth and elastic.If kneading by hand, transfer the dough to a lightly floured surface and knead for about 8-10 minutes until smooth and elastic.
Place the dough in a lightly greased bowl, turning to coat all sides with oil.Cover the bowl with a clean kitchen towel or plastic wrap.Let the dough rise in a warm, draft-free place for about 1 to 1 1/2 hours, or until it has doubled in size.
Once the dough has risen, gently punch it down to release the air.Divide the dough into two equal portions for two medium-sized pizzas, or leave it whole for one large pizza.On a lightly floured surface, shape each portion into a smooth ball. Cover with a clean kitchen towel and let it rest for about 15-20 minutes.
After resting, roll out each dough ball into a circle (or a heart shape for Valentine's Day!) to your desired thickness.
Follow the instructions in the heart-shaped pizza recipe above to add your desired sauce, cheese, and toppings.Bake the pizza according to the instructions until the crust is golden brown and the toppings are bubbly and heated through.
