<human>:  How do I cook a homemade pizza from scratch?
<bot>: To make a homemade pizza from scratch, you will need all-purpose flour, active dry yeast, salt, sugar, olive oil, and warm water. Begin by mixing the yeast, sugar, and 1/2 cup of warm water in a bowl and let it sit for about 5 minutes until the mixture is foamy. In a separate bowl, mix the flour and salt, and then slowly pour in the yeast mixture and the remaining warm water until a dough forms. Knead the dough for about 5 minutes until it is smooth and elastic. Lightly lightly oil a clean bowl, then place the dough inside, cover it with a damp cloth, and let it rise in a warm spot for about 1 1/2 hours. After the dough has risen, turn it out onto a lightly floured surface and roll it out into a 12-15 inch circle. Place the dough onto a greased baking sheet and top it with your favorite toppings. Bake the pizza at 400°F for 15-20 minutes, or until the cheese has melted and the crust is golden brown. Enjoy!
