With tomato sauce and torn fresh mozzarella, the toppings are simple on this squash blossom pizza to let the flowers be the star of the pie.
2/3 cup warm water
1/2 teaspoon dry active yeast
1/2 teaspoon granulated sugar
1 teaspoon olive oil plus more for bowl and brushing pizza
1–1/2 cups bread flour plus more for work surface
1/2 teaspoon kosher salt
3/4 cup tomato sauce
4 ounces fresh mozzarella, torn
6 squash blossoms, de-stemmed and petals separated
For the dough, combine the water, yeast, sugar and olive oil and let stand for 5 minutes until foamy. In a large bowl, mix together the flour and salt. Add the wet ingredients to the dry and stir until it forms a shaggy dough.
Turn the dough onto a lightly floured work surface and knead for 10 minutes until the dough is smooth and elastic. (Alternatively, the dough can be mixed in the bowl of a stand mixer using a dough hook.)
Gather the dough into a ball, transfer to an oiled bowl and cover. Place the bowl in a warm spot to allow the dough to rise until it has doubled in size, about 2 hours.
Preheat a gas or charcoal grill on medium high heat.
On a lightly floured work surface, roll out the dough in a 12 inch circle. Place the dough directly on the grates and grill for 3 minutes with the lid closed until the crust has grill marks and has puffed up. Turn over the crust and grill for an additional 2 minutes.
Remove the crust from the grill. Spread the tomato sauce leaving a 1/2-inch border at the edge. Arrange the mozzarella and squash blossoms on top. Put the pizza back on the grill for a couple minutes to let the cheese melt. Slice and serve right away.
