Instructions

1. Preheat oven to 450 degrees. In a bowl, dissolve yeast and sugar in warm water. Let stand until creamy. This should take around 10 minutes.
2. Stir in salt, flour and oil. Beat until smooth. Let stand for 5 minutes.
   Turn dough out onto a lightly floured surface and pat into a round pizza like object. Transfer crust to a lightly greased pizza pan or dusted with cornmeal.
3. Bring Cavit merlot wine with sugar to a boil in a small heavy saucepan over moderate heat, stirring until sugar is dissolved, then boil, uncovered, until reduced to about 1 tablespoon, about 5 minutes. Add grapes to saucepan and stir gently to coat with syrup, then transfer to a bowl. Add cheeses and pepper to bowl, then stir to combine.
4. Assemble on top of pizza with fresh basil and prosciutto leaving a 1-inch border.
5. Bake in preheated oven for 15 to 20 minutes, or until golden brown. Let baked pizza cool for 5 minutes before serving.
