Calzone Dough

2 cup lukewarm water
1 1/2 tablespoons yeast
2 teaspoon salt
1 1/2 tablespoon sugar
6 cups flour, plus extra for dusting
2 tablespoon oil

In a bowl, combine the water, yeast, salt and sugar, and stir to dissolve. Set aside for 15 minutes, then add the flour, and mix until smooth. Turn the dough out onto a floured work surface, and knead for 10 minutes, adding more flour if necessary. The dough should feel smooth and elastic. Lightly oil a bowl, and place dough inside. Let rise in a warm place until doubled in size, about 1 hour. Quarter the dough, and shape each piece into a ball. Cover, and let rise another 15 minutes. Makes enough dough for 8 calzones.
