Herb butter
In a small bowl, mix 1/2 c. water with the yeast and allow to bloom for 5 minutes.
Combine 1/2 c. water, olive oil, sugar, and salt in mixing bowl, then add the bloomed yeast mixture. Stir in 1 c. of flour at a time, then need until smooth. Allow to rest 10 minutes and give a final knead. Shape into a large rectangle. Cut lattice prongs, add toppings, and weave lattice (alternatively, shape into 2 circles, add toppings, and fold over and crimp).
Melt butter with herbs on stovetop, then brush onto calzone(s). Bake at 500°F for 10-12 minutes.
