I have a question about step 5 on the recipe "Jim Lahey's No-Knead Pizza Dough" from Genius Recipes. It says:
"Switch the oven to broil for 10 minutes. With the dough on the peel, spoon the tomato sauce over the surface and spread it evenly, leaving about an inch of the rim untouched. Distribute 10 to 12 hunks of mozzarella (about 7 ounces) on top." Switch the oven from ??? to broil? Off? or was oven preheated? Thanks!
