Preparation

• Position a rack in the lowest part of the oven. Put a 6-cup popover pan on a rimmed baking sheet on the rack. Heat the oven to 400°F. In a small saucepan over medium-high heat, warm the milk until small bubbles form around the edges. Using a fine-mesh strainer, sift the flour and salt onto a sheet of wax paper or parchment.

• Remove the popover pan from the oven and spray with cooking spray. Fill the cups about three-fourths with batter, and sprinkle each with 1/2 oz. of the cheese (about 2 Tbs.). Return the pan to the oven, and bake for 20 minutes. Reduce the oven temperature to 350°F. Continue baking until the popovers are browned and puffed, about 25 minutes more; do not open the oven while the popovers are baking.
• Invert the pan and remove the popovers. Serve immediately. Using a paper towel, wipe out the excess fat from the popover cups. Heat the pan in the oven for 5 to 10 minutes, then spray again with cooking spray. Fill with the remaining batter and cheese and bake as directed above.
