Garlic and Cheese Popovers

This was a really easy quick supper.  It would also make a good side dish.  All of my kids ate it and seemed to enjoy.  I would make this recipe again.

Ingredients
Butter:
1/2 cup (1 stick) unsalted butter, at room temperature
2 tablespoons anchovy paste
1 tablespoon chopped chives
1 1/2 teaspoons fresh lemon juice
1/2 teaspoon lemon zest
Kosher salt and freshly ground black pepper, optional
Popovers:
Vegetable oil cooking spray
6 large eggs, at room temperature
5 cloves garlic, minced
2 cups whole milk, at room temperature
1 1/4 cups (3 ounces) finely grated Asiago cheese
1/4 cup (1-ounce) shredded sharp Provolone cheese
1 1/2 cups all-purpose flour
2 teaspoons kosher salt
1/2 teaspoon freshly ground black pepper
1/4 cup chopped flat-leaf parsley
Directions


Butter: In a small bowl, mix together the butter, anchovy paste, chives, lemon juice, and lemon zest until smooth. Season with salt and pepper (if using), to taste.

Popovers: Put an oven rack in the center of the oven. Preheat the oven to 400 degrees F. Spray a 12-count muffin or popover pan with vegetable oil cooking spray. Set aside.

In a blender, add the eggs and garlic. Blend on medium speed untilfrothy, about 15 seconds. Add the milk and the cheeses and blend until smooth. Add the flour, salt, pepper and parsley. Blend on medium speed until incorporated. Pour the batter into the muffincups, filling each cup to within 1/4-inch of the top. Bake, without opening the oven door, until puffed and golden, about 30 to 35 minutes. Remove the popovers from the oven and serve with the anchovy butter.
