easiest baked mac-and-cheese

INGREDIENTS

• 2 tablespoons butter
• 1 cup cottage cheese (not low fat)
• 2 cups milk (not skim)
• 1 teaspoon dry mustard
• Pinch cayenne
• Pinch freshly grated nutmeg (I skipped this)
• 1/2 teaspoon salt
• 1/4 teaspoon freshly ground black pepper
• 1 pound sharp or extra-sharp cheddar cheese, grated (I’m a big fan of Cabot extra-sharp, in the purple wrapper)
• 1/2 pound elbow pasta, uncooked.
