Ingredients

  • 1 quart vegetable oil, or as needed
  • 1 1/3 cups all-purpose flour
  • 1/4 cup freshly grated Parmesan cheese
  • 1 tablespoon chopped fresh parsley
  • 1 teaspoon salt
  • 1/4 teaspoon garlic powder, or more to taste
  • 1 pinch cayenne pepper, or more to taste (optional)
  • 1 1/4 cups flat beer
  • 2 egg yolk, beaten
  • 1 tablespoon vegetable oil
  • 2 egg whites
  • 1 head cauliflower, cut into florets

Method

  • Preheat oven to 300 degrees F (150 degrees C).
  • Heat 1 quart vegetable oil in a deep-fryer or large saucepan to 375 degrees F (190 degrees C).
  • Combine flour, Parmesan cheese, parsley, salt, garlic powder, and cayenne pepper in a large bowl.
  • Whisk beer, egg yolk, and 1 tablespoon vegetable oil in a small bowl.
  • Pour beer mixture into flour mixture; stir to form a batter.
  • Beat egg whites until foamy in a large glass or metal mixing bowl; continue to beat until medium peaks form. The tip of the peak formed by the egg whites should curl over slightly when you lift the whisk or beat straight up.
  • Fold egg whites into batter, a few tablespoons at a time.
  • Toss cauliflower in the batter until fully coated.
  • Deep fry small batches of battered cauliflower in the hot oil until golden brown, 3 to 5 minutes. Drain on a paper towel-lined oven-proof plate. Keep warm in the preheated oven.
