Beer Batter Cauliflower - cooking recipe

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

Preparation

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.
