Ingredients

• 3/4 cup plus 2 tablespoons beer (not dark)
• 1 cup all-purpose flour
• 3/4 cup finely chopped fresh parsley leaves
• 3/4 teaspoon salt plus additional for sprinkling rings
• 1 large onion (about 3/4 pound)
• vegetable oil for deep-frying
• Accompaniment: salsa verde if desired

Instructions

1. In a bowl whisk beer into flour until batter is smooth and whisk in parsley. Let batter stand 30 minutes and stir in 3/4 teaspoon salt.
2. Cut onion crosswise into 1/2-inch-thick slices and separate slices into rings.
3. In a large deep skillet heat 1 inch oil to 380°F. Working in batches of 4 or 5 onion rings, drag rings through batter to coat completely, letting excess drip off, and fry, turning, until golden, about 1 to 2 minutes. With tongs transfer rings as fried to paper towels to drain and season with additional salt.
4. Serve onion rings with salsa verde.
