FRIED ONION RINGS

Pour peanut oil into a wide deep pot to a depth of 2” and heat over medium-high heat until temperature reaches 365 on a candy thermometer. Meanwhile, whisk together flour and cups prosecco or other sparkling wine in a large bowl until batter is smooth; season to taste with salt and freshly ground black pepper. Slice large peeled vidalia or other sweet onions into 1”-thick rounds, then separate into rings. Working in small batches, coat onion rings in batter, then use a fork to transfer rings one at a time to hot oil, and deep-fry, turning often, until golden and crisp, 2-3 minutes per batch. Transfer onion rings with a slotted spoon to paper towels to drain. Season to taste with salt.
