Ingredients
1 head cauliflower
vegetable oil
1 1/2 c. all-purpose flour
salt
3/4 c. cold club soda
1/2 c. cold sparkling white wine
1 large egg white
1 medium zucchini
1/2 lb. cremini mushrooms
1 red apple
Preparation
Step 1Set a steamer basket over 1/2-inch of water in a medium saucepan. Cover and bring the water to a boil. Add the cauliflower, cover, and steam over moderately high heat until crisp-tender, about 1 minute. Transfer the cauliflower to a plate and pat dry.Step 2In a large saucepan, heat 2 inches of vegetable oil to 400 degrees F. Line a large rimmed baking sheet with paper towels. In a large bowl, whisk the flour with 1 teaspoon of salt. Add the club soda and sparkling wine and whisk until the batter is smooth. In a medium stainless steel bowl, beat the egg white until firm peaks form. Fold the egg white into the batter.Step 3Working in batches, dip the zucchini, mushrooms, and apple in the batter, letting any excess batter drip back into the bowl; add to the hot oil and fry, turning once, until golden brown, about 2 minutes per batch. Using a slotted spoon, transfer the fritto misto to the paper towels and season with salt. Serve right away.
