CARROT, ZUCCHINI, AND LEEK FRITTERS

Steps:

• In a colander, toss zucchini with 1/2 teaspoon kosher salt. Let drain 10 minutes, then squeeze dry. Transfer to a large bowl. Heat oil over medium in a medium heavy-bottomed skillet, such as cast iron. Add leek and cook, stirring occasionally, until tender but no color has developed, about 5 minutes. Transfer to bowl with zucchini and let cool completely. Stir in carrots, potato starch,1 teaspoon kosher salt, and 1/4 teaspoon pepper to combine, then fold in egg.
• Pour a scant 1/2 inch oil into skillet. Heat over medium until oil shimmers and bubbles form instantly around a breadcrumb dropped in (350°F on a deep-fry thermometer). Working in batches, form mixture into golf-ball-size rounds; carefully drop into oil and flatten slightly.
• Fry, flipping once and adjusting heat as needed to maintain a level temperature, until crisp and golden brown, about 5 minutes. Drain on a wire rack set over a rimmed baking sheet, then sprinkle with flaky salt; keep warm in a preheated 200°F oven while frying the rest. Serve warm, with dipping sauces.
