Vegetable tempura coats broccoli, courgette and carrot in a thin, crisp batter and fries them quickly. The source mixes ice water with sparkling water; this version keeps the batter very cold and slightly lumpy, since overmixing develops gluten and makes the coating heavy. Cut vegetables into similar, thin pieces so they cook in the short frying time. Work in small batches and let the oil recover its temperature between them. Serve immediately with a simple soy dipping sauce. Wash and dry vegetables thoroughly. Cut into similar, thin pieces. Heat oil in a deep heavy pan to 175°C (350°F); do not fill the pan more than one-third full. Whisk flour, cornstarch and salt. Pour in cold sparkling water and stir briefly; small lumps are fine.
