Cut the pulp of watermelon into portioned pieces 2x3 cm, roll in flour. Mix flour, starch, egg, sugar, add a little water.
Add ice to the resulting mass and mix again. Dip slices of watermelon in batter and deep-fry at a temperature of 150–170ºС.
Place the fried pieces on a paper towel to absorb excess oil. Sprinkle with powdered sugar when serving. You can drizzle with caramel sauce if you like.
