Wash the Zucchini flowers under fresh water.
Gently open the petals of each flower and insert 2 capers and 1 cube of mozzarella.
In a bowl, prepare the pastella (batter) by mixing: flour, eggs, garlic, mint, cheese and water.
Dip the flower in the pastella and fry in hot oil.
Fry the flowers on both sides until they turn golden.
Serve immediately.
