Wash the sushi rice several times until the water is clear. Cover and cook in 600 ml water at low heat for 18-20 minutes. Put the rice in a bowl and season with the ready-mix. Let the rice cool down while stirring.
Clean the chilli, cut lengthwise, remove seeds, wash and finely chop. Stir into the mango sauce. Cut mozzarella lengthwise into approx. 1 cm wide oblong strips. Peel mangoes and cut them into thick slices from the stone.
Then also cut into strips about 1 cm wide. Place 1 nori leaf on a bamboo mat with the smooth side down, spread approx. 1⁄6 rice on top. Leave 2-3 cm free upwards. Lay the mozzarella and mango on the lower half lengthwise, approx. 1⁄6 each.
Sprinkle with 1 tablespoon mango sauce. Use the bamboo mat and a lot of dexterity to roll it up firmly. Prepare 5 more rolls in this way. Cut the sushi rolls into slices. Serve with sushi ginger, cress, soy sauce and wasabi.
