For the melon champagne cold bowl, cut melons in half in a zig-zag shape and cut out the seeds with the help of a spoon. Cut out small balls from the flesh with a cookie cutter (set these aside as an inlay).
Carefully scrape out the remaining pulp with a spoon, leaving the melon halves whole.
Add powdered sugar, pulp, sparkling wine, vanilla sugar, juice and zest of one lemon and ice cubes. Blend finely until you have a frothy soup.
Gently stir in the remaining sparkling wine, leaving the carbonated beads. Pour into the hollowed out melon halves.
Arrange the melon balls set aside, fresh strawberries, and a scoop of Maracuka ice cream in each, decorate with mint leaves, and serve with the melon and sparkling wine cold dish.
