Roughly chop the chocolate coating and melt it on a hot water bath, fill it into a freezer bag and cut off a small corner. Spray strips onto the meringue bowls and let them dry for about 30 minutes.
Spray ornaments on baking paper with the remaining couverture and let them dry as well. Meanwhile drain the peaches and dice them finely. Wash the mint, dab dry and pluck leaves from the stalks, except for a few for decoration.
Cut the mint into fine strips. Wash the limes, grate them dry, peel them very thinly and cut the peel into fine strips. Mix peach, lime peel and mint. Squeeze 1 lime and add the juice to the salsa.
Add tequila and brown sugar and mix everything together. Pour the salsa into the meringue bowls. Decorate with remaining mint and chocolate ornaments.
