Cool the cheesecake completely. While it cools down, you can make a decoration of jelly (neutral gel) and limes.
Cut the lime into thin slices. Melt the sugar in a frying pan and smear the lime with icing.
Spread the cooled (can be cooled on baking paper) caramel with lime slices over the surface of the cooled cheesecake (it should be kept in the refrigerator for 3 hours beforehand) and pour neutral jelly (gelatin) to cover the cakes, cooking it as indicated on the package. Return to the refrigerator so that the gel freezes.
