Caramel is when sugar is heated and becomes a liquid. As it continues to cook it becomes golden brown and has an intense, deep flavour from the caramelization of the sugar.
These upside down apple Caramel cakes have been made in two different ways.
Another tweak of mine to the classic Ryzogalo (rice pudding). I added caramel to the pudding, this time the rice was cooked in milk until soft and then the pudding was baked in the oven.
