I melted caramel in a double broiler. Which is a fancy name for my version...a little pot in a bigger pot of boiling water. This is so the caramel won't burn. Remove the core and stick a wooden apple stick or skewer through the top. Dip the apples in caramel and quickly roll in nuts. (I used hazelnuts) I placed mine on a cookie sheet and cooled them for a bit. Then drizzled chocolate and decorated with sprinkles. The toppings are endless! Have fun!
