We had this at our super saturday and it was amazing, so I thought i would share.
1 can sweetened condensed milk
1 cup Karo Syrup
1 stick butter or margarine
2 cups brown sugar
Melt butter over med/high heat, add syrup and brown sugar and bring to a boil, boil 1 min. add milk, bring to a boil, remove from heat.
Slice up apples and pour lemon juice on the top so they don't turn brown, then just dip in the caramel. You can add a little extra by having nuts or chocolate sprinkles to dip in too. This was so good, everyone loved it.
