Recipes are funny things. They don't always come from where you'd expect them to come from. This particular caramel recipe came from a pharmacist my dad used to work with in Pryor, Montana. She loved to take our blood. She was a goof ball and kind of creepy as she showed us how she drew out blood, separated it, and tested it under her high powered microscope. However, along with being a kind of vampire in our 8, 9, and 12 year old minds, she also had a great recipe for dark caramels. I dug this recipe out Monday and gave it a go. It was the first time we've made it with a thermometer. Man alive, did that make a difference! This is the best caramel I have ever had I think. It's not hard to make at all. Just be sure to use a large enough pan and don't forget to keep stirring!
3 cups packed brown sugar
1 can Sweetened Condensed Milk
1 cup light Karo syrup
Melt butter to oil. Add the rest of the ingredients and stir constantly until it reaches 240* (about 22 minutes after it starts to boil). Pour into buttered 8x8 baking dish to cool. After it is cooled, remove from pan and cut into squares. I'm not a perfectionist, so my caramels are not really the same sizes at all, but about 1"x1" is about right. Wrap each piece in wax paper. Enjoy!
