Mix all ingredients in a 3-4 quart cast iron dutch oven.
Swirl pan to keep ingredients moving in the pan. Cook to softball stage 235º – 245º on a candy thermometer or when tested in a cup of cold water. Remove from heat and beat with a wooden spoon until creamy and ready to spread.
No thermometer? Do the cold water test:
Take a some of the caramel and drop it into a bowl or cup of cold water. Give it a few seconds to cool. Fish around in the bowl or cup of cold water and try to retrieve the caramel and make a little ball with it.
If you stick your fingers into the bowl, pull out a gooey mess and you can’t do anything but smear the caramel, you need to boil the caramel some more. There is still too much water in your caramel and the concentration of sugar is too low. The caramel may even form little threads in the water, but if you cannot get the threads to form into a ball, you have some more boiling to do. Voir moins
