1/2 lb real butter (2 sticks),
2 cups sugar,
2 cups light Karo syrup,
1/4 teaspoon salt.
Put all these in a deep pan and melt together on medium high heat stirring constantly until the mix bubbles boiling.
Then sloooowwwly add in 1 can evaporated milk, so it keeps boiling.
Boil at 245 to 250 degrees or you can do what I do and just stir constantly on high heat until it turns a light caramel color.
Then, take from heat and stir in 1 teaspoon vanilla quickly.
Pour right away into a well buttered pan and let cool. I do it at night and cut them in the morning with a butter knife and wrap separately in wax paper.
They taste GOOD!!! Good luck!
