Laura's Caramels

Another yummy one...

Caramels
½ lb butter
2 cups light corn syrup
2 cups sugar
2 14-oz cans sweetened condensed milk
½ cup flour (mixed with about ½ cup of the condensed milk)
2 tsp vanilla

Measure and set out all ingredients before you start. Have a spatula and a long handled wooden spoon or scraper handy.
Melt butter in large, heavy saucepan/pot (non-stick works best). Add corn syrup and sugar. Bring to a boil on medium heat, stirring constantly, and boil for 5 minutes. Take pan off burner (don’t turn it off) and stir in 1 ½ cups of the milk, then add the flour/milk mixture. Stir well and return pan to burner. Boil over medium heat, stirring constantly until mixture darkens and reaches a medium hard ball (240). Remove from heat, stir in vanilla. Turn into buttered 9x13 glass pan. Cool. Cut into bite-sized pieces with buttered knife. Wrap in small pieces of wax paper.
