My dad calls this stuff "The only good thing to come out of the Reagan White House." The recipe was created by Reagan's first White House chef.
White House Nut Brittle
Spread 1 to 1-1/2 c. salted mixed nuts (with no peanuts) onto a buttered cookie sheet.
1 c. sugar
1/2 c. butter
1/4 c. molasses
1 T. cider vinegar
2 T. water
Bring all ingredients to a boil in a 3 quart saucepan. Boil covered for 2-3 minutes. Uncover, clip on candy thermometer, and cook over moderate heat at a slow boil to 290 degrees. Pour hot syrup over nuts. Allow to cool. Enjoy.
I pretty much cook it by smell. When it smells like it's burning, it's done.
