My holiday standard. Raw spanish peanuts can be bought in bulk at Sprouts to cut down on the cost. (I use about 40 pounds of nuts.)
2 cups sugar
1 cup Karo light syrup
2 cups raw Spanish peanuts
2 Tbsp. butter
2 tsp. soda
1 tsp. vanilla
½ cup water
Bring water to a boil on med/high heat. Remove and add sugar and karo syrup.
Bring to a boil. Add peanuts. Stir constantly. Put in candy thermometer and cook to 295 degrees on medium to medium/high heat. When 295 degrees remove from heat and add butter and vanilla. Quickly stir in soda. Pour out onto two buttered cookie sheets. Break into pieces when cooled.
