Mix milk, sugar, syrup and butter together in a 5 qt pan.   Cook and stir over medium heat until forms a soft ball in cold water.   Approximately 1 1/2 hours.   Remove from heat, add vanilla, beat until it loses it's gloss.   Add nuts and out put onto a buttered jelly roll pan.   Cut into squares when cool!
Takes a long time to beat after you remove from heat and will get very hard to stir but if not beat long enough will not set up!
