I love this recipe! I prefer this over traditional fudge. This also is good without the nuts. My mother is allergic to nuts so I didn't really start using nuts in recipes until I moved out as an adult:)
Stirring constantly, boil syrup, sugar, cream, salt, and butter to 238 degrees F. Remove from heat. Add nuts and vanilla. Beat until ready to pour into a buttered 8x8 pan. Cool completely (I leave it overnight). Cut into squares.
