1Prepare a 4x8 loaf pan by lining with foil, butter the bottom of pan and up the sides 2". Set aside.
2In a 2 quart saucepan, mix sugar, salt and sour cream. Cook over medium heat to softball stage, 235 degrees, stirring constantly. It may spit and sputter, be careful.
3Remove from heat, add butter and beat until fudge starts thicken and loose it's gloss. Quickly stir in nuts, if desired and pour into prepared 4x8 loaf pan.
Allow to completely cool then cut into 1" squares and enjoy!!!
Store in refrigerator in an air tight container. Freezes well.
4*nuts- my favorite is pistachios, then pecans, my dads favorite is walnuts and my grandma's favorite is black walnuts...so the choice is yours!
*I've added dried cherries to this before, add with the nuts.
*Also, I've used light sour cream and it's turned out just fine.
*Also, when time to beat, I use a hand held electric mixer, my mom has always beat by hand, so either method works just fine, though if using a mixer, it cools much faster, so watch it closely as you want to pour it as soon as it starts to loose it's gloss. If you wait to long it will harden and you won't be able to pour it, let alone spread it in the pan. :)
