I got this recipe from Food.com. I was looking for something different to add to a family get together. This makes a big amount but it's heavely and the longer it stays in the fridge the better it taste. This is one dish I'm asked over and over to bring.
2Mix sour cream, cream cheese, white sugar and vanilla by hand until blended.
3Stir grapes into mixture, and pour in large serving bowl.
4TOPPING: Combine brown sugar, and crushed pecans. Sprinkle over top of grapes to cover comletely. Chill overnight.
5Some people leave the topping off. This makes it less sweet, but it is wonderful with it and the longer it sets the more the brown sugar and nuts melt down through it. Also you can make the topping and set it aside and let guests add the topping to each helping as they dish it up.
