This is a popular salad in Georgia. A family friend, Bobbie Jean Ozburn, first took it to a Monticello Woman’s Club luncheon and it became known as “That Woman’s Club Grape Salad.” There are a lot of versions of this salad out there. It’s called a salad, but it’s really more of a dessert.
Wash the grapes and dry thoroughly with paper towels. Put the dry grapes in a large bowl. In a separate bowl, stir the cream cheese until it is smooth. Add the sour cream, granulated sugar, and vanilla. Mix well. Pour this mixture over the grapes and toss together until all grapes are coated. Pour the grapes into a 9 × 12-inch pan. Refrigerate overnight.
Just before serving, sprinkle with the brown sugar and pecans.
