I did get my fluffy lime pie made the other day. Very yummy and super easy. I made it from a Bisquick recipe where it had me make the crust. But I almost think a graham crust would be better.
Beat 1 can (14oz.) sweetened condensed milk with 1/2 cup lime or key lime juice in large bowl with electric mixer on medium until smooth and thickened. Fold in 1 container (8oz.) whipped topping and 1 TBSP grated lime peel. Cover and refrigerate 2 hours or until set. Garnish with lime slices if like.
