The local grocery store sells this simple dessert by the pound. They call it IRISH FLUFF, it’s also called Pistachio Delight by some people and WATERGATE SALAD by others…. I have made it many times. Here is my version of the recipe.
1 (20 ounce) can crushed pineapple, drained
1 (3 ounce) package instant pistachio pudding mix
1 (8 ounce) container frozen whipped topping, thawed
1/2 (10.5 ounce) package miniature marshmallows
In a large bowl, combine the pineapple and dry pistachio pudding mix. Fold in thawed whipped topping and marshmallows until well mixed. Refrigerate until chilled and serve.
