Watergate Salad vs Ambrosia
The difference between watergate salad vs ambrosia salad comes from the ingredients, as they are both no bake fluff desserts made with Cool Whip. Watergate salad is made with pudding while ambrosia is not. Watergate salad is green and pistachio flavored, while ambrosia salad has a vanilla base. Ambrosia salad is made with lots of fruits: mandarin oranges, pineapple, and maraschino cherries, while watergate is made with just pineapples.

Pistachio Fluff Fruit Salad Ingredients
- Pineapple – use canned, crushed pineapples and be sure to keep the juices—we need it to hydrate the instant pudding mix!
- Pudding mix – use instant pistachio pudding mix. We’re gonna make this pistachio fluff dessert recipe quick by skipping cooking.
- Marshmallows – mini marshmallows are best so they help create texture, but don’t look goofy!
- Pecans – or other nuts. Choose what you’d like and use 1/2 cup to go light on the nuts, or 1 cup for extra crunch.
- Cool Whip – thaw at room temperature so it’s easy to fold into the watergate salad.
