Watergate salad, named after the Watergate scandal, has two primary ingredients: pistachio pudding and whipped cream, which is then mixed with canned crushed pineapple, marshmallows, and chopped nuts. For a variation, TikTok user @bdylanhollis used walnut and mini marshmallows in his own Watergate salad version, and you can also substitute whipped cream with regular cream.
