Guilty Pleasures: Semi-Ambrosial Salad

I called this semi-ambrosial not because it is not ambrosial, but because I omitted one of the four total ingredients: coconut. I just don't like those chewy, dried out little bits of coconut hanging around in what should be an ecstatically creamy, fruity experience. This salad always presented itself to me in American cookbooks - it just seemed the sort of thing ladies in the South might serve alongside a ham dinner as a faint, fleeting gesture towards fruits and vegetables. I buy sour cream only to make this salad, and stock up on the rest of the ingredients at the drug store. This also seems like an American sort of gesture towards cooking for a buffet. Let this salad sit in the fridge overnight before you serve it - that way the marshmallows soak up the fruit juice and sour cream and get squidgy and creamy.

Mix together the fruit and half the bag of mini marshmallows. Fold in the sour cream. Refrigerate overnight. Serve. Beautiful.
