A retro classic made healthier: cherry pistachio fluff recipe

This cherry pistachio fluff is one of those totally retro classic picnic dishes that a beehived, '60s-era housewife might bring to a summer barbecue in pedal-pushers. People still make this creamy dish because it's rad as hell, super customizable, and easy as hell. I've taken the original concept, added a little pistachio twist, and lightened up the ingredients.
