So apparently in dessert terms a 'fool' is anything that involves folding fruit in with whipped cream. This recipe involves mango, heavy whipping cream and the secret ingredient of labneh, a mediterranean style yogurt (or in it's place you can use sour cream - Trader Joe's sells a version of labneh in a tub so it should be pretty easy to get if there is a Trader Joe's near you, or a fancy market.).
1/4 pint heavy whipping cream (1/2 a small container)
1 c labneh/sour cream
2 ripe mangos (is it mangoes?)
1 T sugar (plus more to taste)
lemon or lime, freshly squeezed
in a bowl, stir the labneh (or whatever you choose to use) to loosen it up a bit
in a separate bowl, whip the heavy cream until it is thick, but not so thick that it holds stiff peaks
fold the cream into the labneh
in a blender of food processor, puree the mango w/1 T of sugar and a few tablespoons of lemon or lime juice (to taste)
fold the mango into the dairy mixture, add more lemon/lime juice and/or sugar if you want, and you're done!
