I was trying to make a dessert that I had in a restaurant one time, it was a chocolate bag with white chocolate mousse. I failed horribly with a mousse recipe I found on Zaar, so I grabbed some things that were sitting around in my fridge and came up with this instead!
This is a fairly easy, but elegant recipe that can be made ahead, though I wouldn't fill the cups until the day you are ready to serve, or the juice from your fruit will collect in the bottom of the cup.
You can use whatever fruit you want... I used blueberries, sliced strawberries, raspberries and mandarin oranges.
UPDATE: For an ever easier time, try using silicone muffin cups instead of paper. I just bought some on the dollar rack at Target, and they make it much easier! Plus they're reusable!
