I've never made Iles Flottante before, but I love soft meringue and have 6 egg whites waiting to be used up. Trouble is, I don't have the yolks--used them for a custard last week. Any thoughts on how to vary what the islands will be floating in so I can use up these whites? I'm not huge on caramel either, so I was thinking maybe a mocha-flavored sauce? But I'm open to any suggestions.
