So anyway, I managed to do all that without making a mess or ruining anything. Yaay! The mousse filled seven custard cups. I chilled them for an hour. Had one just now, and it's yummy! It's a creamy frothy mixture that tastes like Key Limes.
Mom also got some more pie shells so I can make more real pies. But that'll wait a while. Right now, we have all this mousse to eat!
