Had a lovely chocolate mousse at a Greek restaurant in Toronto back in February, so I decided to try my hand at making my own. It's adapted from the middle layer of the triple chocolate mousse cake from America's Test Kitchen. I added espresso powder to give it a mocha flair.
And yes, it's very yummy. Should also freeze well in these canning jars, which is handy for when guests drop by. The canning funnel made it easier to scoop mousse into each jar w/o leaving a huge mess.
