Pineapple mousse

I helped our new Couchsurfers make a pineapple dessert. The jelly in it went a bit wrong because it set before we were ready, but I discovered that a little stirring and heating was all that was necessary to bring it back to it's liquid form. We mixed the liquid jelly with some egg and pineapple and a few other ingredients. After that we put it into the fridge to set and the Couchsurfers went out to spend some time in central London. When they got back, we had the dessert. It was very sweet because we'd added condensed milk. I had three bowls of it. (the dessert, not the condensed milk). I thought I was being greedy but I looked around and saw that everyone else was also having a lot and that made me feel better.
