At Roux Parliament Square, the pre-dessert is a panna cotta, topped with a jelly, and then a refreshing granita. On the day I went we had a coconut/passion fruit/lime, but I notice from trawling reviews that they also do apple/apple/cucumber (yum!), pineapple/coconut/kaffir lime, strawberry/strawberry/meringue. So it's a very successful formula, onto which you can put your own twist. If you're going to do this regularly, you'll need some better glasses than mine, I'm on the lookout for something far prettier,
a little like this...
