I love the classic English desert Eton Mess with raspberries instead of strawberries. And it could not be easier Gobo.
Meringues, whipped cream (you can sweeten it with a little icing sugar and vanilla to turn it into cream chantilly if your GF has a sweet tooth) and raspberries. You can even buy the meringues. All you do is crush the meringe roughly in your hands and fold into the whipped crean and raspberries. I blitz or crush a few raspberries to help it along, and it looks beautiful and marbled. Its not fancy but its nice.
In omnibus amor et iustum
