Pierre Koffman's Pistachio Souffle [Thermomix]

Pistachio soufflé with hibiscus flower ice-cream

We all know I love a soufflé, but now I have a thermomix I'm going through my recipes seeing how I can adapt them accordingly.  This Pierre Koffman soufflé was an absolute doodle in the thermo, the creme patisserie is now so simple to do, that soufflés are now a very real option for every day eating (though perhaps not to be recommended!).  It also means that it's a very simple and viable option for a dinner party - the creme patisserie has to be made in advance anyway, but whilst your thermo gets on with that, you can be prepping the rest of your meal!  Watch this space, soufflés are going to be flooding out of my kitchen...
