On Christmas day we're eating with my parents who are massive foodies, my mum is a completely brilliant (trained) cook. They're doing the main course and we've been asked to do the starter and dessert. I'd be so grateful to hear suggestions for what we might make - it has to be very special and can be challenging but our oven thermostat is broken and only works at the very highest setting, and my mum is allergic to most shellfish except prawns and lobsters. So please all you lovelies, tell me of the most spectacular starters and desserts you've experienced (that I can get the recipes for!) and that don't need to be cooked in an oven other than at a very high temperature. Thank you!
