As a child, this was one of my all-time favourite winter desserts. It’s called a self-saucing citrus pudding and just what you need on a cold day. I can imagine the flavours as I am writing. The feather light batter on top has a sweet-sour sauce which forms underneath as it bakes and is quite a surprise element if you have never eaten this before. So, if you’re making this for the first time, don’t be alarmed when you dish up – this is how it’s supposed to be.
