I'm having a birthday party for DS next week and I usually make something for the grown-ups to eat too - scones or cake or something. One mum is gluten/dairy/nut free - she never expects anything to eat and always brings her own snacks to places but I'd love to make her something she can have. I've looked up some recipes but they all involved specialised ingredients, which I'd rather not spend lots on just for the sake of one recipe. Any tried and tested ideas?
