Mum's broken her arm and George and Flora go and ask Grandpa to help with making jam tarts. While they are there, he asks them to drop some eggs off at his neighbours, and gradually they realize that no one in the street knows each other and want to help. So they organise an amazing street party with lots of delicious home-cooked meals to eat. Packed full of recipes and tips for organising your own street party, George and Flora's Big Party is all about cooking and community: sharing recipes, making friends, helping to build a community in your neighbourhood.
