Matilda and the Ramsay Bunch are back home in London and they're throwing a party for some of their friends.With a party to organise the gang get to work. Matilda's brother Jack and sisters Megan and Holly take shopping to another level, as they speed along the river Thames on a high-performance rib to pick up supplies.Matilda's in charge of the party food: build-your-own spicy sausage pitta bread sandwiches with zingy yoghurt sauce and popcorn cakes.The popcorn cakes idea came from Scarlet, a Matilda and the Ramsay Bunch viewer who emailed it to Matilda's Food Blog. Great food, friends and fun, and the party finishes with a bang when everyone plays an explosive game with a watermelon – parties don't get much better!
