Laurence Llewelyn-Bowen

Celebrated fashion designer and presenter Lawrence Llewellyn-Bowen drops by for lunch and turns Prue's kitchen into an art gallery with a display of his latest collection of paintings. But what will someone who confesses to never cooking himself arrive at the table with? Meanwhile, John heads out into the grounds to plant a tree he hopes will stand for generations. Always one to mix things up in the kitchen, Prue decides to make a chocolate mousse cake – with the addition of pink peppercorns. Her handy hacks this week include turning carrot tops into a delicious pesto, and showing how you can add a dashing splash of colour to an otherwise ordinary looking meringue. We meet a Cotswold-based food producer who's taking on – and beating - the Europeans at charcuterie. Prue and John want to use some of his salami and sausage in their dinner - but how well will it work when you're producing your own pizza, and doing the whole thing from scratch?
