Socialising is the Supersizers’ prerogative as they go Twenties and experience life as bright young things. The episode sees “It Girl” Sue Perkins with an authentic bob haircut and Giles Coren in full dandyish attire supping cocktails at The Ritz, dancing the Charleston at the Café de Paris and racing Bentleys at Brooklands.

Recreating the general strike of 1926, Giles works on the buses and Sue cooks sausages for volunteers in the park, with the help of this week’s chef, food writer Allegra McEvedy. The Supersizers also visit an Egyptian exhibition at the British Museum, complete with a gourmet Fortnum & Mason picnic, to celebrate Howard Carter’s historic discovery of Tutankhamun’s tomb in 1922.

Giles and Sue are joined by Celia Walden, Diana Quick, Lord Ponsonby and David Taylor for a spectacular last meal of the week. Allegra prepares a “red” and “white” meal, which marks the end of the roaring Twenties and heralds the impending Wall Street Crash.
