Bacalhau à Zé do PipoSalt cod with mayonnaise mash
Zé do Pipo was the nickname of a Porto tavern keeper in the 1960s whose cod won a national cooking competition, and the dish became a celebration plate in northern restaurants ever since. Thick cod loins sit on a bed of slow-cooked onions, are covered in mayonnaise and ringed with piped mashed potato, then baked until the top turns golden and blistered. Use a good shop-bought mayonnaise made with pasteurised egg; homemade mayonnaise with raw yolks is not for pregnant women, young children or anyone with a weakened immune system. A common mistake is a runny purée; the potato must be stiff enough to pipe, or it slumps under the mayonnaise. Chef's tip: pipe the mash while it is still warm, as cold mash cracks.
