We usually keep a bottle of a very dry sherry (Fino) in the fridge. A nice tipple when carving the roast and making the gravy. Also a good accompaniment to tapas. Chorizo, prawns, Jamon pata negra etc.
Tio Pepe Fino is the classic choice (Jerez), But a Manzanilla like Gitana is equal, if not better. The small bottles of Tesco Finest are usually good.
A little less dry, and a bit more nutty and flavoursome, are Oloroso and Amontillado. These can be dry or sweet. The little finest bottles are usually at the dry end. Very good.
I wouldn’t bother with the well-known brands like Harveys and Croft. Tend to be designed for the traditional British palate.
We boycotted Tio Pepe for a while after doing the Gonzalez Byass bodega tour in Jerez. It turned an icon into a commodity. But then the Co-op was flogging it off at half price. What price principles, indeed.
