Marks & Spencer, Lustau Pedro Ximénez, Jerez, Spain

Made by Sherry luminaries Lustau, a little of this nectar goes a long way – it has a whopping 410g/L of residual sugar (Port is generally around 100g/L-120g/L). It's unctuously decadent and would make a great pairing to pecan pie or sticky toffee pudding, thanks to its flavours of molasses, prunes, raisins and figs.
