Scotch whisky is cheddar's best friend. The Rob Roy is a Manhattan made with Scotch, the whisky bolstered by Angostura bitters and sweet vermouth. The complex flavour of this combination meshes beautifully with this creamy, buttery and elegant cheddar. The texture and mild acidity of the cheese are tempered by the vermouth and complemented by the bitters.
But it's really about the whole rather than the parts. The savoury flavours and silky texture of this cocktail make fast friends with the same qualities in the cheese, really bringing the nutty and fruity qualities to the fore.
