Stilton and Walnut

A wedge of Blue Stilton is set on the board and a walnut half is cracked against the side of it. The cheese is crumbling under the knife, ivory pricked with dark blue-grey veins, sharp and saline; the walnut is dry, oily, papery-skinned, faintly bitter, and when it goes between the teeth at the same time as the cheese the salt and the tannin land in the same bite. That single double-mouthful is the sandwich's whole reason for being. A slice of walnut bread is buttered firm, the Stilton is crumbled into the butter in a thick rough layer, the toasted walnut pieces are tucked down into the crumbled cheese so each one keys in and stays put, and the second slice closes over it. The cheeseboard's oldest English pairing has been moved between two slices and made portable.

The cheese in question is specifically Blue Stilton, an English cow's-milk vein cheese made in three counties only. It is registered under European Union Protected Designation of Origin since 1996, a legal restriction that limits the name to cheese matured by a small number of licensed dairies in Leicestershire, Nottinghamshire, and Derbyshire from local pasteurised cow's milk. The name does it. Strong on the nose, salt-led on the tongue, with a sharp, almost peppery finish from the blue mould, Stilton is firmer and drier than a French Roquefort and crumbles in flat sheets rather than spreading like a paste. That dry crumbling texture is what the sandwich works around.

The walnut is the under-recognised half. Roughly two-thirds of a walnut's weight is oil, mostly polyunsaturated, and the kernel carries a thin papery skin where most of the bitterness lives. Toasted dry in a frying pan for ninety seconds, that papery skin loses its raw edge and turns warm and faintly sweet without giving up the tannin underneath. A nut is then roughly broken rather than chopped fine: the rough piece keeps a real audible crack between the teeth, where a fine chop turns to bitter dust and disappears. The crack is half the sandwich. Skip the toasting and the nut tastes papery and raw next to the cheese. Chop too fine and the bite is salty rubble with no texture; the nut needs to stay a discrete crunchy thing inside the saline crumble.

Bring one out of the fridge half an hour before lunch and the barnyard note of the cheese comes up off the bread immediately, with the warm oil of the walnut faint underneath it. The bite goes through soft buttered crumb to a brief give from the cheese, then a clean dry crack as the toasted nut breaks against the molar. The salt of the Stilton lands first, sharp and pricked through with the bitter green note of the blue veins; the walnut tannin arrives a fraction of a beat later and pulls down the brine without sweetening anything. The fat of the cheese and the oil of the nut bond on the tongue. There is no juice. The aftertaste is woody and salty and lingers past the swallow.

An English Christmas cheeseboard sets out the same pairing as a course at the table. A wheel of Stilton sits beside a bowl of unshelled walnuts, a small dish of dried figs or quince paste, and a decanter of vintage port; the eater pulls out a kernel, takes a sliver of cheese off the wheel, and follows the bite with a sip of port whose own residual sweetness echoes what the figs do at the other end of the plate. The sandwich is the same pairing condensed for lunch the next day, leaving out the port but keeping the cheese-and-nut spine intact. A pub bar at noon often pours a small glass of port alongside on request, rather than from a board listing.

The cluster the sandwich sits inside is the family of strong-blue answers. Stilton and pear opposes the salt with a soft sweet bleed; Stilton and grape opposes it with a cool wet acid burst; Stilton and quince paste opposes it with a deep concentrated sugar; this version answers it with a dry bitter crunch instead. The blue itself is not a variant. Swap the Stilton for French Roquefort and the answer is a sheep's-milk vein cheese with a different salt and a wetter paste, and the sandwich is from a different country with its own page; swap it for Italian Gorgonzola dolce and the cheese softens to a spread and the sandwich is again something else. Each is its own object.

The three counties and the name

Blue Stilton's name has been disconnected from its village for nearly three hundred years. The cheese is named for Stilton, the Cambridgeshire coaching village where it was sold to London-bound coach passengers at the Bell Inn in the early eighteenth century by the innkeeper Cooper Thornhill, who is recorded as buying his cheese from his sister-in-law Frances Pawlett in the dairy country to the north. Daniel Defoe describes Stilton-on-the-road as the famous cheese market in his A Tour Thro' the Whole Island of Great Britain, published in three volumes between 1724 and 1727. The village itself has not made the cheese since the mark moved to the dairy counties.

The dairy counties are now a closed list. Blue Stilton has been registered under the European Union's Protected Designation of Origin scheme since 1996, restricting the name to cheese produced and matured in Leicestershire, Nottinghamshire, and Derbyshire from local pasteurised cow's milk; the rule has been carried over into the United Kingdom's own Geographical Indication scheme since 2021. Only six licensed dairies are entitled to make Stilton under that registration: Colston Bassett Dairy and Cropwell Bishop Creamery in Nottinghamshire, Long Clawson Dairy and Websters in Leicestershire, Hartington Creamery in Derbyshire, and Tuxford and Tebbutt in Melton Mowbray.

The pairing of the cheese with the walnut is a cheeseboard convention the British shelf has been carrying for over a century. The Stilton-and-walnut combination is a fixed item on the English cheeseboard alongside port wine in Edwardian household and entertaining manuals from the 1900s onwards; the sandwich version is the lunchtime reading of that after-dinner course. Cropwell Bishop Creamery has been making Blue Stilton in the village of Cropwell Bishop, Nottinghamshire since 1847 and remains one of the six dairies licensed under the PDO.
