Tramezzino al Mascarpone

A bartender at a Milan bar takes a tub of fresh mascarpone out of the under-counter fridge twenty minutes before opening, scoops a heavy spoonful into a small ceramic bowl, works it with a fork until it lifts in soft glossy peaks rather than tearing, and folds a knife-tip of cracked black pepper through it. Smoked salmon comes off the slicing board in translucent sheets. A loaf of pane in cassetta is unwrapped and the first two slices set aside; the next two, the inner ones with the loaf's softest crumb, are spread to both inner faces with the cracked-pepper mascarpone, and the salmon is laid in flat between them in two folded layers. The crusts are sliced off all four sides at the end in one clean sweep. The whole sandwich is cut diagonally, two triangles to the case.

Mascarpone is barely a cheese in the way the rest of the cheese case is. It is the Lombard whole-cream product made by acidifying double cream with tartaric acid or lemon over gentle heat and draining the curd in muslin overnight; the result reads closer to a heavy crème fraîche than to any rennet-set wedge: lactic, faintly sweet, almost saltless, with the cream's full fat still in it. Spread thick onto a soft white slice, it lands first as texture rather than as flavour, a smooth dense film, a slow mouth-coating richness, the salt threshold so low that the cream alone barely registers. The single partner in the build, salmon or pepper or honey, is what tells the bite what register to be in.

Three things go wrong with this filling and each is a temperature or a balance problem. Mascarpone spread fridge-cold tears the crumb of the bread along the spread line; the film breaks, the dome flattens, and the triangle cracks open at the cut. Mascarpone left at warm room temperature too long releases its cream and weeps a clear yellow oil into the loaf; by the time the triangle reaches the case, the bottom of the lower slice is greased through and dark. A partner chosen with no salt or no acid lets the bland cream stay bland; salmon brings cured salt, pepper brings a sharp burn, anchovy brings hard salt, honey brings sugar against the dairy. Without one of these the dome reads as an empty pillow of fat, which is the chief tell of a careless build.

Pick the triangle off the case with two fingers and the give is unusual. The bread does not crackle. The cream does not run. The whole object is uniformly soft and slightly cool, faintly heavy in the hand for its size. The first bite gives the white crumb without resistance, then a thick mouth-filling dairy slick that takes a full second to clear, with the smoked salmon arriving inside it as a saline thread and the pepper landing a beat later in a small dry burn at the back of the tongue. There is no crunch in the build. The aroma is faint and milky, the way a fresh cream label smells. A glass of cold spumante held in the other hand sharpens the cream against its sugar within a sip.

The Lombard-cheese filling rotates around the same crustless triangle and the same domed bind. Salmon and cracked pepper is the savoury aperitivo reading. Walnuts toasted and chopped, with a drizzle of acacia honey through the cream, is the sweeter pastry-counter version sometimes set out in the morning beside the coffee. Anchovy fillets, laid in over the spread with a few capers, push the savoury reading harder and read closer to the Piedmontese vitello tonnato counter than to the bar case. Each is the same fresh-cream Lombard cheese given one decisive partner; together they form a small subset within the Turin and Veneto bar's triangular row.

The closely related triangles in the same bar case are filled around other cheeses and use the same crustless dome. A version with cow's-milk blue and toasted walnut is the tramezzino al gorgonzola e noci. A salmon-and-rocket triangle without the cream cheese, bound only by mayonnaise or soft butter, is the lighter al salmone e rucola. A spreadable stracchino filling reads similarly soft but tangier and is a different bar triangle again. The mascarpone-and-cocoa-and-coffee mixture used in tiramisu and in some pastry cases is a closer cultural cousin but is built into a layered dessert, not a sandwich, and belongs to a different counter entirely.

A Lombard Cream on a Turin Triangle

The cheese predates the sandwich by several centuries. Mascarpone is documented in Lombard kitchen records from the late sixteenth and seventeenth centuries as a winter cream product of the cows pasturing in the Lodi and Pavia lowlands south of Milan, originally made between October and March when the cream's fat content peaks, and traditionally drained for the table or for pastry use as a fresh same-week product. By the nineteenth century it appears in Pellegrino Artusi's seminal 1891 cookery manual as a Lombard speciality used in sweet preparations; the dessert crema mascarpone, with sugar and Marsala folded through it, is among its earliest written sweet uses recorded for an Italian home cook.

The tramezzino form on which this filling sits is much younger and originates outside Lombardy. The crustless white-bread triangle itself was introduced at the Mulassano café on the central Turin square of Piazza Castello in 1925, modelled on the British tea sandwich but adapted to the Italian aperitivo bar; the bartender Angela Demichelis Nebiolo is credited as its creator. The name tramezzino is conventionally attributed to Gabriele D'Annunzio as a substitute for the English borrowing, with the meaning of the in-between thing. The cheese-as-filling family that includes the mascarpone build develops at the Veneto bars of Venice, Padua, and Treviso across the mid- and later decades of the same century, next to the better-known tuna and prosciutto builds on the same bar.

At the Caffè Mulassano in Turin the original 1925 marble bar still serves the crustless triangle on which this filling sits. The Italian Ministry of Agriculture lists Lombard mascarpone among the region's Prodotti Agroalimentari Tradizionali, with a recorded production method dating to the late sixteenth century in the Lombardy lowland around Lodi.
