Tiramisu

Tiramisu is a Fantasy/Concept gourmand accord — a perfumery reconstruction of the Italian layered dessert (mascarpone cream, espresso-soaked savoiardi ladyfingers, cocoa dust, often with a splash of Marsala or coffee liqueur). It is not a perfumery raw material; the accord is built molecule by molecule from synthetic blocks evoking the four principal flavour layers.

Reconstruction

The coffee top of the accord turns on 2-furfurylthiol (CAS 98-02-2) [A], the defining roasted-coffee thiol — an extraordinarily powerful compound used at parts-per-billion. Around it sit 2,5-dimethylpyrazine and other roasted Maillard pyrazines for depth. The mascarpone-cream body uses δ-decalactone and γ-nonalactone for fatty milky character, with acetoin (CAS 513-86-0) for buttery lift. The cocoa-bitter signature comes from isobutyraldehyde, theobromine-adjacent pyrazines, and a trace of vanillin. Ethyl maltol and vanillin round the savoiardi-warmth.

History of the dessert

Tiramisu is genuinely Italian but comparatively recent. Documented to Le Beccherie restaurant in Treviso, Veneto, around 1969 — invented by chef Roberto Linguanotto and proprietress Alba Campeol. The name tira-mi-sù (Venetian for 'pick me up') refers to the caffeine-and-sugar lift. The recipe spread through Italian restaurants worldwide during the 1980s and became one of the country's most exported desserts.
