meringue

The etymology of meringue is genuinely uncertain, and the uncertainty is itself revealing about how culinary vocabulary travels. The French word meringue appears in written sources from the early eighteenth century — the earliest known recipe is in François Menon's La Nouvelle Maison Rustique of 1692, though the preparation may be older. The word's origin has been disputed among three main candidates. The first and most commonly cited is the town of Mehrinyghen (now Meiringen) in the Bernese Oberland of Switzerland, where according to a persistent legend a Swiss pastry chef named Gasparini invented the preparation in 1720. This folk etymology is doubted by most serious etymologists — the documented history of meringue predates this date, and the derivation from a place name requires a phonetic evolution that is not straightforwardly explained. The Grimm brothers, in their German dictionary, noted the Swiss place-name theory without endorsing it.

The second etymology connects meringue to the Polish word marzynka or the German Märingel, names for similar confections of beaten egg white and sugar in Central European cooking. The Germans did have a tradition of gebackener Eischnee (baked snow) or Spanische Windtorte (Spanish wind cake) — airy egg-white confections — that parallels and may predate the French meringue. The word's relationship to these Central European preparations has led some food historians to suggest that meringue traveled west with the wave of Central European culinary influence that accompanied the Baroque courts of the seventeenth century. A third, minority etymology derives meringue from the Latin merendare (to eat a light afternoon snack), via the Old French merendre, suggesting that meringue was originally the name for a light between-meal sweet. None of these derivations has sufficient documentary support to be conclusive.

Whatever the word's origin, the preparation itself is a case study in the physics of sugar and protein. Egg whites, which are roughly ninety percent water and ten percent protein, can be whipped into a stable foam because the albumin proteins in the white denature when agitated — they unfold from their globular forms and entangle with each other around the air bubbles whipped into the liquid. The addition of sugar stabilizes this foam by increasing the viscosity of the liquid film around each bubble and by binding water molecules, preventing the foam from weeping. When baked at low temperature, the water evaporates slowly, the protein network sets permanently, and the sugar caramelizes slightly on the surface. The result is the paradox of meringue: a structure that is both rigid and fragile, that holds its shape until the moment it shatters. The three main types — French meringue (uncooked, beaten with cold sugar), Italian meringue (stabilized with hot sugar syrup), and Swiss meringue (beaten over heat) — reflect three different ways of managing the protein-sugar chemistry.

Meringue arrived in English in the early eighteenth century and quickly established itself as a marker of culinary sophistication. The great meringue confections of English and French pastry culture — pavlova (a meringue base with whipped cream and fruit, a preparation whose invention is contested between Australia and New Zealand), île flottante (floating island, a poached meringue on crème anglaise), dacquoise (a nut-flavored meringue layer cake), and the lemon meringue pie of Anglo-American domestic cooking — all deploy the same fundamental preparation at different scales and in different applications. The word meringue carries in English both the specific culinary sense and a loose metaphorical sense of something that is all sweetness and airiness with no structural substance — 'meringue politics,' 'meringue celebrity,' the thing that looks substantial but is mostly trapped air.
