Carbonade Valdostana

Carbonade is an Alpine adaptation of the Flemish and northern-French carbonade (carbonnade flamande), in which beef is braised in beer; brought into Valle d'Aosta, the dish was rebuilt with local produce and the beer replaced by red wine. It began as a dish of thrift and preservation: before refrigeration the mountain beef was kept under salt, and this salt-cured meat — slow-cooked with onions and wine to last — is the traditional basis of the dish, though modern home recipes commonly use fresh beef. The name is generally explained by colour: cooked for hours in red wine, the meat darkens until it resembles coal (carbone). It is served, like much Valdostan food, with polenta, sometimes alongside mushrooms.

Dark, almost black chunks of beef that pull apart under a fork, soft and yielding after the long braise. The sauce is deep and winey, thickened to a gloss, sweetened and softened by the slow-melted onions, with a warm back-note of clove, juniper and nutmeg. A salt-cured version reads saltier and more savoury, the onions there to balance it. Spooned over hot polenta, the soft maize soaks up the dark sauce. A good carbonade is tender and rounded, the wine cooked-out and mellow; a rushed one tastes harshly of raw alcohol and stays tough.

The long, gentle braise does two things at once: it breaks the beef's tough connective collagen down into gelatin so the meat turns fork-tender, and it cooks the harsh alcohol out of the wine while its acidity helps tenderize and its tannins and colour stain the meat dark. Dusting the chunks in flour and browning them first builds Maillard flavour and gives the sauce body as the flour thickens it. The large mass of onions, sweated down slowly, releases sugar and, with the wine's acidity, balances the richness — historically the salt of the cured meat. Kept at a bare simmer rather than a boil, the fat stays emulsified and the meat does not toughen.
