Stracotto d'asino

In the lower Po plain, donkeys were the universal draft and farm animal; slaughter at the end of a working life provided cheap, tough meat that demanded hours of cooking. By the 19th century, stracotto d'asino was already the standard winter Sunday dish at Mantuan country osterie, kept simmering all day so innkeepers could serve it at any moment — the long cooking time an operational advantage, not a burden. The village of Belforte, in the Mantuan countryside, is traditionally cited as the heartland of this preparation, though the broader Bassa Mantovana and lower Padana plain share the tradition equally. Today donkey is difficult to source and beef chuck is the accepted substitute, while the name and slow-braise technique survive unchanged.

Yielding and wine-dark, the meat offers almost no resistance — a trembling softness that dissolves into the glossy, iron-rich Lambrusco gravy; the polenta beneath absorbs every drop of the dark sauce.

Donkey meat is lean and its muscle sheaths are dense with type-I collagen. An 8-10-hour braise at 85-95 °C gradually hydrolyzes collagen into gelatin, which dissolves into the braising liquid and coats each fibre, producing the silky, yielding texture. Lambrusco contributes polyphenols that partially bind myoglobin (reducing gaminess) and tartaric and malic acids that disrupt tough protein cross-links over the long cook. The initial Maillard sear at 150-160 °C surface temperature generates pyrazines and furans that persist through the eight-plus-hour braise, enriching the sauce continuously.
