Codornices en Escabeche

Codornices en escabeche belong to the Ebro country of Aragón and Navarra, where small game birds are browned whole, cooked gently with onion, carrot, garlic, bay, wine vinegar, and olive oil, then left to rest in that sharp, fragrant liquor. That rest makes it escabeche. This isn't roasted quail with a little vinegar tipped over at the end. The seasoning must pass through the meat, and only time will carry it there.

The point that decides the dish is the heat after the vinegar goes in. Keep the liquid at a bare simmer and stop cooking as soon as the quail is done. A hard boil dries those small breasts before the legs soften, while the vinegar loses its clean edge. Let the birds cool in the escabeche, refrigerate them submerged, and give them at least twelve hours. A full day is better. The oil, vinegar, game juices, and softened vegetables settle into one another while you do nothing at all, which is a useful sort of cooking.

Farmed quail, fresh or properly thawed from frozen, works very well far from Aragón. If quail simply isn't sold where you are, use bone-in chicken thighs and extend the gentle cooking time; what you have then is pollo en escabeche, a proper household dish in its own right, but not codornices.
