What the dish is
Cordero a la miel is slow-roasted lamb — shoulder or leg — cooked until it falls apart, in a sauce built from honey, white wine or sherry, garlic, onions, bay leaves, rosemary, oregano, and a touch of vinegar. The vinegar matters: it tempers the honey's sweetness so the result is complex rather than cloying. The sauce reduces to something silky and deep, somewhere between a jus and a glaze.
This is not a tapas bar dish. It's a sit-down main course, typically served with roasted potatoes and pearl onions. Expect to take your time with it.
