A Cornish hen, also called a Cornish game hen, is a small, young chicken, typically 4 to 6 weeks old and under 2 pounds, bred to be tender with a proportionally higher ratio of meat to bone than a standard broiler. Despite the name, the product was developed in Connecticut in 1950 by crossing a Cornish cock with a White Plymouth Rock hen; 'Cornish' refers to the Cornish chicken breed used in that cross, which itself originated in England in the early 1800s.
Its small size makes it a natural single-serving portion, usually roasted or grilled whole and served for special occasions. Its flavor is similar to chicken but slightly more pronounced, and it pairs well with herbs like rosemary and thyme, garlic, lemon, and pan sauces.
