VIDEOS: THE SCIENCE OF CHRISTMAS

When it comes to cooking turkey, chefs and home cooks have plenty of strategies to keep the bird moist during the cooking process.

Turkeys are difficult to cook because they are so big and round that they can be considered spheres, which are an inefficient shape for cooking because it takes longer for heat to travel to the centre of the bird.

Often, by the time it is cooked through, the skin may be burnt and the outer layers of breast meat may have dried out.

Methods to keep a turkey moist include brining, or immersing a raw turkey in a salt solution for a period of time. This changes the structure of the protein in the muscles which, in turn, helps it retain moisture during roasting.

Changing its shape can also allow it to cook more evenly. Spatchcocking, a method that involves butterflying the bird by cutting out its spine and breaking its breastbone, is one way to turn the sphere into a flatter and more efficient shape for roasting.
