Why do geese need so much fat?

As part of Christmas dinner this year I cooked a tasty goose. I was astounded at the amount of fat that poured off it during cooking. Why do geese need so much fat?

Can I ask where your Goose came from? Was this a 'farmed' Goose bred and intensively farmed throughout it's short life specifically to end up on your dinner table? If so, I suspect that the amount of 'natural' fat in the flesh differs substantially from the fat that came out of your bird. Intensive farming, particularly of 'seasonal' birds CAN (not always) involve forcefeeding the bird foods that are designed to increase the mass of the bird as much as possible. I imagine that this would therefore result in a bird that is the equivalent of an Obese human - overfed and under exercised where the flesh of the animal is not well-used and developed muscle but fatty and water-laden.I imagine that there may also be factors involved such as the migratory and Summer/Winter environments of the birds in the wild that may favour greater fat deposits, but my personal suggestion would be that an extreme amount of fat would be detrimental to the flight of your bird if it existed in the wild and is more likely due to the farming methods used and lack of exercise/flight.

In my personal experience of preparing, cooking and eating wild goose, there is very little fat on these birds.To roast a wild goose correctly it is recommended that the breast and legs be covered by a layer of streaky bacon for example and slow cooked. This helps retain moisture in the meat keeping it moist and tender.The flavour of a wild bird is also that bit stronger than farmed goose.Under the African Eurasian Waterbird agreement, wildfowl such as wild duck and goose cannot be sold on. Therefore they are not easy to come by. I would recommend you make acquaintance with those who are involved with shooting, in particular, widfowling and make your next christmas goose a wild bird.The difference will be very obvious.

Domestic geese have been bred to put on weight, but the wild goose needs a good store of fat. One, they are migratory birds (climate obliging) and flight is energy intensive. Two, they need stores of fat to spend long periods on their nests--a good example of a bird which spends weeks on their egg without relief from their partner is the penguin, nature's chubby-whubby. Third, fat serves as insulation, which, along with waterproofing, is important to water birds, which constantly preen to oil their feathers. In short, geese are very athletic birds which can really pack the food in to support active lifestyles. All the more reason for getting fat when prevented from flying, swimming and fighting as much as they would in the wild.

I don't know why the geese have this but we drain it off and keep it in the refrigerator. It is excellent for cooking. You can use it for frying, basting and so on. With a sprig of rosemary added it makes excellent roast potatoes. You can buy goose fat in the shops and it's expensive. We find the Christmas goose's dripping keeps for the better part of a year!
