We do the game hens for Valentine’s but do the goose for Christmas. I only do it once a year and usually forget from year to year how to cook it. Julia Child is best for oven steaming goose (and her duck recipes are superb). I don’t know if you do wild game but one out of three wild geese is worth it. The farm geese have alot of fat (like the succulence of wild duck versus farm duck) but the favor is unparalleled.
I've never tried it but I watched Alton Brown do one on Good Eats last week.
May want to go to FoodTV.com and check it out.
I do recall his slow roasting it first to get rid of much of the fat before turning up the oven to crisp the skin.
My wife roasts our turkey in a bag, comes out wonderful.
