If your goose came frozen, you will want to defrost it in the refrigerator for two days.
Start removing the fat from the tail area of the bird. You will have a lot of fat, but don't throw it away!
Remove the giblets. Don't throw them away, use them for another purpose.
Wipe the bird with a paper towel, then take a fork and prick all the skin well. This is important so the fat comes out while roasting.
Put the celery, onion, and apple in the cavity. If you have other vegetables or fruit bits laying about, put them in as well.
Fill the bottom of your roaster with about an inch of water. Put the rack in. Try to raise the rack above that water, two clean cat food cans do a good job.
Put the goose on the rack, breast side up, and roast your goose at 350°F / 176°C for about 2 1/2 to 3 hours. It should be 165°F / 73.89°C on an instant-read thermometer.
Let the goose rest for at least 5 minutes before carving.
Sour Cherry Sauce
Mis en place
In a small pan, melt the butter and add the cornstarch. Whisk the cornstarch thoroughly so there are no lumps.
Add the preserve, whiskey (if using), and mustard, and continue stirring constantly until the sauce thickens slightly.
Put in a nice serving dish and serve warm with goose or other gamey fowl.
Your goose is cooked!
Notes
Stuffing the cavity with bread stuffing is not recommended because geese are very fatty, stuffing adds time to roasting, and there is a possibility of cross-contamination.
