Well, let me see...
If it were me, I would brine the goose before baking it just like a turkey.
Take a very clean 5 gal bucket and add about 2 or 3 gallons of cold h2o. To the water add a half cup of salt and a 1/2 cup of sugar, a handful of whole peppercorns, a few bay leaves, and as many cloves of garlic ( smashed ) as you have available. You can also add any other herbs or spices you have and enjoy as well. Rosemary might be a nice addition.
Make sure the salt and sugar dissolve in the water and add the goose. Add a bunch of ice to the bucket and put it in your spare fridge for at least 24 hours. It helps to take a large jug or some other container you can fill with water and put on top of the bird as a weight to keep it under the water.
Don't have a spare fridge? Well, I have kept a turkey in the bucket, covered in ice with an electronic thermometer set to 35 degrees in a cool room in my house. The thermometer had an alarm so I could add more ice if the temp rose above 35 degrees. I have not had any issues with spoiling or sickness from the turkeys I have done this way so far.
The bird will absorb some moisture and flavors from the brine solution. Just let it drip dry on a oven rack over your sink for about 15 minutes before you bake or fry it as normal.
