I've never had it, seen it offered on a restaurant menu or served at anyone's home or for sale at the supermarket.
Just wondering what domestic goose tastes like and why it seems to be shunned, at least in the Northeast?
(I had wild goose, once, smoked, at a Christmas buffet. That's not what I'm talking about, though.)
Goose tastes like goose. I know that's not terribly helpful, but it's hard to describe the flavor of something that tastes like itself and not like something else. The best I can say is that it seems to me like dark meat chicken, duck and turkey mixed. What's that taste like? Well, it tastes like goose. LOL
There is no white meat on geese, and the taste is richer than chicken or turkey, and mildly "gamey" if it's wild, less so, of course, if farm-raised. So if you're having goose, when considering accompaniments, choose things that complement steak, lamb or duck. As for sauces, orange, plum and/or cherry cannot be beat.
Perhaps the most useful thing I can say is that the flavor isn't likely to offend you; it's different yet close enough to other things you've had that unless you're have a very limited palate, you'll have no trouble eating it. Overdone roasted goose will have a metallic taste, and you probably won't much care for it.
FWIW, if you're going to be eating wild goose at this time of year, eat it sauteed (ideally
sous-vide to medium rare and then finished with a quick saute [1]) rather than roasted. Come late winter, roasted is the way to go because they've fattened up for the trip north, so roasting doesn't tend to dry and overcook the meat. This time year, most wild geese are burning their fat stores to make the trip south. If the goose is farm-raised, it's likely to be fattened whenever it's harvested.
So now you know what to ask the waiter -- Is it wild or farm-raised? If wild, has it been roasted,
sous-vide, sauteed, all or some of those methods, or some other cooking method used? -- if you see goose on a menu. Frankly, were I to see "roasted wild goose" on a fall or early winter menu and didn't have absolute confidence in the chef -- both his/her cooking skill and his/her ability to transfer to and obtain from his/her staff that skill level with goose -- I'd either choose something else or choose a different restaurant at which to order wild goose. Some proteins aren't seasonal in any way, others are. Wild goose is one that is. (So is wild "anything else" that migrates or hibernates.)
Note:
- A proper vacuum sealed cook is the best way to sous-vide cook food; however, if one is willing to go endure/risk the trial-and-error approach, one can approximate sous-vide by pressing as much air as possible from a heavy-duty ziplock bag and gently boiling the package. It's critical to get damn near all the air out of the bag, however, because if you don't when the air heats, it may expand and break the seal, in which case one'll end up with boiled and overdry/overcooked food which'll land you in the same place had you roasted it and overcooked it.
