Should I brine a goose? I've had really good luck with brining turkey &amp; chicken. I am making goose for this Christmas and have found mixed suggestions on whether to brine the goose. Does the fat content of an average goose lend towards not brining? Are their alternate techniques that would better bring out flavour in a roast goose (just do a straight roast, no brine)?
No. The fat content of goose, like most waterfowl, is very high. This makes it unsuitable for brining. Brining is intended to bring moisture to meats that tend to dry out, such as chicken and turkey.

See my answer to "What are the basics of brining meat?" for more details.
