There was a post recently in which goat meat was called mutton. This started me hunting for a word for "goat meat".
It took me several days, but I have finally found one. Not in French where I thought it would be, but in Mexican Spanish, apparently: "Cabrito".

"For more than twenty years, the central Texas town of Brady has staged the World Championship Barbeque Goat Cook-off on Labor Day weekend. Cabrito is a delicacy that has its ardent admirers--and many detractors. To those who have failed to see the merit in a crunchy yet tender piece of goat meat, the blame must be placed squarely on the way it’s been cooked and on the fact that the goat you got probably wasn’t a ten-to-eighteen-pound, suckling kid slaughtered at thirty to forty days of age. Older goat is often passed off as cabrito, but once they start browsing on grass, goats develop an unmistakable mutton flavor. "
