Isn't "lamb" a young sheep? How can it be tough and old?

Sheep meat is mutton. Makes a lovely curry.

Not the animal, the meat. The meat has been butchered and then left out too long. For some meats, aging in this way improves the taste or texture - Not so much for lamb.

Thanks!

In the US, there is no distinction made between the age of sheep in the labeling of its meat. No matter how old the animal, it's lamb, not mutton.

Wow! That finally explains why I never found mutton in the US. I've been curious about that for over a decade.

we call kangaroo sausages kangabangers - havent heard of anyone mixing with pork though

Interesting, most sausages use pork fat to keep the meats from drying out. If you don't use pork fat what kind of fat do you add to the kangaroo meat to keep it moist in a sausage?

Also, haha I love the phrase "kangabangers". Sounds like an outback criminal gang. "The kangabangers shot and killed two today."
