@HopeSeeker In America, lamb can be anywhere between 8 to 14 months of age. In Britain, they sell hogget which is between 13 months and 2 years of age. (I don't think I've ever even seen hogget for sale here.) #Mutton is supposed to between 2 to 3 years and is considered #slowfood. I think the only way I'd ever find mutton is if I sent an older sheep to the processor, which is something I've considered, but haven't decided on. If you see mutton as a grocery, let me know!
