Keens Steakhouse (formerly known as Keens Chophouse), one of the few traditional restaurants that serves what they refer to as a mutton chop, purchases older lambs aged 10 months to one year, and usually a bit older, says Jenkins. While not considered mutton by U.K. standards, the taste of a 10-month-old lamb is still very different than that of a 6- to 8-month-old spring lamb.
The quest to score actual mutton is tricky. The meat is popular among Navajo and Pueblo peoples, is often used in Pakistani, South African and Indian curry dishes, and can be found at small suppliers like Apple Creek Farm in Maine, which sells rosemary mutton sausage.
A hard find
Outside of farms and niche markets, mutton still poses unique challenges. To create a tender meat, it needs to be hung in a cold room that allows its enzymes to break down. When supermarkets took over meat production, they weren't eager to hang meat because it's money in the fridge, Kennard says.
McGuire, who owns a modest farm, says she pays more than $150 per sheep just to have it processed, and that a severe lack of infrastructure to support sheep farming is to blame for why the meat is so expensive to maintain and ship. A local brewery buys her mutton to make a sausage dish affectionately called Baahwurst, but a local upscale chef, also a buyer, labels his "lamb"on menus. Despite the popularity of the dish, McGuire says customers can't get past the label "mutton."
Millennials and more experimental diners on both coasts might be open to eating mutton, McGuire says, but when one high-end restaurant in New York City purchased her USDA-inspected mutton, it "cost a bloody fortune to ship — three times the cost of other meat." Mutton must be shipped overnight and packed in dry ice, and the additional costs, McGuire explains, include a Hazmat charge on top of an overnight shipping charge.
A mutton revival on the horizon?
Still, McGuire, Kennard and other champions for mutton say the meat has a lot to offer and that rebranding, re-education and investment in small processing plants are needed to create new buzz around the industry. In the U.K., where the Mutton Renaissance Campaign was founded by Prince Charles, those efforts include a push to categorize mutton by location and breed. In the U.S., farmers like McGuire are also eager to differentiate between breeds and diet (grass-fed mutton is tastier, according to experts), while celebrity butchers like Adam Danforth are using social media to impart knowledge on the delicious benefits of dry-aging sheep.
According to Danforth, Americans have been informed, told, reminded and marketed by a commercial industry that tenderness is the ultimate characteristic of good meat, and he calls it a ploy that plays into their model — because tenderness comes from the opposite conditions that flavor does. Mutton is neither tough nor gamey, he argues, and is a superior eating experience to lamb. "In fact, lamb these days is more and more being developed to taste less like the species of sheep and more like beef to better appeal to the mainstream," Danforth says.
Mutton's best days may actually be ahead of us.
"Good mutton is like the best steak you've ever had," McGuire says. "The biggest problem is getting people to try it."
