Where does Costco lobster come from?

Costco sources its lobster from North Atlantic waters—most commonly from Canada and Maine. They use cooked claw and knuckle meat in the mac and cheese, which has a softer, sweeter texture. If you want more firm texture at home, go for tail meat or steam your own fresh lobster.

Is mac n cheese British or American?

A little of both! Macaroni and cheese is believed to have originated in Italy, but Thomas Jefferson brought it back to the U.S. from Europe in the late 1700s. Over time, it evolved into the baked casserole we know and love today. While the British have their own versions, it’s the American-style baked mac—especially the Southern kind—that dominates in flavor and popularity.
