It's interesting to note that the term pot roast actually refers to a method of cooking rather than a specific cut of meat. It involves slow-cooking the beef in liquid, usually on the stovetop or in the oven, to create a tender and flavorful dish. So, in theory, you could use a chuck roast to make a pot roast, but you could also use other cuts of beef.
On the other hand, a chuck roast is a specific cut of meat that's known for its rich flavor and tender texture. It's often used in stews and braises, where it can simmer away for hours and absorb all the delicious flavors. But if you were to cook a chuck roast using the pot roast method, would it still be a chuck roast, or would it become something entirely new?
One way to think about it is to compare it to a car - just because you use a Ford to drive to the beach doesn't mean the beach becomes a Ford beach. Similarly, just because you use a chuck roast to make a pot roast doesn't mean the two terms become interchangeable. But at the same time, who cares what you call it, as long as it tastes amazing?
