Here’s the kicker: most ham you buy today is already fully cooked. Seriously. A spiral-sliced, city-style ham from the supermarket has been brined, cured, and steam-heated before it even touches your oven. You’re technically just reheating it. But that doesn’t mean you can just slap it in the oven and call it a win. If you overheat that pre-cooked ham, you’ll turn a $50 centerpiece into a salty, dry hockey puck. The goal is not to “cook” it—it’s to warm it through to a safe, glorious serving temperature.
