The good news is that most hams that Americans buy at the supermarket for Easter Sunday are known as city hams, which are precooked. They’re wet-cured hams that are technically safe to eat as-is, without even heating them up. All you have to do is:

But how do you know the ham has reached 145 degrees? Are you some sort of wizard?

All you need on hand is a meat thermometer. Our favorite is a digital instant-read thermometer, because it’s fast, sleek and relatively affordable. Your next option is a traditional instant-read thermometer, which is usually a little more affordable but takes longer to measure temperature than the digital version. The third type is a probe-style digital thermometer, which can be inserted into your ham with a wire leading out of the oven door to a digital display that monitors the temperature. It’s a little clunkier, but it gets the job done.

A few of our favorites are below. Order one now and you’ll be happy you have it on Easter! (And Thanksgiving, and literally every other time you cook meat.)
