Which Thermometer Should You Buy?

The two types

There are two kinds worth owning. An instant-read thermometer, which you poke into food for a fast, accurate spot check, and a leave-in probe, which stays in the meat and monitors it throughout a long cook, often with a second probe for the grate temperature. They do different jobs and serious cooks own both.

Instant-read

For steaks, chops, chicken and any quick cook, an instant-read is what you want: a fast, accurate reading in a second or two. The premium ones read in about one second to within a degree, which is genuinely useful when a steak is thirty seconds from overdone. Cheaper ones are slower but honest and still transform your cooking.

Leave-in probe

For long cooks, a leave-in probe that you can watch from indoors is what makes an overnight brisket survivable. The important probe is the one clipped at grate level, because the dome thermometers on kettles and drums can read many degrees away from where the food actually sits. Wireless probes remove the trailing cable, which matters for rotisserie and closed-lid cooking.

The honest advice

If you buy one, buy a decent instant-read; it improves every cook you do. You do not need to spend a fortune. A slower, cheaper thermometer that you actually use beats an expensive one you left in a drawer. The habit of checking temperature matters more than the brand.
