This 4-Probe Thermometer Is a Must-Have for Serious Home Cooks

My mom texted a few months back to signal enthusiasm for a new baked potato recipe. It was an America’s Test Kitchen recipe by Lan Lam where, at the end, the spuds’ internal temperature is checked with a thermometer. Mom’s already a baked-potato pro, so as peculiar as the technique sounded, I was curious to see what caught her attention.

At around the same time, I began reviewing a new remote-probe thermometer and, like the great scholar who thought to combine peanut butter and chocolate, I looked at the thermometer and that text from Mom and realized it was time to bake some potatoes.

Lam’s spuds get a quick bath in a salty brine, cook in a hot oven until their internal temperature hits 205 degrees Fahrenheit, come out for a quick coat of oil, and go back in for 10 minutes to crisp the exterior before you cut them open and slather ’em with butter. My gentle twist was to put a probe in both the largest and smallest potato and set the alarm in each to go off at 205 degrees. This kept me from needing to open and close the door and poke them with an instant-read thermometer every time I wanted a reading. I just set the temperature alarm and started listening for the beep about 45 minutes later. The result was so good, this will be how I make bakers from here on out.

The device I used was the Signals BBQ Alarm Thermometer With Wi-Fi and Bluetooth Wireless Technology, a four-probe thermometer with a base station that does everything a good cook or pitmaster would want. It offers temperature readouts and alarms, and it has an app that allows you to follow along by providing some time-temperature graphs of what you’re cooking, a nice additional feature not available on the display built into the base. The app also makes setting the alarm temperature easier, and if you’re cooking several different things at once, allows you to type in labels that appear on the base and correspond with each probe, like “brisket” or “chicken.”

This is the style of thermometer with a probe at the end of a cable that snakes back to the base. The probe goes in the food when you start cooking and stays there until it’s done, and you can read temperature information on the base, in the app, or on a dedicated remote display. Having the option of multiple probes means one of them could be an “air probe,” which takes the temperature at the cooking surface in your barbecue or oven. Setting it so that an alarm goes off when it hits a designated temperature is nothing new, but one of my first impressions with the Signals was remembering how freeing just doing that is; let the thing cook and go about your business until the alarm goes off.

Comparing Signals to the Smoke and Smoke Gateway combo, which I own and love, and reviewed several years ago, this newer model neatens things up with one base instead of Smoke’s clunkier three-piece system. Signals has the capability to run four probes instead of Smoke’s two. Four is a lot unless you’re really, really into barbecue. With something some long-cook barbecue fans will appreciate, Signals ties in with its Billows fan controller, meaning if the temperature dips, the fan spins to get the fuel burning faster. I was testing in Seattle’s wet, cold midwinter, and I have a gas grill, so I moved testing inside, where having four probes running into my oven was twice as many as I could ever imagine needing.

One of my first dinners with it demonstrated the basic pleasure of cooking with always-on probes. My sister came over with a nice salad, and I made the sweet potato and peanut salad from Vishwesh Bhatt’s cookbook, I Am From Here. I also made his pork tenderloin with tandoori spices, and since the loins were slightly different sizes, I put a probe in each, with the temperature alarms set, and tucked them in the oven, freeing me up to set the table and shoot the breeze. Not needing to interrupt the conversation every few minutes to poke the spuds with an instant-read thermometer gave us the fleeting feeling in our busy lives that we were real adults.
