A leave-in probe thermometer and timer from Escali. The stainless probe on a 40 inch braided steel cord stays in the meat through the whole cook, in the oven or on the grill, while the display sits outside.
Set your own target temperature or pick from built-in settings for beef, pork, chicken, turkey, veal, lamb, hamburger and fish, and it beeps when you get there. The touch screen is backlit and wipes clean, and there's a 99 minute count up and count down timer.
The magnetic back sticks to an oven door or grill hood, or use the kickstand on the counter. Reads -4 to 572°F. Batteries included.
Wireless, with a receiver you carry: Maverick XR-50. Quick checks: Maverick DT-05 Folding Probe Thermometer.
