What is it? It’s a thermometer for your meat. But it’s cleverer than your bog-standard mercury/glass tube combo. There’s an app that lets you monitor its progress, or you can connect it to Alexa then simply ask how long your food has left to cook.
Why you need it: Well, it’d be awful if you undercooked your meat. Best case scenario: everyone talks about you behind your back. Worst case scenario? Everyone talks about you behind your back, then dies.
