Perhaps one of my favorite pieces of kitchen gear, the immersion circulator (and specifically, this Sous Vide Professional Immersion Circulator CHEF series model from PolyScience Culinary) allows for complete control over temperature … meaning that you’ll never overcook anything ever again. You’re welcome.

If you prefer something at a more affordable price point, I suggest the Creative Series. Honestly, they’re all wonderful so see for yourself.
