Why People Love Thermapen


This is one of the best purchases in my kitchen: thermapen is very fast to read temperature, it is very easy to clean and store. I used it to check flour, water and sourdough temperature when proofing. I was worried that poking the dough would make it collapse, nothing like that. This tool really helped me to achieve better results in the kitchen.

I have bought a second Thermapen as a gift because I am very impressed with how fast and easy it is to use. Takes the guesswork out of grilling in particular.

Wow.. why did I wait so long in purchasing? I purchased 2 pens one for myself and one for a Christmas gift. Extremely satisfied. My Christmas Turkey was cooked to perfection. Clear readings and easy to use
