Bought a thermapen so I could cook steak for for me and my partner on valentine's day. Was always nervous about cooking meat because I don't want to overcook it and ruin an expensive treat. Thanks to the thermapen I was able to get really good results and an excellent steak in the end
There’s no better instant read thermometer on the market. This is my 2nd Thermapen, I wanted a 2nd one for convenience and the fact I returned to purchase a 2nd says it all.
I recently purchased this thermometer for making yogurt, and it has been a game-changer. It gives quick and accurate readings, which is essential for getting the perfect consistency. The design is user-friendly, and it’s easy to clean after use. It has definitely improved my yogurt-making process, and I would highly recommend it to anyone who needs a reliable kitchen thermometer. :)
It might just be a thermometer but it does its job so well. Open it, measure the temperature, close it and you're done. It's very responsive and gives plenty of confidence that your food is cooked or at the temperature you want.
Having this in the limited edition cherry colour means no one else can claim my probe without me knowing it’s mine! Upgraded from the standard thermopen to the ONE and the backlit rotating screen is perfect for reading inside of an oven! Proper quality product!
