This thread almost convinced me to order one.
Yeah, they're that good. Fast, accurate, dead simple and durable. How many things can you say that about? I use mine for all sorts of things I'd never have thought of. Making bread? I use it to check that the water temp's 110˚-118˚ for blooming my yeast. Using my French Press? I use it to make sure the water has come down to 200˚ to avoid scorching the coffee. Same with brewing tea.
I use it for checking the temp on Hollandaise sauce so I don't get it too hot and curdle the eggs. I use it to check cakes. No more "insert toothpick, and if it comes out clean..." I shoot for 208˚-210˚. Bread, I shoot for 197˚-200˚. Perfect Salmon? Pull it off the fire at 140˚. You'll never have dry crumbly salmon again. Is that fried chicken REALLY done in the middle? Never a problem anymore. Well done steak? Not in this house. With the Thermapen I get them perfectly mid rare every time.
Want your Stout at a perfect cellar temperature? Pour it and let it sit on the counter until it's 50˚.
Is your wife really freezing, or is she just whining for the sake of interrupting your favorite TV show? Offer to "temp her" with the Thermapen just to make sure. She'll sit there quietly for the rest of the evening.
