After watching Alton Brown cook a roast using one of those new thermometers (the kind that stay in the roast with the oven door closed and you set its alarm to sound when it's reached the right temp.) cooking by temp. instead of cooking by time.....I bought one for my Mother. Do any of you computor wiz's know where I could find more infomation on how to use these thermometers? I'd like to give her some clear instructions, with possible examples.... I looked back at Alton Browns show and it really didn't give me all the info. I was hoping to show her. I really think this is a brilliant concept....are any of you using one?
