I know that meat thermometers generally won't handle as high a temperature range as candy, but I'm only planning to make caramels and fudge (so soft ball and firm ball) and that's within the range of the meat thermometer that I already own.
Also, meat thermometers are often labelled "medium well" etc., rather than "soft ball". Since I have access to the temps required, that's not an issue.
I'm definitely a noob to candy, so is there some magical reason I can't use a meat thermometer for my candy? Is it a huge no-no? Does it contain leprechauns that will destroy my caramels?
