Dammit, after a second failed fudge batch I finally thought to do a calibration test on my fancy new digital candy thermometer. Apparently water boils at 102.2 C! I did not know that!

Bah. At least a second test came up with the same result, so I can just add a constant. But I'm really mad at myself for not checking my instrumentation earlier, particularly when it's such a simple test.

Did you use distilled water? Dissolved solids can make a significant difference.

It boils at about 94C here... and in Leadville I think it's 88C.

We were discussing altitude vs boiling point yesterday. When I went and looked it up, and got the 500ft = 1° rule, I was amused, as it means water boils at nerdvana at 211f (99.4C).

Now I'll need to check my various thermometers.
