Got a new long clip on candy/oil thermometer from "Surly Table"
recently. The directions for calibrating it say:

"Immerse thermometer in sheath in at least 2 inches of boiling
water...Adjust hex nut beneath dial with calibration tool on sheath to
212 degrees F."

Sheldon probably knows the answer here, but i'm tossing it out for
general consumption: What does leaving it in the plastic sheath do here?
And I'm not sure what part of the sheath is considered the "calibration
tool" although the hex nut under the dial is apparent.

Input welcome :)

Should do. Otherwise it will be set to the wrong value.

Because you're calibrating it for *your* kitchen? Does it warn
against calibrating in Death Valley, then using it in your Rocky
Mountain friend's kitchen?

Just wondering.

Your best bet is to find out the boiling point of water at your attitude
and calibrate it to that temperature. The sheath might be used to
prevent water from leaking into the probe end but I wouldn't calibrate
it with that on. I'd pretty much ignore the instructions.

the calibration if it's within +/- 3º... cooking doesn't require
laboratory accuracy... and changes in barametric pressure affect
thermometer readings anyway. And the weather does affect cooking
results. Anyone concerned with super accuracy will be calibrating
that thermometer every day.

Now I'm wondering if that trick works for other thermometers with a

Should be distilled or deionized water, of course.
Tap water boils at a slightly higher temperature.

As Sqwertz pointed out, 212F is 212F at any altitude.
It's the boiling point of water that changes with
altitude.

you like just remember to add or subract when using that thermometer..
that's true with all cooking for people who know how to cook.. good
cooks go by results, not anticipatory BS.

If the indication on the thermometer says "boiling",
then you'd be right. On the other hand, if it says "212",
you're wrong.

Obviously you don't/can't cook. No thermometer is marked 'boiling',
simply because there are many circumstances that play a part on at
what temperature water boils. However to calibrate the particular
thermometer in question by the instructions supplied the best one can
do is to calibrate it at the location where it will be used... if one
cares to make changes with interpolation by some chart that's a
choice, but totally unnecessary... there is no reason to have a
number, any mark will do at the point at which water boils at that
location. I wouldn't use that calibration method for a candy/frying
thermometer, sugar/oil behave differently from water. I'd consider
the mark at which water boils a point at which to interpolate
temperature for other substances. For numerical accuracy one would
need a standard for each temperature range desired. But cooking does
not require laboratory accuracy, a good cook uses all their senses,
most professional cooks never use a thermometer, they can tell the
condition of a food from visual, odor, sound, feel, and of course
taste.

My home heating thermostat is located in a center hallway, but I have
a thermometer in every room, simply because none of the room
temperatures are at the temperature shown on the thermostat because
each room is different in how it receives heat and maintains
temperature, all buildings are the same. And since my house has two
zones/two thermostats that complicates things further. I don't use
the numbers on the thermostat except as a rough guide, I made a mark
that best maintains the temperature I want in the rooms most important
to have a certain comfort level. Cooking the same... just because a
recipe says to roast something at 325º that doesn't mean that for ones
oven, the shape of the roast, and several other factors that's the
ideal temperature. I rarely cook a roast relying on a meat
thermometer, I get better results with oven temperature time and using
all my other senses. With cooking anything there are too many factors
involved to rely soley on temperature.

You dont want the boiling temp of water because you wont be making
water. The sheath might possibly be the insulator that allows the so
called boiling point to be higher for all the liquids that are not
water.

I think they copied the text from a non-candy thermometer, as the regular

the "leaving it in the sheath" language is a bit baffling, but they probably
meant the metal pot clip.

Which means you're wrong, of course.

If Shelley really is flustered, I think it's because he's self-flustering.

You're talking about 212 for pure water versus 212.003 for tap water. No
home cook has a thermometer that measures with that degree of precision.

I used to have one of those thermometers. They are beautiful but mine
broke. The method of calibrating these probe thermometers are similar.

The oven thermometers that I have are adjusted by turning the flat screw
in the back of the unit. Unfortunately, there's no way to calibrate
these things unless you have a calibration source.

Buy a Thermapen. Measure any liquid which is at a stable temp. Immerse your new thermo. Calbrate to match the Thermapen. ;-)

Going by boiling water has one inherent problem... whatever the boiling point is at your altitude is the max temp the water can reach. If you are at sea level, at normal atmospheric pressure, you cannot heat water over 212F. At other altitudes, it's different. So what you need to know if you want to be really precise is what the boiling point of water is at the altitude where you live. Or, one can just do as I suggested upthread and buy a Thermapen and calibrate by matching the candy thermo to the Thermapen reading. Actually that was intended as a semi-smartass response but there is a reason to do it that way.

The thermo is intended to be used for candy or oil which as you correctly pointed out, does not have the same idiosyncracies as water based on altitude. Since by definition the boiling point where the average person lives is probably not precisely 212F, there is no way to calibrate a candy thermo using water and be truly accurate unless you know the exact boil temp of water where you live. And calibrating to oil can be done at a higher temp much closer to the actual candy or frying being done. This reduces the amount of potential error.

Don't all confectioners live at sea level? Using a thermometer for
cooking is like using a slide rule for math, one must accept that
there will be a degree of interpolation... all cooking involves
interpolation anyway. Professional cooks don't use thermometers, they
rely soley on experience and all their senses.

I'll be glad to wait while you test that theory and report back. You may want to go ahead and make an appointment with a GI doc now... those probes are pretty sharp.

I guess my main issue with boil testing is
