Well said Chip and also the rest. Everyone is correct in a certain way.
I bought a IR thermometer a few years ago just to make my approach a bit scientific after decades of feeling the brew. There are some shocking reading esp. the great temperature difference between the water at top and bottom of the kettle. The difference can be 20 degrees. That makes me more conscious when I pour hot water from kettle. Without that findings, the feel can never be corrected.
If u intend to check the temperature, buy a good IR thermometer. Immersion or mercury thermometer is too slow to re-act.
Notwithstanding, now I am back to 'feel' mode.

So, off topic albeit, does IR detect surface temp or can it be directed to the depths of a vessel.
And yes, some thermometers are woefully slow. Some are really pretty fast. I literally bought a bunch and tried them out. But I am a bit of an instrumentation junkie which I fight to keep in check.

:
IR detect only surface temperature. I shot the ray on the top, mid and bottom of various kettles (silver, cast iron,volcanic clay etc etc) and the result is really interesting and the temperature difference can be drastic. The fun about IR thermometer is that we can entertain ourselves zapping all over the place when we are bored with the tea ceremony sometimes.

Yes, I posted about the temperature disparity within a kettle/pot not that long ago. TeaScience rox.

If you want a thermometer yanlokinh in e-bay sell a thermometres of °c and °F. Shippiest, but if you want to calculate the water temperature do it with your finger of your hand or the bubbles inside the saucepan.
I prefer the Bubbles.

So what are people's favorite fast-reading thermometers?
