Here is another tip.
Thermometers are not accurate, don’t trust them, so we need to check them.
Do you trust your thermometer is accurate? I don’t, because they are not always accurate.
So you need to 'Calibrate’ your thermometer to assess its level of accuracy.
I will use centigrade because its easier (You can use google to convert to Fahrenheit)
First use crushed ice water left for a bit - that should be Zero centigrade,
Then use boiling water which is always 100 centigrade.
If you have readings that are above or below this, you know if your thermometer is not 100% accurate or by how much its out above or below true temperatures.
(the food industry is required to do this monthly to ensure their thermometer are giving true readings and have to replace them if not) Even if they are to begin with, they do change over time,
To be honest, our modern digital thermometers are not that accurate,
I have many all with with a few degrees difference in reading.
Actually, scientific laboratory mercury old school thermometers are more accurate and keep accuracy longer, but are still not prefect…
