In this case, IR thermometer makes it easier to be sure that the meat is ready. It can only measure outer surface temperature. If you want to take internal one, cut open the meat to do so.
Besides, IR thermometer is also helpful in grilling.
In several Asian countries, to temper spices is common technique in cooking. It means, the chefs heat up oil/butter to a very high temperature. Afterward add spices, which release their natural flavors. The process is called making tadka.
Tadka is an onomatopoeic word for crunching sound of spices.
Yet, this process is little difficult. It needs to get the oil sufficiently hot for actual tempering. But, if you heat it too much, the tadka might burn. In this regard, you can take several readings with IR Thermometer. These readings make you sure the oil is hot enough. This happens up to 200⁰C . At this temperature, reduce the heat to avoid oil to get hotter.
Yeast for bread / Home preparing drink:
This one is the original reason why I love to use IR Thermometers. We all know, the yeast needs particular temperature to grow. If the temperature gets too hot, yeast will die. Infrared Thermometer is ideal to proof yeast in bread. You can also dive the yeast while making a home preparing drink.
