What You'll Learn
Using an infrared thermometer
An infrared thermometer is a handy tool to measure the temperature of a pan. It is a convenient and easy-to-use device that can provide accurate temperature readings in a matter of seconds, making it a popular tool for cooking and monitoring food temperatures.
- Prepare the pan: If you are not cooking with liquids, add a light coating of oil or a non-stick spray to the inside of the pan. A thin film of oil helps to get an accurate reading as oil emits infrared at a known rate, whereas different metals have different emissivities.
- Heat the pan: Place the pan on a grill or heat source and allow it to heat up.
- Point the infrared thermometer: Once the oil has heated up, point the infrared thermometer directly at the oil or the desired area of measurement. Avoid using it on a dry, shiny stainless steel pan as it can yield inaccurate readings.
- Read the temperature: Hold the thermometer steady for a few seconds until a temperature reading appears on the display.
- Adjust emissivity (if needed): If your infrared thermometer has adjustable emissivity settings, you can change it to match the surface you are measuring. This will provide more accurate results.
Infrared thermometers are ideal for situations where direct contact with the surface is impractical or dangerous. They can measure surface temperatures quickly and from a distance, making them a valuable tool in various industries, including cooking, food service, and manufacturing.
With an infrared thermometer, you can measure the temperature of not just pans but also liquids, such as soups, stews, milk, and melted butter mixtures. Additionally, it can be used to check the temperature of pizza stones, cookie sheets, and bread dough, ensuring that your food is cooked perfectly every time.

Water drop test
The water drop test is a method used to determine the temperature of a pan without a thermometer. It is particularly useful for stainless steel pans. Here is a step-by-step guide on how to perform the water drop test:
Firstly, heat the pan over medium-high heat. It is important to note that the pan should be heated without any oil or cooking fat. Once the pan is heated, add a few drops of water to the pan. Observe the behaviour of the water droplets. If the water evaporates quickly, the pan is not hot enough. If the water forms many bubbles immediately, the pan is too hot.
The ideal temperature is achieved when the water forms a single ball that rolls around the pan before evaporating. This is known as the Leidenfrost effect. The Leidenfrost effect occurs when the pan reaches a certain temperature, causing the water droplet to levitate and move around the pan. This temperature is typically in the high 300s Fahrenheit.
It is important to note that the water drop test may not always provide an accurate indication of the pan's temperature. The distribution of heat across the pan can vary, especially with low-quality stainless steel pans. Additionally, different foods absorb heat at different rates, so it is essential to pay attention to the appearance and sound of the food while cooking.
For a more precise measurement, it is recommended to use a thermometer, such as a regular or infrared thermometer.

Ice cube test
The ice cube test is a simple and effective way to check if your pan is at the right temperature before adding ingredients. It involves placing an ice cube in the pan and waiting for it to melt and evaporate. When the ice cube is gone, the pan is at the perfect temperature for cooking.
Firstly, heat your pan over medium heat for a few minutes. Then, drop an ice cube into the pan. If the ice cube melts and evaporates within 5-7 seconds, the pan is at the right temperature for sautéing. If it takes longer than that, the pan is not hot enough. If the ice cube evaporates too quickly, the pan is too hot, so lower the heat and wait a minute before trying again.
The ice cube trick is a foolproof way to ensure your pan is at the perfect temperature for sautéing, searing, stir-frying, and pan-frying. This is important because cooking at the right temperature can greatly affect the outcome of your dish.
The ice cube test also demonstrates the effectiveness of even heat distribution and thin sidewalls for faster heat transfer. This is particularly useful for soups and sauces.

Listen for the sizzle
When cooking, it's important to get the right temperature for your pan. While infrared thermometers are a great way to get an exact temperature reading, they are not always readily available. So, what do you do when you need to measure the temperature of your pan without a thermometer? One way is to listen for the sizzle.
First, it's important to understand the Leidenfrost effect. This is when a drop of water put into a hot pan no longer immediately evaporates but forms a ball that glides on the surface of the pan. The Leidenfrost effect typically occurs at around 190 °C (374 °F). However, this temperature can vary depending on the properties of the surface and any impurities in the water. Therefore, while the Leidenfrost effect can indicate that your pan is hot, it does not provide a precise temperature reading.
Instead, you can sprinkle a few drops of water onto the surface of the pan. If the water sizzles and evaporates immediately, the pan is hot enough for cooking. If the water just sits there, the pan needs to be heated up more. This method is simple and effective, but it may not be suitable for non-stick pans, as you should avoid heating them without any oil or water inside.
Additionally, you can listen for the sizzle when adding food to the pan. After you've added a bit of oil, touch the food to the pan. If you hear a sizzle, it's ready to go. If not, pull the food back and wait a few more minutes for the pan to heat up. This technique ensures that your pan is at the right temperature for searing or stir-frying, preventing your food from sticking to the pan.
In conclusion, while there are various methods to measure pan temperature without a thermometer, listening for the sizzle is a straightforward and effective approach. By sprinkling water or adding food to the pan, you can gauge the temperature and achieve the desired cooking results. However, for more precise temperature measurements, an infrared thermometer is a valuable tool to consider investing in.

Use a regular food thermometer
If you want to measure the temperature of your pan, a regular food thermometer will do the job. You can use a traditional probe thermometer to determine the internal temperature of your food. Stir your food and then insert the probe into the centre of the food or liquid, making sure to suspend the probe tip above the bottom of the pan. Pull the probe tip up through the food to find the lowest temperature reading. This will give you a more accurate picture of the product in the pan as a whole. Remember to stir your food often to ensure a more uniform temperature.
You can also use a regular food thermometer to measure the temperature of the pan itself. Rest the probe tip on the bottom of the pan to show the temperature of the pan. However, this may not be the best method as you are cooking food, not the pan.
If you are cooking anything delicate, such as eggs and fish, it is important to know the temperature of your pan. The temperature of the pan will determine how your food ends up tasting, as well as affecting the way it looks and smells.
If you don't have a thermometer, there are other ways to gauge the temperature of your pan. One way is to listen for the sizzle when you add food to the pan. If you don't hear a sizzle, the pan isn't hot enough yet. Another way to test the temperature is to use the Leidenfrost effect. As the pan heats up, a drop of water will form a ball that glides on the surface of the pan. This occurs at around 190 °C (374 °F). You can also try the water drop test: if drops of water skitter over the surface, your pan is in the high 300s.
