The ratio of popcorn to oil in a popcorn machine varies depending on the machine and the type of popcorn being used. However, the general rule of thumb is to use approximately three tablespoons of popcorn to one tablespoon of oil.
To make popcorn in a popcorn machine, you can fill the kettle with the appropriate amount of oil and turn the machine on to heat the oil. Once the oil is hot, add the popcorn kernels, making sure that they are evenly distributed in the kettle. Place the lid on the kettle and wait for the popcorn to start popping.
During the popping process, make sure to move the kettle around gently to ensure that all kernels are being popped and none gets burned. Once the popping stops or slows down significantly, switch off the machine and remove the kettle. Be careful not to touch the kettle's hot surface as it can cause burns.
Overall, using the appropriate ratio of popcorn to oil is crucial to make popcorn in a popcorn machine. It would help if you always followed the manufacturer's instructions for the machine you're using, which will typically include the recommended ratios and instructions for safe and effective usage.
