I saw this video on YouTube and could not understand how the milk doesn’t boil over like it does when I make chai on the stovetop. I intuitively feel it has to do with steaming versus direct heat, but I’d like to have a better understanding. Even if it’s just a concept I can look up and read about, I’d appreciate it. Just something to point me in the right direction.
Edit: In the video, water, milk, and tea leaves are placed in a stainless steel container. That container is then propped up inside an Instant Pot and steamed under pressure for two minutes.
