Indeed, I have personally tried CozyMeals, which appears to be the prominent online platform for remote cooking instruction that you mentioned. They provide virtual live cooking classes as well as private 1-on-1 sessions. According to a reviewer's feedback on the live cooking class, it is advisable to have all the ingredients prepped, measured, and ready before the class begins, as the instructor progresses swiftly through each preparation step. While it is possible to ask questions, the overall concept remains similar: you observe them, but they are not observing you, which falls short of the guided instructions I previously mentioned. Opting for their private 1-on-1 cooking class, which costs approximately $300, allows you to simply watch as they handle all the prep work and cooking.
