Of course, teaching cooking is true, but you have to make appropriate adjustments according to your personal preferences. The dishes are not necessarily delicious, which is why many people who follow the video to learn to cook like to say "it's useless at first sight". The reason is that it has not been improved to suit your own taste.

I have to say that cooking is really a science, and patience and carefulness are indispensable if you want to do it well.
