I’m not sure what you think about the recipes you find on the internet. Many food bloggers find recipes they like and re-share them. Some develop recipes and share them right away. Coming from the culinary industry, I have been a part of a culture that develops recipes and passes them on verbally, chef to chef. We don’t stop cooking to write something down; we tell each other. And that is how you end up with some meals on your plate when you go out to eat. The cook making that food learned it from the guy standing next to him, who learned it from a chef, and so on.
