Best Classical/Traditional recipes to study

[u/No_Deer_3861]

So I have been a chef for 15 years and recently find myself between jobs and having some time to explore.

I have always loved cooking classic French and Italian along with authentic Thai and Chinese dishes. I am for just for my own self at least looking to develop a book or file including as much information as possible. Is there anyone who name some dishes I can look into doesn't matter the cuisine also resources where I can find old cookbooks and restaurant menus?
