A lot of their recipes use ginger and garlic, anything fries is normally breaded with corn starch. They also use it to thicken up sauces. Basically anywhere you would normally use flour, use corn starch instead.
Absence of sanitation … I had a recipe for Chinese red sauce that you keep reusing. You cook chicken in it and save the sauce in the fridge for next time, perpetually. The recipe did suggest boiling it pretty good before each use, just in case. Still surprised it didn’t become a mold experiment.when i worked for Procter&Gamble,
we had a restaurant product that the Chinese liked.
i have been in too many Chinese kitchens and have seen their "secrets" :
the absence of basic sanitation methods and disregard for child labor laws.
