i will get back to you on the rice wine vinegar-it has a taste that’s kinda’ strange. personally i’m more partial to malt vinegar on fries but RWVinegar has it’s own applications.
I have a Filipina friend who says they use rice wine (not rice wine vinegar) in their Chinese dishes. they marinate the meat with the wine and oyster sauce. (the wine is acidic, so I see how that works)
