My daughter in law brought some of this up from Lima Peru and we all loved the flavor. Its flavor is better than the soy sauce you buy in a store around here. Its simply the best.
I grew up consuming this soy sauce and now i can say that I took it for granted. I can't find another sillao with the same flavor and dark color as this one. All the American kikkoman brands taste terrible and the San-J tamari is bland with no color. Not even in Japan I found an "everyday" soy sauce I could buy at the mall and like flavor-wise (with the exception of very pricey ones that you can't buy on your regular grocery shopping trip). To put it simply, I can't eat any dish that requires soy sauce if I don't have Kiko Sillao by my side.
