Bad
Inedible. It's really bad. It doesn't taste like teriyaki at all. Furthermore, I can't even incorporate it into other dishes during cooking to prevent wasting it. I had to actually throw it away and I hate wastage. It's THAT bad.
Only tastes of vinegar
I don’t know how this manages to be so completely unlike teriyaki sauce, but it does. Whatever I’ve paired it with, it tastes like slightly sweetened vinegar: more like brown sauce than anything else. I’ve got a good sense of taste and no Covid, but there’s just no other flavours. I expected something rich and savoury alongside some sourness, but this sauce is so one-note I can’t believe it has multiple ingredients. I’ve tried adding other stuff to it, but no, my whole mouth tastes of vinegar. One to avoid. Those little individual pouches are infinitely better.
