This is a summary of japanese soy based dipping sauces. I’m summarizing from Makkiko’s most excellent justhungry.com japanese food blog. Go there…its phenomenal and much more indepth.
Qasabi Jo-yu: Wasabi and soy sauce – raw fish, sushi
Sho-ga Jo-yu: Ginger and soy sauce – used for oily raw fish like mackerel, and bonito.
Ninniku Jo-yu: Garlic + soy sauce – used sometimes for meat.
Karashi Jo-yu: Reconstituted mustard powder and soy sauce – this was revelation for me – Makiko reports that this is a very popular combination that is used for things ranging from steamed pork buns to meats. As suggested we used an English mustard powder, Keens, and a touch of wasabi and it was THE BOMB!
Not sure what its called but: Chili and soy sauce – gyoza dumplings and we put it on the meat..mmmm.
Su-jo-yu: Vinegar and soy sauce – used for many things, cuts the greasiness of fatty dishes. We did not make this but I know it from eating Japanese.
Ponzu: Citrus juice – yuzu, lime, lemon – and soy sauce – used for many things. We used some dashi in this to cut the saltiness a bit.
Tsuyu: Dashi stock, mirin and/or sake, sugar, and soy sauce – Noodles, tempura, etc.
