This is a really close copy of an amazing Japanese sauce that I just love!!! The servings estimate was hard to guess. It depends on how much you like. I tried and tried to find a good recipe online and ended up playing with a couple of them to come up with this. I would try this over almost anything or as a dip for any meat, fondue, Shabu Shabu, etc. It is intended to dip grilled steak into. Enjoy!
