Soy sauce from the Bluegrass Soy Sauce Co., which the bottle tells me is the only small batch soy sauce company in the US! I actually use a lot of soy sauce instead of salt when I cook, since I think it adds a deeper flavor. This was the first gift I opened (intrigued by the fact that it was wrapped in a ziplock), and could tell just by it that the entire gift was going to be good.
