This is pretty good regular style soy sauce.  But it is not super-wonderful-better than any other good quality soy sauce you can buy in an Asian market.  The main value is as a unique gift.   In the Japanese soy sauce world, there are 4 types: regular, mild (usukuchi), for raw fish (sashimi) and light colored.  Bluegrass soy sauce is regular style.  Compared to Kikoman (a good commercial brand that is widely available) Bluegrass starts saltier, is flat in the middle, then ends with a complex & interesting flavor.  Kikoman is less salty initially and has a round, full flavor in the middle.  Doesn't have the complex ending flavors.  For me, the initial saltiness of Bluegrass is a minus and Kikoman's full middle flavor is a plus.  I prefere Kikoman, especially for dipping sushi where the flavor is more direct.  But I lived in Japan for many years and am used to the standard Japanese flavor.  I haven't tried Bluegrass blended in other food as a background flavor, which is how soy sauce is usually used.   Bluegrass is a perfectly good soy sauce.  Each brand has a different flavor and everyone has their favorite.  If you want a unique Kentucky gift for an Asian friend, this is different than the standard bottle of Bourbon or box of chocolate.

I am in the health food industry and I am gluten intolerant.  I have tried many different GF cookies in the last ten years.  I bought a box of Lucy's chocolate chip cookies last night at Safeway.  I was not impressed.  The cookie was dry, almost to the point of being stale. This is a common problem when people try to make a gluten free cookie that have no experience in baking with gluten free flours.  Lucy's cookies remind me of Pamela's cookies which are also dry.  Being dry is not a sin that a little milk or coffee can not take care of.  However what I cannot stand is an after taste.  The base flour combination has an odd after taste that spoiled the little enjoyment I had from this cookie.  I looked at the ingredients and found garbonzo and fava bean flours.  I cannot recommend this cookie based upon the after taste.  I have not tried the other varieties that may have stronger flavors to cover up the after taste.  I would suggest either Udi's frozen cookies or Glutino cookies.  I find these two brands superior to Lucy's.  Thanks for reading.
