Example Input: I keep trying other brands.... cheaper brands. Stupid me! This ginger IS soooo worth the money. Tender, moist and never a let down.

Example Input: 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.

Example Input: The popchips are a nice alternative to potato chips. They are not greasy and only 100 calories per bag. Great for dieters. Fits in with a low calorie diet. Definitely would recommend trying at least once.
