For starters, I'm not salt or msg averse. I enjoy salty food like chips, jerky, and bacon. However, these pork rinds are ridiculously salty tasting. To give you a better idea of what I'm referring to, Kettle Chips Sea Salt variety have 55 mg of salt per 1/2 oz of chips. Lowrey's pork rinds have 310 mg of sodium per 1/2 oz serving. That's roughly six times the salt content of a food considered relatively salty by most people. I read a review on here saying that they were too salty and decided to order them anyway thinking the reviewer was some salt hating baby. Boy, was I mistaken. I wish I hadn't ordered these.

Ew...I love Canada Dry and Schwepps, and I decided to try this brand because it was cheaper and it looked authentic. Not sure how the regular (non-diet) kind compares, but this tastes so diety--it's gross. I usually drink diet soda and don't mind the taste of diet coke, diet dr. pepper, diet sprite, (other diet gingerale, too) but this is REALLY GROSS. don't get it! You can definitely taste the ginger, but the overly saccharine taste ruins it.

This is my favorite K-cup coffee (I've tried about twenty different types) and, so far, everyone I've served it to really likes it a lot. Even the pickiest coffee connoisseur I know thought this k-cup made an excellent cup of coffee. Two non-coffee drinking friends wish they liked coffee because they love the sound of Caribou Mahogany.
