These are delicious crackers, but don't ship well, and many end up broken in the process.

I grew up on orange sodas and thought this might be like a 'healthy' Crush. That would be a NO. Of course, tangerine has a bit of a different taste than orange as it's that much sweeter. Adding the carbonation to it just made it an unappealing fizzy, ultra sweet drink, not unlike cough syrup. Proceed with caution. Perhaps kids would find it super tasty.

I have used and liked Sugar in the Raw for many years, after being introduced to it in a Starbucks. My most recent purchase, however, was disappointing. The sugar was lighter in color and had a crystal size maybe 1/4th of the regular size. Having large crystals was something I always really liked about Sugar in the Raw. It enhanced the quality of mixed drinks and of lattes. I called their hotline to complain and was told that they had had a problem with their recent sugar crop and that the result was less molasses in the sugar. They have had many complaints of a similar nature. This, they claimed, also reduced the crystal size. They said this problem should go away with their newer crop. The representative said that the new-crop sugar will have a 6-10 digit date code (without ANY spaces) that ends with a "1" and no letters. The trailing digits are a date code using the Julian calendar. (My recent bad-purchase had a space after the initial sequence of numbers and then ended with a "51A"). Bottom line: their current product is not much better than much cheaper products. When they get a better crop, I'll go back to purchasing Sugar in the Raw.
