[Q]: For those who love salt and vinegar potato chips, this is the one to choose. The flavor is zippy and tart, with no unpleasant chemical aftertaste like the less "natural" versions of this snack. The 2-ounce bags are just right to share at lunch. The chips are a little greasy, and that's why I've given them 4 stars instead of 5.
[A]: 4


[Q]: I went to 4 grocery stores looking for this flavor of Jello for my green tomato jam recipe and finally found it here. This jello is wonderful! Evidently it's only carried in the stores during the summer but with harvest time in the Fall, I couldn't find it anywhere in town. This Jello tastes like watermelon and the jam recipe I made with it takes like watermelon jam! Great made as regular Jello too. Yummy!

[Q]: Once or twice a year for a little variety and that's about enough for my cat of this particular variety.  He likes it for a change from his chicken, turkey and beef, but not very often.  He will eat about 3/4 of the can and then he's had enough. He's not a huge fish fan anyway, but this stuff looks to be about the best out there in the fish varieties.  The chunks are bit sized so if your cat has a small mouth like mine does, it will be easier to chew.  Don't know why my cat doesn't like this type of fish, but he really could care less about it.
