Example Input: I'm presently on a diet and I was at my Fresh and Easy Neighborhood Grocery looking over possible diet foods. I wanted things that were tasty, non-fat and low in calories. I came home with about a dozen items. That's how I discovered the Tillen Farms Pickled Crispy Asparagus. Well, I've always liked asparagus anyway and I've enjoyed several brands of pickled asparagus. This Tillen Farms brand is really, really good! It's the best I can recall. There's an excellent flavor and a big clove of garlic down in the bottom of the jar which I'm looking forward to eating. I can't believe how good this asparagus tastes and right on the front it says "only 60 calories per jar!" Now this is my idea of a good diet food! Gary Peterson

Example Input: This was a weird drink - I had high expectations, but the flavor was just odd - it really did taste like fizzy Tang drink mix. However, my kids really liked it, and I think it is a great alternative to junky soda, so I will most likely buy more - but not for ME to drink. ;)

Example Input: My daughter has been GF for about 4 years now. We have discovered that if the main ingredient is rice flour, it usually isn't any good. It is usually grainy. This isn't the case with this product. It makes fantastic pancakes (the rest of the family would eat them). She didn't like the biscuits so we won't make those again. We used it to make corn dogs and the entire family (and a friend) ate them. No one even noticed. Everyone LOVED them. Amazon has since taken this off of the Subscribe and Save. I am so mad. I hope they put it back on soon.
