in my opinion these are heads and twos above any pickle that you normally find at your local grocery store. a lot of nice, sweet, pickle flavor. I probably won't buy again off of amazon because of shipping charges, but if i ever see them locally, i'll buy a bunch.

Ex Output:
Positive

These chips are pretty delicious.. Even the original flavor with nothing on it is good. It's not as delicious as Doritos, but it's also not fried either, which definitely balances it out. A good snack for all times of day!

Positive

We use this flour for pancakes, muffins, biscuits and more. I have found that this mix works great in all my old regular bisquick recipes. We find the flavor to be similar to wheat flour. We have subbed this flour into several wheat flour cookie recipes, leaving out the leavening called for, and only one has turned out unsatisfactorily, but not inedible. Definitely convenient and more affordable to our family of seven to be able to purchase in bulk.

Positive
