Example Input: I don't know why this flour isn't available in grocery stores in the Midwest.  Typical grocer flours have a protein content much too high to give an authentic taste to such foods as pizza crust and homemade pastas.  And after years of making homemade pastas and trying to find that perfect recipe that would result in those served in the best Italian restaurants in the US and Europe, I'm happy to discover, the secret was in the 00 protein content all along.  What a fabulous difference this flour makes!  Freezes well too.

Example Input: When I got my Keurig brewer last month, I bought two different types of hot chocolate.  The Grove Square Hot Chocolate is far superior.  I have so far brewed it on 6oz and 8oz with good flavor at both sizes.  The flavor is rich and it leaves no residue in the bottom of the kcup (the other brand does, maybe I got a bad batch?).  Overall, I will happily buy this one again.

Example Input: My husband and I are not coffee drinkers, but we love hot chocolate. We hated the time it took to heat up the water,and the mess the dry mix sometimes makes. We saw that the Keurig coffee maker did other things like hot chocolate and tea, liked that it was almost instant hot water, and bought one. I ordered another brand of hot chocolate k-cup, and absolutely hated it. It had a weird almost metallic taste that was not sweet or chocolately. I was worried I wasted my money on a maker I would never use. I decided to try another brand and purchased the Cafe Escapes Dark Chocolate Cocoa, and we absolutely love it! It is sweet and chocolately without being too bitter(which is why I originally steered away from the dark chocolate). I fully recommend this product!!
