The last bag of these I got from Amazon had a lot of hollow bisquits. It was weird ...... they just weren't solid like they should be. I'm going to switch to another brand of grain-free dog bisquits now as there's no sense in paying for something I'm not getting (and these are expensive!) And if it wasn't for the good packaging I'd wonder if bugs had gotten to them..... but I don't think that's possible.

I used this mix to make a 9x13 cake in a glass pan using grapeseed oil, spring water, and free range eggs. I thought the cake had a nice flavor to it but it was not what I was expecting. I was craving a white cake (like wedding cake) and went to my local store to find something wheat-free, gluten-free and dairy-free; I purchased this vanilla cake mix. I think it is a very good mix. I couldn't really taste the vanilla flavor but thought it had a nice flavor. The cake is yellow, dense (but not like a pound cake) and texture-y like brown rice has more texture than white rice. I thought the sweetness was just right. I think I would purchase again but would make pineapple upside down cake with it.

I like all the varieties except the salt and pepper. They taste too much like black pepper and nothing else. The others are very goodl<a href="http://www.amazon.com/gp/product/B001RVFDOO">Popchips 6-Flavor Variety Pack, 0.8-Ounce Single Serve Bags (Pack of 24)</a>
