I was happily surprised with this product. I read other negative reviews and was honestly disappointed in Betty Crocker gf cake mix so I didn't feel the need to try this. I finally bought it at a whim when I saw it at my local market and I am happy I did. I am a baker at heart and love to spoil my family with homemade deserts and pancakes on the weekends. I have adjusted my cooking and baking to primarily gf for the past year now and am happy when I find a gf alternative that cooks & tastes like "the real thing". Another plus is that I can buy this at my local market (which does not carry too many specialty foods) and don't have to make the extra trip to the higher end store.  I made pancakes today and they were a hit with everyone. Will definitely use it to try other recipes. Only downside is the cost and size of box; very pricey and very small.

Here's a tiny consolation: easy Thai barbecued chicken! Cut your usual fryer in quarters, cook it slowly over charcoal or quickly in a hot oven, and then brush it generously with "sweet chili sauce" and cook it just a few minutes more. Most authentic with 'sticky' rice but also delicious with brown or red rice.  In Thailand, people squat over hibachi-sized braziers on the sidewalks and sell portion of this sort of barbecued chicken. Sometimes they trot alongside inter-city buses as they pull into stations, and sell chicken through the windows. Don't be squeamish! This is a treat you'll remember. The same sauce will enhance the flavor of any fowl from blackbird to condor or whooping crane.

I'm very picky when it comes to chips. I've gone through so many, but this one really hits the spot. It has just the right amount of crunch, with just the right amount of flavor. It's also great to know that you're not eating something that's bad for you. With 100 calories a pack, it's definitely the ideal snack!
