Ex Input:
This is a good idea in theory but doesn't work well in practical application.  The things do not all cook property.  About half of them are puffed, some are partially puffed and the rest won't puff no matter how much you cook them.  I follow instructions, measure and have a good microwave.  I usually have to cook twice as long as stated to get any puffing at all.  The flavor is ok but just awful compared to commercial pork rinds purchased in the grocery store.  I also end up with very little that I can eat out of a batch.  They also taste just awful.

I bought these at walmart for less then $2.00 dollars a box.There over  $2.80 a box @Amazon for (box of six).Then you need to add another $7.00 dollars to your order to get free shipping ....I would not buy these again could be better if you added chicken or an egg like other reviewers mentioned. My box does say gluten free so maybe there are 2 versions.

I've tried a few different Hot Cocoa brands for my Keurig... And have been disappointed EVERY time, until now! Cocoa brews smooth and full flavored-on either the small cup size or the medium! I add a splash of almond milk and I'm ready to go :) Perfect! I'll definitely buy this again.
