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.

These Backyard BBQ Kettle Chips were a great deal with the promo code.  It was nice to have a larger size bag.  Some Kettle Chips in the grocery store are only about 5 ounces and we polish them off in one family lunch!  They arrived fresh and were not in crumbles as some other chips from Amazon Grocery have been.  Great flavor and All Natural!

I grew up in Ohio and lived in the woods where sassafrass trees were plentiful. I would dig tender roots or "bark" a few trees for a delightful tea.  I purchased Breezy Morning Sassafrass tea and although was quite good it was very expensive for only 20 average size tea bags and shipping was as much as the product.  Not a good bargain.  I switched to Pappy's extract.
