I probably wouldn't really count these are "real" poppadoms, they're poppadom inspired mostly potato based snacks[1], sold in the crisps isle.

Whilst "dried potatoes" are the top ingredient, they also contain plenty of corn, rice, and wheat products.
Surprisingly, I have found that in the States, the "purest" seeming snack food is Fritos Original Corn Chips:

"Ingredients: Corn, vegetable oil (corn and/or canola oil), and salt."
Some of you may have read my story of the Olive Section at Carrefour in Catalonia. The same thing had happened with the same friend when she visited me in Phoenix. She had heard tell of a vast selection of crisp flavours. So we went to the convenience store/Subway/gas station on the corner, where half of the store shelves are chips, dip, and salty snacks. She was impressed and chose two bags, including a chili lime flavour.
And here I sit with the Kalamata olives and the Manchego cheese. Jamón Serrano is not easy to come by; sometimes I settle for Prosciutto.
This sounds right up my aisle. Where can I find the story?
