cordelli

I believe it's Papadum

There are probably as many different recipes for making them as there are people making them

Many of the recipes I've seen for them when I was looking were of the type

1) buy package of papadum in Indian Grocery Store
2) Roast directly on a gas burner or on the grill till crispy

They are usually made with bean flour, which isn't that cheap, so it may be easier to just buy the package.
