0 carbs in pork scratchings
(Here we call them "pork rinds.)
I also like cheese crisps (all cheese, I buy a brand from Italy called Grok Si . They only contain cheese (grana padano).
Apparently you make your own. I've been experimenting with this recipe.

(If they are bendy, they haven't been cooked long enough or not sliced think enough.) You can also use little mounds of grated cheese. (Don't use preshredded cheese, they put cornstarch in it which isn't good for us, grate or shred your own.) I've been microwaving each one 1-2 minutes (depends on your microwave) , blotting off any extra grease & refrigerating before eating. (I prefer a small quantity.) I've tried both cheddar and parmesan, My homemade ones aren't as crunchy as the store bought ones (parmesan is crisper.)
