Has anyone ever made these? They're just little clumps of freshly grated
parmesan, cheddar or other cheese baked on parchment or silicone until they
melt down to a crisp circle.

I've never made them on purpose but sometimes by accident when some cheese
melts off onto the baking sheet or even the plate in the microwave!

I saw an ad for a company that makes them and they were charging something
like $18 per box. Didn't say how many ounces were in there but didn't look
like a lot. Robbers they are!

If you did make them... What did you do with the leftovers? Refrigerate?
Or would that make them soggy? Will they keep at room temp.? Looks like
the ones they are selling are boxed and sold at room temp.

I did buy some of these for Angela at the gluten free store but they weren't
that expensive. Still expensive I feel for the amount we got. She thought
they were okay but wasn't really thrilled. I think hers had an herb in them
or maybe it was black pepper. She would probably like the plain ones.
