I used grated cheese (cheddar with a bit of parmesan) and cooked them in the oven for my first attempt. Did have to blot on paper towels because of the grease but yummy. Wish I'd known about the parchment paper then.

Once the crisps cooled I put them in a tupperware container but for any length of time, I'd probably keep them in the fridge.

I am now thinking up variations - a bit of cayenne pepper or ground chili maybe. Perhaps some minced garlic or onion.
