Oh yes, we had a thermometer, that’s the only way I knew that it was taking so long to get to the correct temp. :)
Well,I don’t have any experience with outdoor grilling; and certainly deep-frying over propane would be a ‘bridge too far’ for me ;-)
But the potstickers turn out pretty good, with a little experience, on the kitchen stove or in an electric fryer.
