Egg subsitute and rice milk when combined in the standard proportions for pancake mix make a substance that is probably patentable as a new glue. Non-stick pans don’t stand a chance….
Once the pancake is removed from the pan (throw that pan out by the way, no dishwasher is up to the task, and life’s too short to scrub that hard) put straight in the bin.
Under no circumstances try to ingest aforementioned substance.
