Which one of your weird food sounds disgusting in the paper, but is actually good? And how have you discovered it?

So so bear with me. This one is mine You put mustard on white bread/or any bread. Then on it you put Ermine and also grease with mustard.

I was wondering what are your weird foods. How have you even discovered it? And how hiw others reacted first when they saw it. I found this one for example from my father and was meet with weird looks whenever I eat it.
