I’ve never tried caviar but some friends of mine have. As the team was leaving Tehran in 1975, some of the teamies bought some from the individual vendors hanging around the departure concourse at Mehrabad, so they could eat caviar and not eat the PANAM lunch.
I’ve tried caviar a few times in my life. It’s salty (I don’t mind the salt) but kinda ‘pops’ in your mouth - don’t like it.
During those times I’d imagine wasn’t expensive there. Caviar typically has always been more popular around the Northern provinces of the Persian side of the Caspian Sea.
Well, airplane food is not my favorite either.
