Hated olives for my entire life untill my wife let me taste some lettinos. Those where amazing most kalamata olives are great and tasty aswell avoid those from the supermarket though they seem to be soaked in preservatives.
There is a world of quality differences in olives. The ones who are not homogeneous of color seem to be ages over time instead of with acid.
Watch the docter stone anime, it’s quite amusing. TL.DW super dude get petrified for like 3000 years and wakes up and re-introduces technology.
