One of the problems with other people is that they have different food preferences than you do.
This can be a benefit if the food in question is something you can purchase in small quantities or that doesn’t go bad, because then you can buy it for yourself and have no competition from eating it. But it’s problematic if it’s something that you can’t share and will thus go to waste if you get too much of it. If the other people in the household are vocal about their distaste, then you might not get/make the item unless the loudest is not there for whatever reason. (A reason our family orders Hawaiian pizza only when DH is away on business.)
I really like grapefruit juice, but I’m the only one in the house who does, so I can’t drink an entire carton before it goes bad. I do, however, order it whenever I see fresh squeezed on the menu at a bunch place.
The rest of the family doesn’t mind beets, but I’m the only one who really loves them.
DH rarely gets to eat Brussels sprouts because the rest of the family ranges from meh to yuck. DC1 used to love sardines but has outgrown them (the cats got almost an entire tin the day DC1 discovered zie no longer wants to eat them, but they have been missing out on smaller amounts since).
#2’s husband is a vegetarian, so… meat. Especially bacon. He’s not that enthusiastic about pesto or soup, but he’ll eat it if it’s there.
What food do you love that nobody else likes?
