Yes, I think I was fussy but I also think I just didn’t like what was being served that much. My mum did all the cooking and was very, very traditional. Very British and basic cooking - nothing that involved garlic or spices or depth of flavour, and certainly nothing that wasnt traditionally British.
For example, I was at university before I had pasta, pizza, curries etc.
I cook pretty much everything from scratch and there is very little that I don’t like now. 12yo Ds is the same. I make Moroccan tagines, Thai curries, Indian curries and sides, paella, loads of pasta dishes etc. As do most people, I’d imagine.
Perversely, it is my parents who seem fussy to my DS as my dad won’t eat garlic or any spice whatsoever (rules out so many things) and my mum won’t eat shellfish or pasta or anything Thai (random).
