All them that have said no to spuds you do realise you can no longer have crisps !
Genuinely I can’t remember the last time I ate crisps. I don’t think it was in 2020. I wouldn’t even notice if I never ate crisps again.
Do loads of people only ever eat plain, boiled rice or something? Rice is really, really versatile. You’ve got all the different kinds with different properties and textures: I have several different kinds of rice in the house at all times (basmati, Jasmine, and Korean short grain, but others depending on what I’m making - Thai sticky rice, for example).
You can cook and flavour it in so many different ways: risotto, paella, pilau, dirty rice, green Mexican style rice, rice and peas, jollof rice, fried rice, congee, arancini and so on and so on. That’s not anywhere near an exhaustive list. You can use it to stuff things (not just vegetables, it’s great stuffed inside tiny chickens in samgyetang for example). It can be savoury or sweet (there are loads of rice pudding variations you can make as well as other rice based things, like mochi). It can be ground up and made into noodles or flour.
Honestly, I think rice is possibly more versatile than potatoes.
I’d definitely choose rice.
