I'm British and I don't have a rice cooker. They take up space etc when it's really easy to do easy cook basmati in a saucepan or wok in twenty minutes.
I didn't even know that rice cookers existed until uni, then I had like 7 in my kitchen.
I'm half Italian and half Eritrean.
No rice cooker, I use the ordinary pot.
I'd never used one until I spent some time living in Japan. After returning to England, it was one of my first purchases. Couldn't live without one now. I eat a hell of a lot of rice. They make quick lunches/dinners incredibly easy, as you can put more than the rice in them. Throw some meat and veg in there as well and you've got an entire meal in one pot, with minimal effort.
We have two, one for family meals which we make 3-4 cups of rice in and one that we bring out for large gatherings (30-60 people) and it can make 16 cups at a time. My siblings also had ones that they took to uni that makes one cup of rice at a time. Very convenient for certain types of rice but others do taste better made in a pot!
Iraqi, and we eat rice with nearly every meal.
P.S. We've had so many rice cookers over the years that we've accumulated 8 rice paddles that come with each of the rice cookers 😂
