From the above I’ve got a list of all those I’d choose never to round to for a rice based meal.
A rice cooker (or a decent steamer) has a one great advantage – one the rice is cooked – it never overcooks.
So you time the rice to be cooked early (it sits hot and happy for ages) as you continue cooking the curry or whatever.
IME almost everyone in asia uses one (or a steamer) – using saucepans is for gypsies.
I cant recommend one particular model though. All the popular ones have unpronouncable names. A veg steamer does a proper good job though.
