I use 3 cups of rice to cook for my family of 6. I don't know how much it weighs, but the TMX basket isn't big enough. We do have a small amount of leftovers, which get eaten the next day.
I also boil the kettle to get hot water to cook pasta. It didn't make sense to me to use the TMX for however many minutes to get hot water. Either that or I start with hot tap water.
