Being a minute late is too much sometimes. I used to have to "learn" how to cook a new bag because the grains are different sizes, sometimes it's not really brown or white but white-brown or brown-white. The best Japanese rice is in my opinion, from California. I like Koda Farms, their brown rice is just about as close as you can get to the flavor of white rice while having a decent amount of nutrition. Fun fact, the "flower name" for America is 米国. Means rice country. Nowadays people just say Amerika in Katakana which technically has a kanji representation as 亜米利加 but even that has the word rice in it. China calls us 美利坚合众国, which means beautiful country.
It's not difficult to eyeball what it takes to make good rice. Quick and dirty rule is having just enough water to cover the rice. I just stick my pinky in and measure up to the second phalange. You basically just heat until it boils, quickly escape the air, release to mid heat and then keep an eye on it for about 10-15 minutes without opening the lid. If your technique is good, you can kind of estimate how long it takes on a linear scale for cups to cooking time. A clear lid helps, it'll just look right. Key thing to do is take your rice spatula and just carve out the edges when it's done so you're getting a more consistent mix.
Later in life, I got the 1.8L Neuro Fuzzy Rice Cooker by Zojirushi. I fell in love with the name, which is apparently from artificial intelligence. Not sure how they come up with that.
Here's the thing: sure, it's easy to make one kind of rice and costs almost nothing to do. With a dedicated rice cooker though, I can make any kind of rice, in any amount, without having to think about it. The inside of the pot has markers for your rice quantity and water volume for each type. I have the larger cooker, so it kind of takes longer (it consistently takes one hour to cook about 3-4 cups, which is simple to plan around). There's a quick cook setting which makes no discernible difference in consistency. Every time I turn it on, it sings a cute little song and then sings another one when it's done. I find it utterly delightful.
Here's why you get a rice cooker. Sure, you can make rice in like 15 minutes on the stove. But then what do you do if you have leftovers? Put them in the fridge where it gets stale? With a rice cooker, I make 5-6 cups at the beginning of the week, and I can leave it there for at least 72 hours and it stays incredibly fresh. I wouldn't recommend it, but I've left it in there for 4 days. Constant heat kills any bacteria or mold that might take.
I don't have to worry about my rice technique. I don't have to worry about storing and heating leftovers. I can make as much rice as I want and save myself time and effort throughout the week. If I wanted to be even more efficient, I could let the rice soak overnight, and set a timer for it to start cooking right before I wake up. It's one less thing to worry about, and I can time all of my meals around it so that everything's ready at the same time.
You can also make other things besides rice such as pancakes or pasta in it. Pasta's a bit more difficult, but I've made perfect pancakes in this thing.
Highly recommend Zojirushi for their excellent insulation products.
