You mentioned cooking jasmine rice using a 1:1 ratio of water to rice, but rice generally can't be cooked using a linear ratio like this. As you increase the amount of rice being cooked, and change the size/shape of the cooking vessel, more of the water will be lost as steam. It's easiest to use a rice cooker, which will allow you more flexibility with regards to how much water/rice you used, but if you don't have a rice cooker (or anything that can work as a rice cooker) then I'd recommend the method where you cook the rice in a covered dish in the oven.

I wanted to demonstrate that it can be simple, but you are right there are a lot of variables, but I think they are small. The size/type of pot you use may affect water amounts.

But I found it very useful to learn to cook with whatever you have available to you. And then learn to adjust. All of these things take tiny amounts of time and yield great results. (mainly through practice of course)

OP didn't say anything about ratios or scaling, just offered 1c rice as that's generally enough for 2-3 servings at a time. And it just happens that 1c water is generally the right amount for this and is easy to remember.

Good advice on the water. Similar to how people learn ovens, it helps to learn pans. The best method I've tried so far is a ~2:1 ratio (adjust to desired texture) in a 14" wide, lidded, enameled skillet. I'll try the oven again soon to compare, but that particular pan on a stovetop is hard to beat. Learn your pans.

That is a good point. I have often found the temperatures in recipes to not work great with my combination of pots and pans and need to tweak.

But you only get to the tweak stage after you start trying to cook at all. (a lot of people don't cook much or try to make meals they think are out of their reach)

The rice cooker is easiest, but there's another scheme: use an abundance of water and cook the rice like spaghetti. I learned the technique from a Lynne Rossetto Kasper cookbook, and it's never failed me.

I had never heard of cooking rice like pasta before. (going to try it next time I cook rice, thanks!) I think this is a good example of a small piece of knowledge that can possibly have a larger effect.

You can completely use a linear ratio. Google any world class chef's recommendations, they will all recommend a fixed ratio e.g.:

Rice cooker instructions also use a liner ratio.

Cooking rice isn't rocket science.

Given ordinary cookware, and picking a pot that's not completely out of proportion to the rice, the 1:1 works just fine. You don't lose steam (well, not much) because the lid stays on. Takes 20 minutes, pretty much without fail.

Yes, you can get more complex. Maybe it even produces better rice. But the secret to homecooked meals is - for most people - simplicity :)

As I understand, cooking rice usually has a constant amount of water lost to steam. You need to have a rough idea of how much water your rice actually needs to absorb and how much is lost to steam. In my experience with my setup, rice usually requires an equal volume of water and 1 lost 1 cup of water to steam. So 1 cup of water requires 2 cups of water, 2 cups of rice requires 3 cups of water, etc.

So y = x + 1 where y is the cups of water and x is the cups of rice. 1 is the number of cups lost as steam.

Each time you open the lid you lose steam, so you may have to take that into account. I use a rice cooker and don't open the lid so I don't worry about that though.

Water lost to steam heavily depends on style of cooking, or more precisely, in a covered pot, is mostly a linear function of the excess heat beyond that required to bring contents to boiling temperature (steam re-condensation on the lid/sides provides a slight buffer) + a bit lost to empty space in the pot (when opening etc).

Some stoves are hard to regulate so the food is just barely boiling, so it can be hard not to notably lose water.

From experience, the boiling of water in itself is mostly meaningless when cooking, unless you want food extra shredded. You can happily cook at 90℃ or 80℃ if you want, but it will take longer.

Note if cooking risky food: beware of required time at a given temperature to kill pathogens, not forgetting heat transfer takes time especially in solid chunks.

In general, a rice cooker is indispensable and costs about $30. Plus you can walk away from it as it cooks, and you can put things on top of the rice to steam in there as well. (It will impart flavor though, so maybe don’t put greens in there unless you want broccoli-water flavored rice.)

you guys are doing it all wrong. take it from us Asian folks. it's called the finger test. the amount of water above the rice should come up to the first line on your finger as you're touching the rice. yes you have to stick your finger in the pot.

having grown up where our main staple was rice, my parents never made burnt or soggy rice. oh and having a rice cooker prob helped as well.
