Pressure cookers aside, to make a more or less traditional risotto in a more or less traditional way.
Here are Ten Rules to Better Risotto:
First: You want to use a very starchy rice that will result in a creamy risotto. The three best are probably "arborio" and "carnaroli" from Italy, and "CalRose" from California. Personally, I prefer CalRose, but the Italian rices are obviously the traditional choices.
Second: If everything goes as it should, you'll use a little bit less than 3.5X the amount of stock and wine (by volume) as you will of rice. Therefore, you want to start with about about 4X times more stock -- just to be on the safe side. If you need more fluid, you can always switch to water. Once the stock is in the rice, you've got the stock flavor. A little water won't hurt.
Third: You want to hold your stock hot, so that when you do add more stock from time to time, you won't drop the temperatures drastically.
Fourth: You may hold your stock covered, so that it doesn't evaporate while the rice cooks, but the rice must be cooked uncovered.
Fifth: DO NOT STIR CONSTANTLY. The idea is to get the rice creamy, not gooey. If you stir too much the rice will break up and become a glue-much. Thanks but no thanks.
Sixth: You want your risotto to ride the edge between a fast simmer and a bare boil. You want to see the occasional bubble, but not a rolling boil. On almost every stove, medium-high is too high for the bulk of the cooking (but maybe not to get the first quanta of stock going); medium-low is probably just right. Remember, too cold and too hot -- both have consequences. You want the Goldilocks' "just right." Glass top stoves can be difficult because they're so slow to adjust.
Seventh: There's a cooking acronym: BTABRTAS. It means, bring to a boil, reduce to a simmer. Refer to step Sixth.
Eighth: Add stock as needed ("PRN" in medical jargon). If you're cooking risotto in small enough quantities to feed less than an army, that usually means by the 1/2 cupful and not the cupful. Add it when you can see naked rice at the top. You want to keep adding in small quantities so that the rice isn't swamped or parched when it's finished.
Ninth: Stir just before and after you add stock. Stir enough to keep the rice from sticking, but not much more than that. When the rice is almost done it will start appearing creamy. It's done when it's almost done, not when you run out of stock. How do you know it's almost done? Taste it. When it's almost done, stop adding stock, turn off the flame and stir a few times. Why almost done? Because when it tastes done, it will go to overdone off the flame, while you're plating it. It's a delicate thing. Soft enough to be comfort food, but not muchy. Creamy not gooey.
Ten: So eat already!
