Can I use parboiled basmati rice just like ordinary non-converted basmati? tl;dr Do the cooking time, behavior, taste, and texture of parboiled rice differ significantly enough from non-converted rice such that a simple substitution will yield undesirable results? 

I accidentally purchased a large bag of parboiled basmati rice. I make a variety of dishes with basmati rice, but I've never tried any of them with the parboiled version. Can I just use the parboiled rice in place of the non-parboiled? Or do I need to make various adjustments to cooking times, steps in a recipe, methods, etc? And will the results (taste, texture) be different from non-parboiled even with said adjustments?

For example, here is my basic basmati rice recipe, which I make in a pressure cooker. Will this recipe work with parboiled?


Rinse 1 cup rice until it runs clear
Let drain ~15 minutes in colander
Heat 1 tbsp oil or ghee in pressure cooker
When hot, sauté the rice for a minute or so
Add 1.5 cups of water or vegetable stock
Close pressure cooker lid and wait for full (high) pressure
Manually pressure cook for four minutes.
Let pressure come down naturally
Fluff and serve.


Also, the directions on the bag say to soak the parboiled rice for an hour before cooking. I don't typically have the time for this: the whole point of rice is that it's easy and quick to make. But plenty of recipes using basmati, including ones for just plain basmati by itself (i.e., white rice with no added meats or veggies, as in the preparation above), ask for the rice to be soaked, and I never do; I just wash it and let it drain for about 15 minutes. Is soaking de rigeur for parboiled?

Finally,  I'm worried that cooking times for more elaborate dishes will be thrown off by the parboiled rice, resulting in unevenly-cooked mixtures of rice, veggies, spices, and (on the rare occasions I cook it) meat; and that the resulting dish will be significantly altered in taste and texture as a result of using the parboiled rice instead of white. 

Are these concerns valid?
Parboiled rice should be cooked more or less the same way, but may come out a little less sticky than regular rice. It should taste exactly the same. Your recipes should work just fine. 

I would probably do a trial run with a quick batch of the plain rice as you would normally do it just to make sure since parboiling as a process is different in different parts of the world.

Good luck!
