What makes rice come out chewy and how do you prevent it?
I use par-boiled long grain rice, and DO NOT pre-soak or rinse it.  Put your rice into a good heavy based pan, add about three times as much cold water and bring to the boil, yes, you can stir it once or twice if you want.  Boil for about a minute or two, turn off the heat, leave the lid on and wait about 30 mins (some times it might be up to 45 mins), the rice cooks very nicely.  Strain and use as required.  This always for me makes perfect fluffy non sticky rice - I have never had an issue with rice with this method. Of course this is for par-boiled long grain rice, other types of rice might act differently.
