Well I have blind tested the rice and taken a few pics at timed intervals. I am rather pleased with the results and also quite surprised.
I cooked the rice straight from the bag in boiling water without rinsing with the total cooking time 10 mins.
The rice Kohinoor Gold XL Basmati 5kg. The grain size raw is on average between 8-9mm the colour in the picture is slightly darker than it is in normal light. Added to the boiling water I then timed it and tested at regular intervals.
At 6m30s Pic#4 it was just off being cooked. If I were to keep it warm in the pan, this is the point I would remove it from the heat to allow it to sit in the pan lid on having been drained. Grain size now reaching 11mm.
At 8mins Pic#5 the rice is cooked perfectly and the grain size on average is 12mm. Its light and fluffy without any undue starch. This the point I would remove the rice normally.
At 10mins Pic#6 the rice has reached the manufactures recommended cooking. I was surprised as I expected the rice to sticky and and quite mushy. However, it remained light and once rinsed in boiling water was as perfect as you would want it. The grain sized varied but on average was 12-13mm.
What I have learnt is that soaking is not a requirement and really nor is rinsing but I do intend to continue the test by soaking the rice for the required 20-30 mins as per instructions.
However, presoaking the rice as I did originally, reduced the length of time required to cook it and helped to increase the grain size and made it lighter still.
Until my soak test, I can only conclude that there is a balance but the test will prove this, with this particular rice anyway.
