To Determine perfect amount of water to cook rice..
You must determine the water loss due to cooking time. This must be done experimentally.
The formula serves as a guide as to the baseline of water needed assuming 0%-evaporative loss.
w = r(p-s)/(1-p)w = r(p-0.12)/(1-p)
r : weight of rice (g)s : % moisture level of uncooked rice (may assume 0.12)
p : % final hydration level, ideally between (0.58 and 0.64)<-- your choice
w : volume of additional water (g or ml)Pre-soaking
An overnight experiment to find necessary PRE-soaking time for rice..
It is necessary to pre-soak, pre-hydrate rice, because this greatly improves the evenness of the rice texture after cooking.
The purpose is.. too long... is a waste of time.. too short and you don't get max pre-hydration.
soaked (minutes) vs % increase
in water weight.
2x overnight bowls,___________30% and 33%
SO it seems maximum rice soaking peaks @ about 1 hour..
No need to soak for Overnight folks..
