Key ideas in Mastering the Japanese Kitchen
- Excess surface starch causes rice to become gummy and stick together
- Washing removes the powder left over from the milling process
- Soaking allows water to penetrate to the core of the grain
- Heat hardens the outside of the grain before the center can hydrate if not pre-soaked
- The purpose of washing rice until the water is clear
- The impact of skipping the soaking step on rice texture
- New crop rice requires slightly less water because it retains internal moisture
- The standard ratio is roughly 1.1 to 1.2 parts water to 1 part rice
- Residual steam finishes cooking the core of the grains
- Lifting the lid lets out the heat and moisture needed for the final 'steam' phase
- Steaming creates a specific 'plump' texture
- Calculating water ratios for new vs. old crop rice
- Boiling without soaking/steaming results in uneven cooking
- The importance of keeping the lid on during the resting phase
- Fluffing (shari-kiri) redistributes moisture
- Distinguishing between boiled, steamed, and overcooked rice
