The waterlogged bottom problem
Why rice is wet at the bottom — water distribution failure
A pot of rice where the top layer is perfectly cooked but the bottom is waterlogged and gummy is a water distribution problem — too much water pooled at the bottom relative to the rice depth, or the heat was too high causing steam to escape before the bottom water was absorbed. This is especially common with small quantities of rice in a large pot.
The Fix
How to fix wet-bottom rice
- Remove from heat, tilt the pot gently to pour off any visible pooled water
- Replace lid with a cloth-wrapped lid and rest on lowest heat for 5 minutes — steam dries the bottom
- Spread on a wide tray in a thin layer — evaporation from the surface dries waterlogged bottom rice
- Prevention: use the correct pot size for the rice quantity — rice should fill the pot at least 1/3 deep
- Reduce water by 2 tablespoons if cooking small quantities in a large pot — less rice means less absorption per unit of water
The Science
Why does pot size affect rice cooking?
In a large pot with a small rice quantity, the water layer relative to the rice depth is proportionally much higher than in a correctly sized pot. Steam pressure in the headspace is also lower — less rice means less steam generation, so the steam environment above the rice is less pressurised. Both effects reduce absorption efficiency and leave more water pooled at the bottom.
