Ways to avoid wasting heat while cooking

It turns out that the most time-consuming part of the process is not the movement of boiling heat to the center of each small bean or noodle, which takes only a few minutes, but the movement of moisture, which can take hours. Grains and dry legumes therefore cook much faster if they have been soaked. However heretical it may sound to soak dried pasta, doing so can cut its cooking time by two-thirds — and eliminates the problem of dry noodles getting stuck to each other as they slide into the pot.
