refamiliarizing myself with the self-healing cookbook, i decided to cook up some azuki beans. one half-hour into their simmer they should be cold shocked.
listening to the beans boil against the pot, i was enjoying the rhythm in which they scraped against the metal vessel. as if the bubbles rattling the beans were coming from a bellows. the sound of submerged, scraping beans was padded with the quiet rumble of escaping vapor.
the balance changed over time (as the beans soften, the high-tones degrade). slowly, the highs muted away until finally, the sound of bean scraping metal was gone. then i looked at the time and saw it was the half-hour point. which made me wonder if this was how the half-hour point was chosen.
