"If you’re wondering what could be especially difficult about boiling an egg, you should have heard her. The Flaw — the unappetizing probability of either a chalky yolk or a runny white — occurs because the yolk gets cooked before the white, and the desired temperature window turns out to be harrowingly small, so the ideal preparation must set the white while leaving the yolk custardy, and not do it too rapidly. Oh, and tossing a fridge-temperature egg into boiling water will cause the air inside to expand and sometimes crack it, and apparently no two cooks can agree on exactly what simmering means, and third, the number of eggs must be compensated for by adjusting the amount of boiling water to keep cooking time constant. Geary recited further facts imperiling the P.S.B.E., and after a while the difficulty of boiling an egg at home with anything like success sounded to be on the order of a bone-marrow transplant. This appeared to please everyone, particularly Kimball, and the meeting moved on to Dressing Up Meatloaf."
