The worst part of eating boiled eggs is peeling the clingy eggshells off. This "bumper car" method of cooking boiled eggs makes several delicious eggs at once and also gets the shells off quickly, so that once you're done shaking the eggs, the peels almost fall off themselves.
Jackie Brown, writing on the Mom on a Mission blog, details the method. It starts with putting eggs in a pot of with a pinch of bicarb soda or salt, bringing it to a rolling boil, then removing it from the heat for 15 minutes. (This, by the way, is similar to Alton Brown's method of making perfectly boiled eggs, except he uses different timing, and he doesn't continue on to shake the eggs.)
Then quickly cool off the eggs with ice and water and — here's the novel part — shake the pan so the eggs gently bump each other. For best results, use older eggs, and check out the full post for other tips and full details.
Of course, for single servings of boiled eggs you could just skip the peeling altogether and cut through the egg or blow on one end of an egg to get it out of its shell, but for a big batch this method can save you the effort of peeling each egg or having to invest in a pressure cooker for easy-to-peel boiled eggs.
