EGG

Оглавление

Egg is protein. All protein hardens above boiling point. Although egg is often given a blast of fierce heat we usually eat them only partly cooked. Omelettes, scrambled eggs, poached eggs, boiled eggs are given just enough heat to make them firm. Cook them longer and you’ll find yourself in the plastics industry.

High temperature releases hydrogen sulphide (from the sulphur in the egg-white) and makes an egg taste stale. This same sulphur combines with iron in the yolk to make that grey ring round the yolk of a hard-boiled egg that has been made too hot. So you see that a real boiled egg is unattractive, indigestible and tastes disgusting.

Although a ‘boiled egg’ goes into boiling water, do not bring it back to boiling point. Keep the water well below boiling temperature so that the surface just moves (the French say frémir which means to shiver and perfectly describes it). The water is now at about 185ºF.

The most satisfactory way to cook the egg in its shell is the old-fashioned method of ‘coddling’. Bring a pint of water to maximum boil. This rolling confusion of water, changing to steam, is nearly at 212ºF. Put one egg into the water, put a lid on the saucepan and turn off the heat. After approximately six minutes, eat it. I say approximately because the freshness of the egg influences the cooking time, and you might need to modify your cooking times to find the right one for your eggs, and your taste. Measure the amount of water you use, and provide one pint of water per egg. And from now onwards, remember how to estimate water temperature.


The egg is also a liaison, used, as flour is, to bind liquids into a sauce. But while flour is tough enough to withstand boiling, the protein of the egg curdles at 167ºF., and your sauce collapses. So when there is egg in your sauce be cautious. Heat it gently, and if possible cook it in a double-boiler (a basin over a saucepan of water will do). But there is a way of cheating – add a trace of flour to the egg and the sauce will withstand boiling, if you bring it to the boil slowly.
