A: Copper is classified as a metal on the periodic table and is therefore not classified according to family in the manner that plants and animals are. Copper is red-colored. It is malleable, ductile, and a good conductor of heat and electricity.
For a hard-boiled egg, start the egg in cold water and bring up to the boil. Once the water is gently boiling, set the timer for between 7-10 minutes depending on how well cooked you like your eggs. The longer you boil the egg, the firmer it will be. Once cooked, plunge the hard-boiled egg into plenty of cold water for one minute. Drain and cover with more cold water.
It takes 5 minutes for water (just enough to cover the eggs) to boil, at which time I turn the heat off and let the eggs sit for 5 minutes, making a perfect soft-boiled egg. I make a batch every week for my wife and myself. The oven method may result in eggs that are easier to peel, though. I havenât tried it.
