To make Buttered Eggs

To prepare your own buttered eggs, it is essential to have freshly laid eggs from directly underneath a hen. The eggs must still be warm or the preservation process won't work. A warm new-laid egg still has a slightly porous shell, so the softened butter is able to permeate the shell and completely seal it from oxygen. Use salted butter for best results.

To butter eggs, have butter at room temperature and rub it gently but completely into each warm egg using your hands. Be sure to really massage it into each egg for best results, using your hands to gently smooth off the excess butter and transfer it to the next egg. Store the eggs in regular egg cartons in a very cool place (the cellar of your Irish cottage is ideal). Buttered eggs keep for up to six months.
