English Amber Marmalade

Shave 1 orange, 1 lemon, 1 grape fruit very thin, rejecting nothing but seeds and cores.

Measure the fruit and add to it three times the quantity of water. Let stand in an earthen dish all night. The next morning boil 10 minutes. Let this stand another night and the second morning add pint for pint of sugar and boil steadily until it jellies, which is usually more than an hour.
