"Orange Marmalade: Take the cleanest Sevilla oranges that can be obtained. Cut them in two, take out all the pulp and juice, carefully removing all the seeds and white skin, and put it into a basin. Boil the rinds in hard water until they are tender, changing the water two or three times while they are boiling; then pound them in a marble mortar* and add to them the juice and pulp. Put the whole into a preserving pan with double the weight of sugar. Set over a slow fire, boil it 35 minutes, then put it into a jar with brandy paper over. *Or cut them into strips or pieces."
