Rasp very slightly on a fine and delicately clean grater the rinds of some sound Seville oranges; cut them in quarters, and separate the flesh from the rinds; then with the small end of a tea, or egg spoon, clear it entirely from the pips, and from the loose inner skin and film. Put the rinds into a large quantity of cold water, and change it when they have boiled about twenty minutes. As soon as they are perfectly tender lift them out, and drain them on a sieve; slice them thin, and add eight ounces of them to each pound of the pulp and juice, with a pound and a half of highly-refined sugar in fine powder; boil the marmalade quickly for half an hour, skim it well, and turn it into the jars. This marmalade has hot a very powerful flavour of the orange-rind. When more of this is liked, either leave a portion of the fruit unrasped, or mix with the preserve some of the zest which has been grated off, allowing for it its weight of sugar. Or proceed thus: allow to a dozen Seville oranges two fine juicy lemons, and take the weight of the whole in sifted sugar, of excellent quality.
With a sharp knife cut through the rinds just deep enough to allow them to be stripped off in quarters with the end of a spoon, and throw them for a night into plenty of cold spring-water; on the following morning boil them sufficiently tender to allow the head of a pin to pierce them easily; then drain them well, let them cool, and scrape out the white part of the rind, and cut the remainder into thin chips. In the mean time have tie pulp of the fruit quite cleared from the pips and film; put it with the sugar and chips into a preserving-pan, heat it slowly, then boil it from twenty to thirty minutes: it will be very rich, good marmalade. The sugar, first broken into large lumps, is sometimes made into a very thick syrup, with so much water only as will just dissolve it; the pulp and juice are in that case boiled in it quickly for ten minutes before the chips are added; and a part of these are pounded and stirred into the preserve with the others. March is the proper month for making this preserve, the Seville orange being then in perfection. For lemon marmalade proceed exactly in the same manner as for this.
The whole of the rinds of cither fruit are pounded to a paste, and then boiled with the pulp, to make what is called transparent marmalade.
