Orange Jelly. No. 1.
Squeeze the juice of nine or ten China oranges and one Seville orange through a sieve into an earthen pan, adding a quarter of a pound of double-refined sugar. Take an ounce and a half, good weight, of the best isinglass, the peel of seven of the oranges grated, and the bitter squeezed out through a towel; boil this peel in the isinglass, which must be put over the fire in about a pint of water just to melt it. Stir it all the time it is on the fire; strain and pour it to the juice of the oranges, which boil together for about ten minutes. When you take it off, strain it again, and put it into moulds.
