Ingredients: 5lb marrow, free from pith and skin, 5lb sugar, 2 large lemons, 2oz bruised ginger, ¼ teaspoon cayenne. Cut the marrow into little lumps about 1 inch long and ½ inch thick. Put them into the preserving pan. After the sugar has been melted in as much water as will cover the bottom of the pan, add the juice and rind of lemons, ginger and cayenne, tied in a muslin bag. Boil all steadily for one hour. This is best made in September.
