Preserved Citrox
Ingredients
Directions
Boil the citron in water until clear and soft enough to pierce with a fork.
Remove the citron and place it in a syrup made of sugar and water.
Boil until the sugar has penetrated the citron.
Remove and spread on dishes to dry slowly, sprinkling with powdered sugar and turning until dried.
Pack in jars or boxes with sugar between the layers.
