Citrus And Ginger Marmalade - cooking recipe

Ingredients

2 medium grapefruits, scrubbed
3 large oranges, scrubbed
3 large limes, scrubbed
1 piece (8 inches) fresh ginger, peeled, cut into matchsticks
4 lbs plus 6 oz granulated sugar

Preparation

Thinly slice peel from grapefruit; cut into thin strips. Remove pith from grapefruit. Reserve half of the pith and chop coarsely. Chop grapefruit flesh into 3/4 inch pieces. Remove and reserve seeds with the pith. Cut oranges and limes in half vertically. Thinly slice the fruit, reserving seeds.
Place sliced and chopped fruit and grapefruit peel in a large bowl. Tie reserved seeds and grapefruit pith in a piece of muslin to make a small bundle. Add to fruit with 6 cups warm water. Cover and let stand overnight.
Place fruit mixture, pith bundle and ginger in a large heavy-bottomed saucepan on medium heat. Bring to a boil. Reduce heat to low; cover and simmer for 25-30 mins or until peel softens. Using tongs, discard pith bundle.
Add sugar to fruit mixture. Cook and stir for 5 mins or until sugar dissolves. Bring to a boil. Boil uncovered, stirring occasionally, for 45-50 mins or until marmalade sets when tested.
Ladle marmalade into hot sterilized jars; seal immediately. Cool to room temperature. Label, date, then store in a cool place.
