- 3 lge grapefruit (800 gms)
- 600 gms sugar
Boil the grapefruit for 30 minutes, drain, then allow to cool.
Cut grapefruit in half then into fine or chunky slices, as you prefer.
Weigh the fruit then add three-quarters of its weight in sugar (3 grapefruit should give you about 800 gms of fruit, requiring 600 gms of sugar).
Place in a large saucepan and heat slowly until the sugar melts, stirring continuously. Simmer for 40 minutes, stirring, or until the marmalade starts to jell.
Pour into hot, clean jars and seal. Makes about three 400 gm jars.
