2 cups water
1/4 cup caster sugar
1 tsp lemon zest
1/2 cup lemon juice
1/2 cup passionfruit pulp
Recipe
Place water, sugar and lemon zest in a heavy pot and boil for 10 minutes. Allow this to cool, then stir in the lemon juice and passionfruit pulp. Place in an icecream maker or churn by hand.
Churn every hour for a couple of hours, breaking up the solid crystals, then spoon into a plastic container and seal tight.
