Pineapple and Grapefruit Frappe

Ingredients

• 2 ripe pineapples, peeled and roughly chopped
• 3 grapefruits, halved and juiced
• Sugar, to taste

Directions

Whizz up the pineapple in a liquidizer until smooth and pass through a course sieve. Add the grapefruit juice and stir in sugar to taste, remembering that the sweetness from the sugar will lessen slightly when frozen, so to use a touch more than you normally would. Place in the freezer for around 2 1/2 hours to set, stirring every 45 minutes.
