Juice of 1 large ruby grapefruitor approx 240ml/1 cup of store-bought juice
60ml(¼ cup) vodka
360ml(1 ½ cups) red or pink prosecco
Candied grapefruit slices to decorateto make these, sprinkle small slices of grapefruit with light brown sugar, then grill/broil or dry fry on a high heat for 1-2 minutes, turning once until lightly caramelised. Leave to cool for a few minutes before making a small slit in the grapefruit slice and placing on the rim of the glass.
Pour the sugar on a flat plate. Dip the rim of the glasses in grapefruit juice, then dip in the sugar to give each glass a sugar-rim.
Pour the remaining grapefruit juice, vodka and ice into a blender. Blend until the mixture turns to slush. You may need to scrape down the sides a couple of times.
Spoon the slush mixture into the four glasses and top with the pink prosecco.
Decorate the glasses with a slice of candied grapefruit and serve immediately.
Nutritional Information is per serving, without the candied grapefruit slices.
