Ingredients
Method
1.Combine yoghurt, sugar, zest, juice, egg whites and honey in a large jug. Mix well. Transfer to the chilled bowl of an ice-cream churn . Churn 40-50 minutes, until thickened and starting to set.
2.Pour into a 1.5L freezer-proof container. Freeze 4 hours or overnight, until firm.
3.Arrange biscuits on tray, drizzle with liqueur, set aside. In a large bowl, whip cream until soft peaks form. Fold in custard and marshmallows.
4.Spoon half the cream mixture among six 1½-cup glasses. Crumble half a biscuit into each glass with half the coconut. Top with a scoop of frozen yoghurt. Repeat layers. Serve straight away.
If you don’t have an ice-cream churn, freeze yoghurt mixture until semi-frozen, process to break up ice crystals then refreeze until required.
