Method
● Peel and slice the mangoes, discarding the stones. Put the slices in a medium-sized trifle bowl.
● In a large bowl, whip the cream until it's just holding its shape. Fold in the yoghurt and stir in the lime juice.
● Spoon the cream over the fruit, then sprinkle the sugar in a thin layer on top.
● Pop the dish into the fridge for 2–3 hours. It's ready when the sugar has dissolved on the surface and looks melted and gorgeously gooey.
