Puree the mayonnaise, yoghurt and mango chutney until the mixture is creamy. Mangochutney is usually chunky, so use a hand blender.
Finely dice the medium-sized onion and fold into the creamy mixture with the flaked almonds. Finally stir plenty of curry into the cream until it has turned a rich color. 2 to 3 tablespoons should be enough, if you like, take more!
The almond mango sauce keeps for 4-5 days in the refrigerator. Frozen longer, of course.
