If you do not have thickened milk, prepare it first by boiling down ½ liter of whole fat milk until it is reduced by about half. Reincorporate any cream skin formed on top and stuck to the sides of the pan while the milk is still hot. Allow to cool.
Note that thickened milk can always be substituted for thick coconut milk or coconut cream, to make this vegan.
Peel the mango and extract the pulp, adding no water.
Mash the bananas and the jackfruits and add to the mango pulp. You can use a mixie if you wish, but this is best done by hands to retain some of the fruit’s original texture.
If the jackfruit is not soft enough to mash, cook it briefly with a little water and pulse this to a rough puree. Cool completely before adding to the other fruits.
Sugar is optional in this recipe; the sweetness of the combined fruits should be more than sufficient. But if you’re adding any, do it now.
Add the thickened milk, and the cardamom-nutmeg powders.
Chill well.
When ready to serve, prepare the nuts. In a tempering pan, heat the ghee, toast the almonds and pour over the mukkani payasam. To make this vegan, you can simply toast the nuts and add them – don’t substitute the ghee for oil.
