I remember the official menu when British Prime Minister, Theresa May visited India. Jackfruit Biriyani was one of the dishes.
It’s now popular across the world, that jackfruit is officially a health food.
Apparently, raw jackfruit is a taste substitute for meat and thus ideal for a vegetarian or vegan alternative for biriyani, cutlets, burgers etc.
I did the Dum process also with saffron, Rose water and milk. It came out well.
The recipe I used is here.
