I see this on menus regularly around Suffolk but a google search doesn't bring up much about this dish other than linking to an afghan style dish.

I'm hoping someone may know more about this and have a recipe. It's fairly sweet but not at Korma style levels and has dessicated coconut as a main component.

One recipe describes it as follows and it has a red/orangey appearance so I assume tomato is key ingredient too.
simmered in thick sauce of coconut desiccated powder, fresh blended mixed fruit sweetener, sultanas & nuts

From the description, it sounds like it could have a spoon or so of red masala paste added made with fruit cocktail.

Have you bought and ate a few of these?
You could describe it more, as it maybe just a chefs made up dish.

Peshwari is famous in BIR for being a filling for sweet Naan Bread

The BIR curry can be on the same theme, derived from the Persian and Moglai/Mogul
set of rich creamy mild dishes with nuts and wet/dried fruits.

I think DalPuri is onto something here, I hadn't seen that recipe before but will give it a go - the colour, consistency etc all look like something that would go into this curry.

I have tried it a few times from various places and the consistent thing is that it's not overly creamy.
