Chop the pumpkins into small pieces so that it is quicker to cook.
Remove the heads of the prawns, deshell and de vien them. Wash and clean thoroughly and then keep them aside.
In a frying pan, take a tbsp of butter and when it melts, add the prawns. Saute the prawns lightly (about a couple of minutes). Using a slotted spoon, take the prawns out and keep them aside.
In the same pan, add another tbsp of butter. When it melts, add 3 tbsp of chopped garlic. Lightly fry the garlic but don't burn them.
Add the chopped pumpkins. Add the turmeric powder, red chili powder, some salt and stir.
Fry the pumpkins for a while and then cover and cook. It takes about 20 minutes for the pumpkins to become soft.
When the pumpkins have become completely soft, add the sauteed prawns.
In another skillet, take a tbsp of butter and when it becomes a little hot, add a tbsp of chopped garlic and the chopped dried red chili. Watch the red chili turn to brown and then drizzle the entire thing on top of the pumpkin and prawns.
Mix it all together. Add more salt if required. Your filling is ready.
Let it cool down before you start using it.
