Polos is one of my favorite dishes. But for Sri Lankans living abroad, it is hard to come by. There canned Jack fruit products available in most countries. This recipe is uses these cans.

3 cans of Young Green Jack fruit
1 onion, chopped
1-2 green chillies
2 tsp garlic, chopped
2 tsp ginger, chopped
1 sprig of curry leaves (optional)
1-2 tsp chillie powder
1 tsp turmeric powder
2-3 tsp curry powder
3-4 cardamoms
3-4 cloves
1 inch� piece of cinnamon
2-3 pieces of goraka
1 can of coconut milk
salt to taste

Fry the onions, green chillies, ginger, garlic and curry leaves in about 1 tbsp of oil, till golden brown. Next add all the spices, fry for a minute for so till fragrant.
Now add the rest of ingredients, except coconut milk, stir to coat. Add salt.
* Transfer the mixture to a slow cooker, add coconut milk. Stir and cook on low heat for at least 6 hours. The curry would turn a dark brown color when done. (I usually let it cook over night)
Serve hot.
* You can cook this also in a pressure cooker. Cook for about 20-25 minutes at steady pressure (Since cooking times, vary depending on the type of cooker you have, use your judgment here)
** If you want to cook on the stove, cook under low heat in a heavy bottom pan.
