Chinese potato (kooka-konkani, koorka-malayalam, sambrali-kannada) is a seasonal and very rare vegetable mostly available in South India. Unlike normal potato it is small and black in colour. Its black colour is due to the soil and dirt sticking on it. It is very tedious process to clean this vegetable, but you can really do that easily with a simple trick.
We are also using ash-gourd skin that is by product of other dish (kuvale sasam). Ash gourd is also called winter melon, it is actually a fruit but it is eaten as a vegetable. Ash gourd skin or peels are very low in calories; it is good for diabetic patients. It helps to improve digestive system, and it is very helpful cure for tapeworm.
Together this dish is packed with nutrition and lots of health benefits, let's start cooking then.
- Ash gourd skin (I used skin of ½ kg ash gourd which I used for another dish).
- Kooka or Chinese potato ¼ kg.
- Mustard seeds (raai) 1 tsp.
- Urad daal (split black gram or white lentils) 1 tsp.
- Curry leaves 1 stalk.
- Dry red chillies – 3 pieces (we will use the flakes).
- Coconut oil (most Konkani recipes are cooked in coconut oil) 3 tsp.
- Salt to taste.
- Grated coconut 1 tbsp. (this is used for garnishing).
- Water 1½ cup.
Before we start with the step by step method we have one thing to do, cleaning the Chinese potato. Cleaning this vegetable is a tedious task. Don't worry I have a trick for this task. Generally people avoid cooking this dish because of this problem; it is very hard to remove the black soil and dirt from this vegetable. You'll need a sack or an old bag to clean it.
You can see the steps in the picture below. I put the vegetables in an old bag and then gently crush and rub them against the floor, this removes the skin as well as dirt from them without making your hands dirty. This is a simple solution that my mother thought me. Once the dirt is removed we can then remove excess dirt with the help of a peeler or knife. Then I wash them in water.
Now that our main ingredients are ready to be cooked we may now move ahead with our step by step guide :)
- Chop the Ash Gourd skin and Chinese potato.
- Heat 3 tsp. coconut oil in an iron wok or a kadhai.
