Rinse the Mung Dal then transfer to a heavy based saucepan. Add enough water to cover the lentils, then add in 2 tsp of turmeric, 1 garlic clove, 2 teaspoons of oil and the green chilli. Stir to mix then bring to boil on medium heat. Once boiled, turn down the heat and simmer the dal till soft. Keep an eye on the Dal just in case it goes dry and skim off any white scum that forms.

Heat 2 tablespoons of ghee in another large saucepan and then add in Spice A (tempering spices). Let it infuse for a few seconds then add in Spice B; stir continuously so it doesn't stick to the pan. Once fragrant, add in Spice C and continue stirring till the curry paste is cooked and the oil has separated.

Add the spice paste to the cooked dal and add in the potatoes and 2 cups of water. Bring to boil on high heat. Once boiled, turn down the heat and simmer till potatoes are half cooked. Add in the rest of the vegetables, coconut milk, tamarind juice and salt. Bring to boil again and simmer till vegetables are softened. If the Dal is too thick, add in the last cup of water. If you are happy with the texture of your Dalcha, leave it out

Finally, add in the coriander leaves, check for seasoning and turn the heat off. Enjoy
