In a pressure cooker on medium heat, pressure cook lentil, water, coriander powder, garam masala, red chili powder, and tomato.
Wait for 4 whistles. The texture should be mushy. If the texture differs from the video, pressure cook for 2 more whistles. Remove lid (be sure to let the steam release completely--I prop up the safety valve with a knife).*
Turn the flame to the lowest setting while you prepare the Tarka.
In another pan, add oil, garlic cloves, red chilli flakes and red chilli powder and let cook on low heat for a few minutes or until garlic has turned golden brown.
Pour the Tarka in the hot daal, give it a quick stir and turn off the flame.
Cover with lid until ready to serve.
Serve hot with Basmati or any long-grain rice.
