Heat oil in a medium saucepan or kadhai and add 1 teaspoon cumin seeds. When the color changes slightly add ½ teaspoon hing, 2 dry red chilies, grated ginger, and grated garlic. Fry on low flame till garlic and ginger slightly change color and the raw smell disappears. This will take less than a minute.
Now add chopped onion and saute well till soft and light brown in color. To this add 1 green chili with a slit, chopped potatoes, ½ teaspoon turmeric powder, ½ teaspoon coriander powder, ½ teaspoon chili powder, 1 tablespoon Kasuri methi, salt, lemon juice and mix well.
Finally, add 3 cups of chopped fresh methi leaves and 1 cup of water.
Cover and cook till potatoes are fully done. This will take around 10 minutes of slow cooking.
Serve hot with parathas or Rotis.
