Clean and wash methi leaves 3-4 times till they become dirt free. Let them sit on a colander for 5 minutes.
Meanwhile, in a mixing bowl, add jowar flour, rice flour, baking soda, 1 tsp sesame seeds, chopped green chilies, ginger, garlic, turmeric powder, chili powder, salt, sugar, lemon juice, dahi, and 1 tsp oil.
Chop methi leaves and add them to the flour mixture and mix well.
Add some water little at a time and make a smooth dough. You may need more water depending on your flour and the wetness of the methi and yoghurt. Make two logs out of the dough.
In a steel container, add a few drops of oil and grease it well. Now keep the logs in the container.
In a pressure cooker, keep a stand or jaali which comes with the cooker. Add some water. Keep your steel container over it and close the pressure cooker lid without putting a whistle on it. Let it cook on medium-high heat for about 12-15 minutes.
Once ready, let the muthias cool down for for about 15 minutes. Cut them into 3/4 to 1 inch pieces.
In a skillet, brush the remaining 1 tsp oil, arrange the muthia pieces, and cook them on low-medium flame from both sides until they turn golden brown and crispy. Add 1 tsp sesame seeds 1 minute before taking the muthias out of the skillet.
Garnish the muthias with a few coriander leaves and serve.
