- Clean, wash and soak the dals and rice in enough water for at least 4-5 hours. 
- Rinse and drain and blend into a smooth mixture. 
- Transfer the mixture into a wide bowl, add curd, mix and let it ferment overnight.  
- Preheat the oven to 180 Deg C. 
- Add the grated bottle gourd, 1 tsp oil, lemon juice, salt, red chilli, turmeric, ginger, garlic and mix well.  
- Now add the Soda-Bi-Carb and give a quick mix. 
- Transfer it into a greased baking dish. Do grease the muffins tins all over as sometimes it becomes difficult to remove. (I used a 6 inch cake tin, and a muffin tin.) 
- Fill the tin only half way, i.e. around 1 inch from the base. 
- In another pan, add the remaining oil, once hot, add the mustard seeds, carom seeds and sesame seeds. Once it pops up, add the hing and switch of the gas. 
- Pour this tadka or the oil mix over the tin. 
- Bake it in a preheated oven at 180 Dec C for 30-40 mins until golden brown on the top and a toothpick inserted comes out clean. 
- The muffins are ready in 25-30 mins, the cake takes around 45 mins. 
- Once done let it cool in the tin for at least 5 minutes on a cooling rack before removing them out. 
- Serve them warm with chutney or tea
