Ingredients

1. Vadas - as per your requirement
2. Sambar of your choice

Method

1. First put the hot sambar in any bowl you like to serve.
2. Put the hot vadas as many you can soak in the bowl.
3. Close the lid for few minutes and keep it aside.
4. After few minutes can turn it and keep it aside.
5. Soak until your vadas are soft and juicy.
6. Serve it hot and eat it hot. You can put a tsp of ghee (clarified butter) on top of the soaked vadas.

Notes

1. In hotels, as per my knowledge, they do not soak it directly. They first soak it in water, squeeze the water from the vadas, then add the vadas to the sambar. I believe that all the flavour and taste of vadas can come out in the water.
2. Vadas should be soaked in sambar when both are hot, then it will become soft sooner.
3. You can make plain vadas or can make vegetable vadas as per your taste to soak in the sambar.
4. When the vadas are soaked in sambar, the sambar can get reduced as the vadas will absorb the liquid. So always add enough quantity of sambar to the vadas.
