Heat the Paniyaram pan on medium heat . Add around ½ tsp of oil into each round section. Once the oil is hot, carefully add 1-2 tbsp of batter into each section. Each section should be ¾th full.
Cover the pan with a lid . Let it cook on medium low heat for 4-5 minutes until the vada are lightly golden on the bottom. Then slowly flip them over using skewer or chopstick and cook on the other side for 3-4 minutes.
Once done take them out on a plate and repeat the same process for rest of the batter.
Take 4 cups of warm water in a big bowl. Add salt and a pinch of hing to the water. Next add all the vada to the warm water. ( if you are planning to freeze the vada , don't soak in water - see notes ) Let the vadas soak for 20-30 minutes.
In another bowl, whisk the yogurt with salt and sugar to a smooth pourable consistency. If yogurt is very thick , add little water to it.
After the soaking time, take one vada onto your palm ,then gently squeeze all the water by pressing between your palms. Make sure not to press the vada too hard. Line them in a large serving plate.
Repeat the process with rest of the vadas. Pour the prepared yogurt on the vadas so the vadas are submerged in yogurt.
Sprinkle red chilli powder, roasted cumin powder and refrigerate for 2-3 hours.
When ready to serve, drizzle tamarind chutney, coriander chutney, chopped fresh coriander, thin sev ,pomegranate arils and masala boondi. You can always top with more yogurt because vadas soak yogurt when resting.
Enjoy!
