Roast and coarsely grind the cumin and fennel seeds together.
Drain the water from the split pea lentils and red chillies. Add it to your food processor bowl.
Pulse together the split peas and red chillies in the food processor until the mixture resembles a bread crumb texture.
Empty the mixture into a large bowl. Add in the green chilli, salt sugar, cumin and fennel powder, ginger and garlic paste, onion, spring onion, coriander and baking powder if using
Use a spatula and combine everything well together.
You want to create a mixture of the kind that when you hold the mixture into the palm of your hands, you’re able to form a ball.
Place a tablespoon of the mixture into the palm of your hand and pat it flat. It should be round, smaller than your palm and about 5mm in thickness. Make a dent in the centre almost like the hole in a donut.
Try to keep the vadas all the same size.
Fry in hot oil until reddish brown in colour. The mixture is loose and crumbly so take care when placing it in the oil.
Turn the vada once over during cooking and place onto an absorbent paper towel to drain any excess oil.
It usually takes between 2-3 minutes to cook depending on the heat of the oil.
Best served hot.
