In a pot, heat oil, suatecumin and fenugreek seeds until you could smell flavours for about a minute.Add onions and green chillies fry till slightly golden. Add ginger and garlicpaste, red chilli powder, turmeric and salt. Add curry leaves as well if using.Fry this masala for 2-3 minutes until oil separates. Do not overcook theingredients. Once the oil starts to separate switch off the flame.
On the side, add 1 cup yoghurt to the gram flour and whisk it together.
Then add the rest of the yoghurt and about 6 cups of water (1 cup watermeasures 160ml). Mix it in nicely and pour it onto the fried masala.
Start the flame and keep stirring in. Continue to stir in until it comesto a boil (to avoid lumps). When the mixture starts boiling, turn the flame lowand let it simmer for at least an hour on a low to medium low flame until youget the right consistency.
We are looking for a runnygravy consistency because it gets thickened once the fritters are dipped in. Itgets thicker when cools down. You will also see sides of the pot getting alayer of kadhi sticking to it. This is the sign of the kadhi(curry) almostgetting done. Whilst cooking half the way, you can taste and adjust theseasoning.
