I'm not sure whether these should be called pakoras or bhajias but they're good and simple to make. They're a good late evening snack for a change from ordering pizza. I've only listed onions here but you can try almost any mixture of vegetables.
Sift the gram flour, chilli powder, turmeric, baking powder, and salt into a medium bowl. Add the seeds, onion, green chillies, and coriander and toss it well. Using the end of a wooden spoon, or a chop-stick, gradually mix in enough cold water to produce a thick batter that surrounds all the ingredients. Lumps are not a bad thing.
Heat enough oil in a dutch oven or large work for deep-frying. It goes without saying to be very, very careful here since a wok of hot oil can do some life-long damage. If you like them, keep the kids and pets out of the kitchen. I prefer to use my wok for this but generally opt for the more stable dutch oven. Heat the oil, use a thermometer if you're smart enough to own one, I'm not.
Once the oil's hot, drop in the batter in spoonfuls. Try varying sizes of spoonfuls, I usually fall somewhere between a large walnut and a tennis ball. Fry them until they're golden brown, you'll have to turn them at least once since they float. Drain them well and serve em up.
