Place the dried fava beans in a large bowl and cover with plenty of water. Soak for at least 8 hours or overnight, then drain and rinse well.

In a food processor, combine the soaked beans, onion, garlic, dill, and cilantro. Pulse until the mixture is finely ground and holds together, scraping down the sides as needed. Do not turn it into a puree; it should have some texture.

Transfer the mixture to a bowl. Stir in the salt, cumin, coriander, and baking powder until well combined.

Heat about 2 inches of vegetable oil in a deep pan or pot to 350°F (175°C).

Take small portions of the dough (about 2 tablespoons) and form them into balls, then flatten them slightly into discs.

Carefully drop the patties into the hot oil, frying in batches to avoid overcrowding. Fry for 3-4 minutes per side until deep golden brown and crispy.

Remove with a slotted spoon and drain on paper towels. Serve warm with pita bread or tahini sauce.
