Step 1: Prepare the Falafel Mixture
1. Drain the soaked fava beans and rinse them well.
2. In a food processor, add the fava beans, onion, garlic, parsley, cilantro, dill, coriander, cumin, baking soda, salt, black pepper, and cayenne pepper (if using).
3. Blend the mixture until it forms a smooth, thick paste, scraping down the sides as needed. If the mixture is too dry, add a tablespoon of water to help it blend.
4. Transfer the mixture to a bowl, cover, and let it rest in the fridge for 30 minutes to firm up.
