I know this is an old thread but I've just seen it and thought I'd add the falafel recipe I always use - I love it:
250g dried chickpeas, soaked overnight, cooked and cooled
3 garlic cloves, crushed
1/2 onion, grated
1 large bunch coriander, finely chopped
1 large bunch parsley, finely chopped
1 egg
1/4 tsp bicarb
50g plain flour
1 1/2tsp cumin
1 1/2tsp coriander
1tsp turmeric
Zest of 1/2 lemon
Salt and pepper
2tbsp sesame seeds
2tbsp nigella/black onion seeds
Pulse the chickpeas in the food processor until it is a fairly smooth paste but has some whole chickpeas in it. Add the garlic, onion, spices, herbs, bicarb and lemon zest and mix together. Shape into golf ball sized balls and then flatten slightly to make patties. Mix the sesame and nigella seeds together and dip the falafel into them, pressing down if necessary to coat the patties. Place on a greased baking tray and cook at 180c for 25-30 mins, turning halfway through, until golden and cooked through.
Really good with a cumin and mint yoghurt in toasted pittas. So good!!!
