In a small pot with lid, bring the quinoa and 1 cup water to boil. Let simmer for approx. 10-15 minutes. Then set aside for at least another 5 minutes before opening the lid.
Peel and chop the onion roughly. Place in the blender with 1/4 cup water and blend to a fine cream. Pour the blended onion into a medium sized bowl.
Add cooked quinoa, buckwheat flour, tahini, smoked paprika, coriander and salt. Stir well.
Dip your hands in cold water prior to forming the patties.
If you have a very good non-stick frying pan, consider frying them without extra oil. Make sure you cook them on a medium low heat for at least 10 minutes on each side.
If you are cooking them in the oven, preheat the oven to 200°C (top-/bottom heat), line the baking tray with parchment paper and cook the patties for approx. 10-15 minutes on each side. Don't overcook, otherwise they might get a little too crunchy.
