Step 4
Pulse Swiss chard, parsley, cilantro, and dill together in a food processor, working in batches, until finely chopped but not mushy. Place into a large bowl with barberries, walnuts, garlic, salt, fenugreek, tarragon, turmeric, cinnamon, saffron, rose petals, and black pepper. Stir to combine. Add 6 eggs and mix well to combine; the batter should have the consistency of thick yogurt or soft serve ice cream. If it doesn't, add more eggs, 1 at a time, and mix to combine.
