In a medium-size mixing bowl, combine the flour mixture ingredients and set aside.
Clean, wash, and dry cilantro and mint leaves and place in a mini food processor. Puree to a fragrant green paste and set aside.
Sauté finely chopped onion in grape seed oil or your preferred oil.
Add ground cumin and cinnamon and let simmer.
Add coriander and mint paste.
Add vegetable broth and lemon juice.
Let simmer and reduce to thicken sauce.
Add salt to taste.
Slice snakehead fillets into workable 2 to 3 inch pieces. Rinse and pat dry.
Transfer snakehead to the flour bowl. Dredge the fish into the flour mixture and dust off extra coating.
Deep fry by adding enough oil to a frying pan or wok to cover the fish pieces, at least 1 inch deep. I prefer to fry in peanut oil.
Heat oil to 375 degrees. Carefully set prepared fish in the oil and fry until light golden-brown.
Drain on a clean towel or paper towel.
Plate with cilantro and mint sauce. Add fresh cilantro garnish. Serve hot.
