The batter: In a bowl mix flour, pepper, coriander, paprika, cumin or the spices you prefer, and salt. Add ice water or cold beer. The batter should not be too liquid. Heat up the pan or fryer you will be using and add oil.
The fish: Rinse and pat the cod dry. Cut in squares or rectangles. Dip into the batter and fry on both sides. Drain on paper towel or paper.
You can use halibut or acadian redfish as well.
