Sourdough Battered Fish

Ingredients
1 fillet of fish per person and rubbed with a small amount of white flour (this helps the batter to stick).

For the Batter  (will make enough for 6 fillets of fish)
1/2 cup white spelt flour
1/2 cup sourdough starter
1/4 cup water
1 teaspoon baking soda
1/3 cup something fizzy (either beer, kombucha, kefir, soda water)
1 Tablespoon lemon pepper (optional)
1/2 teaspoon salt
coconut oil for frying

Combine the first 3 ingredients in a bowl big enough to dip fish into. Leave until ready to cook the fish.
When ready to cook the fish, add everything else except the coconut oil, and mix well.
Heat some coconut oil in a fry pan (about 3 Tablespoons) and ensure it's hot before beginning to cook. You can drop just a spot of batter in to check. It should sizzle, bubble, and brown quite quickly.
If it isn't hot enough the batter will stick to the pan.
When hot enough, dip the fish into the batter and place into the hot oil. Let cook until browned on the first side then flip over and brown the second side.
Serve immediately and enjoy.
