Place all the dry batter ingredients in a bowl and whisk together

Lightly sprinkle fish with an additional few tablespoons of flour. This is to help the batter stick

Pour most of the cold beer into the dry ingredients and whisk to combine, add the remaining beer until you get a milkshake/thin smoothie consistency. This isn't a heavy batter

Heat a small saucepan of oil over a medium heat. Test the oil buy dropping a drop of batter into the oil, if it sizzles you're good to go. Dip the fish into the batter and place into the oil and fry

Fry for 3-4 minutes or until golden brown (time depending on the thickness of your fish)

Drain the crispy fish on a paper towel and season with additional Man Grind

To assemble your burger warm the burgers buns in the oven and spread tartare sauce on each side of the bun. Layer your chosen fillings and top with the fish and top of the bun. Serve immediately
