Place all ingredients except oil into a mini food processor and blend adding oil gradually until it thickens
Slaw
Place all chopped ingredients into a bowl and mix together
Batter
Place ingredients into a bowl and whisk together. If batter is too thick add more sparkling water. If too thin add a little more flour
Fried Fish Sandwich
Heat oil to about 190c. Season fish and dust in flour.
Dip fish into batter, lifting it so that excess batter falls away. Place gently in heated oil away from you so that the oil doesn't splatter you. Cook until fish is crispy - about 4/5 minutes. Lay in a wire rack, season and allow to rest for a minute.
Sandwich Assembly
I like to toast my bun a little so it doesn't get all soggy. Place a little aioli on base of bun, add fish, then slaw and drizzle aioli over. Top with bun and DESTROY!!

Tips/Tricks
you can use mayo instead of making aioli if preferred and add the coriander to the slaw and place the pickled jalapenos or chopped jalapenos within the sandwich to cut out a few steps
don't forget to season the fish before and after frying
you can also substitute frozen battered fish if in a hurry but using fresh fish where possible is always best
