Cut fish into short strips, 1-2 inch thickness, add salt & pepper set aside. Heat oil for frying.
In a bowl combine flour, salt, dry spices & green chilly. Slowly add 1/2 beer bottle at a time & whisk. If batter is too thick add more beer, if runny add flour. Should be able to coat fish well.
Add fish to batter, allowing it to marinade for 10 mins. Begin frying for 2-3 mins and flip. Fry until golden brown.
Voila! Wrap in parchment for presentation, serve with lime wedge! Sprinkle with salt depending on taste! Let me know if it's successful.
