Ingredients

Scale

Fish Fingers

250g sustainable white fish fillets (cod, haddock, or pollack)
2 tbsp plain flour
1 egg, beaten
4 tbsp dried breadcrumbs (panko recommended)
2 tbsp sesame seeds
Vegetable oil, for frying

Lime Mayo & Toppings

1 ripe avocado
Juice of 1 lime
Small pack coriander, chopped
2 tbsp light mayonnaise
2 burger buns, split and toasted

Instructions

Prepare the Fish Fingers: Cut the fish fillets into 4 chunky fingers. Season the plain flour with a little salt and pepper and place it in a bowl. Beat the egg in a separate bowl. Combine the breadcrumbs and sesame seeds in a third bowl.
Coat the Fish: Dust each fish finger in the seasoned flour, making sure they are fully coated. Then dip them into the beaten egg, and finally roll them thoroughly in the breadcrumb and sesame seed mixture. For best results, chill the coated fish fingers in the refrigerator for 10 minutes to help the coating set.
Fry the Fish Fingers: Heat a drizzle of vegetable oil in a frying pan over medium heat. Fry the fish fingers for 3 to 4 minutes on each side until they are golden brown and cooked through. Add more oil if the pan looks dry to ensure even cooking and crispiness.
Prepare the Avocado and Lime Mayo: While the fish cooks, peel, stone, and slice the avocado. Immediately squeeze some lime juice over the avocado slices to prevent browning. In a small bowl, mix the remaining lime juice and chopped coriander into the light mayonnaise.
Assemble the Burgers: Spread a little of the lime coriander mayo over the bottom halves of the toasted burger buns. Top each with two crispy fish fingers, a few slices of avocado, and then the bun tops. Serve any remaining lime mayo on the side for extra flavor.

Notes

Use sustainable white fish options to ensure environmentally friendly choices.
Chilling the breaded fish before frying helps the coating adhere better and results in crispier fish fingers.
Panko breadcrumbs provide a lighter, crispier texture compared to traditional breadcrumbs.
You can customize the burger by adding lettuce, tomato slices, or pickles for extra crunch and flavor.
For a healthier version, consider baking the fish fingers in a preheated oven at 200°C (400°F) for about 15-20 minutes, turning halfway through, instead of frying.
