Keep it in the fridge, covered, if you’re making this in advance. Step Cut 1kg white fish fillets with the skin removed into fish-finger sized pieces, rubbing your hand over the surface to check for any little bones that might still be there. Season each piece. Step Put the 2 large lightly beaten eggs, 100g plain flour seasoned with salt and pepper, and 250g white breadcrumbs separately on three plates. Dip each piece of fish in the flour, then the egg, then the breadcrumbs. Set them on a baking sheet as you go, ready to cook. Step Heat some oil in a frying pan over a medium heat until a breadcrumb sizzles and turns golden-brown when dropped into it. Put the fish fingers into the pan, in batches if you have to, and fry for 2-3 minutes on each side, or until they are crispy, golden and cooked through. Remove them as they are cooked with a slotted spoon and transfer to a double layer of kitchen paper. Blot the excess oil. Step Lightly butter slices of bread – enough for six sandwiches – and spread on some of the mayo. Add the baby gem and fish fingers, and slice each person’s sandwich in half to serve.
