Put butter on top of the fish and then place the slice of lemon on top of the butter.

Close the foil well and then cook in the air-fryer at 180 degrees Celsius for 15 minute and leave in the air-fryer for 5 minutes. Cooking time depends on the thickness of the fish. This piece was fairly thick. Add sufficient lemon juice or it dries out. Keep the foil sealed for 5 minutes so that any moisture can be absorbed

Goes well with the cucumber raita
