I tried the recipe above (the one I scanned) on some frozen tilapia fillet (fresh fish other than salmon is very expensive and hard to find in Stockholm, and this was just a test). The fish was thawed and room tempered, then patted dry with paper. Brushed with a mix of lemon juice, worcestershire sauce and dijon mustard. Marinated for 20 minutes while preparing the batter. The fish was dusted with rice flour, dipped in the batter and deep-fried. The temperature when I put in the fillet was 180-190 C (345-355 F), but since my deep-frier is small (3.5 litres/1 US gallon of oil), it probably dropped to 160-170 C (320-338 F) before rising again.
Observations:
* SR flour isn't sold in Sweden. I added one tsp bicarbonate instead.
* One tbsp sugar in the batter seems much. It's probably there to give the batter a browner colour, but it made the result burnt. It wasn't possible to fry the fish for the prescribed time since the batter was starting to burn immediately. I think the sugar can be excluded altogether.
* The lemon/worcester/mustard seasoning was delicious.
* The coating turned out crisp on the outside but a little soggy near the fish.
* Three minutes of deep-frying made the fish perfectly cooked.
* The batter was difficult to handle. It stuck to the fingers and the deep-fryer basket and the fish had to be prised loose from the basket.
But an overall impression was much better than I expected. The quest for the perfect FnC has just begun...
More input and suggestions are highly appreciated. Thank you.
