Cod Fillet Tendon.

Updated: Sep 30, 2021

Here's a recipe that you could call, with just a little stretch of the imagination, "Japanese fish and Chips". You get a fillet of cod fried in tempura batter served on a bed of the staple Japanese food - steamed rice.

Of course, it wouldn't be a Japanese meal without some vegetables and here you get slices of sweet potato, carrot and rocket - these were my choices from the larder - you could use other combinations that take your fancy. No salt' n 'vinegar flavourings here though - tendon dishes are served with a tendon sauce - a combination of soy sauce and mirin. All in all, this makes a great one-dish recipe for lunch or dinner.

You can make your own tempura flour or you can buy a ready made - I used showa brand tempura flour which is a mix of wheat flour, egg yolk powder, pumpkin powder and baking powder - it gives a nice, light result. Rather than coating everything in tempura batter first, this is a recipe where you coat each item separately with batter and deep fry, then coat the next item. The sweet potato takes the longest time - 2-3 mins - you can test whether the slices are done with a chopstick or skewer - the carrot matchsticks and the rocket are formed into little bundles in the batter and then plunged into the oil to stick them together - they take no time at all. I fried the cod fillets for about 2 - 3 mins and kept an eye on the colour to make sure the batter didn't overcook.

The rest is simple - arrange the tempura on a bowl of fresh rice and drizzle over the ten-don sauce - and you have a tasty, satisfying main meal to serve.
