A Masterclass in Japanese Cooking With Jun Tanaka

The average home cook is frightened of Japanese food. Eating it, yes. Pulling up a stool in front of a slow moving whirlpool of conveyor belt sushi or perching next to the open inferno of a Teppanyaki joint while the chef expertly flicks rice towards the ceiling and makes a squid ring volcano explode, yes, of course. But actually cooking the stuff?

The average home cook is frightened of Japanese food.

Eating it, yes. Pulling up a stool in front of a slow moving whirlpool of conveyor belt sushi or perching next to the open inferno of a Teppanyaki joint while the chef expertly flicks rice towards the ceiling and makes a squid ring volcano explode, yes, of course. But actually cooking the stuff? That's where most people leave it to the chefs wielding the meat cleavers, bamboo rolling mats and chopsticks.

It isn't too difficult to see how Japanese food got its complicated label and it seems to go deeper than just the feng shui balancing act of flavours in the cuisine. Every tourist in Japan will notice that the traditional restaurants aren't particularly big on variety. In fact, you're far more likely to find Michelin-starred restaurants that specialise in one singular dish - like udon noodles or tempura vegetables - where the chefs work to elevate that dish to ultimate levels of exquisite faultlessness that you simply wouldn't get in a multi-focus establishment. There are London equivalents, like Tramshed with chicken or Hawksmoor and steak, but never to the same degree of narrow, immaculate focus.

This lack of single focus restaurants puzzles Jun Tanaka, an American-born, British Japanese chef who has featured on just about every cooking television programme going and who, despite starting his career as an apprentice under the incomparable Roux Brothers at Le Gavroche, has stayed firmly anchored to his Japanese food roots.

At a Sainsbury's master class last week, in between dropping shitake mushrooms into sizzling oil and chopping scarlet chillies in a blur of Japanese steel, Tanaka half confirmed the opening of his latest venture, a French, Mediterranean restaurant in London this year.

As the acrid smell of fish sauce slowly filled the room like a rotten mushroom cloud, I was transported back to Tokyo and the cavernous warehouse of the Tsukiji Fish Market. I could practically feel the wet, icy slosh of fishy water as it soaked through my impractical ballet pumps, hear the greasy roar of the chainsaws as they sliced through the silvery, Moby Dick-sized torsos of giant tuna and feel the frigid air against my skin. Everywhere you looked in the market there was a crate of something familiar next to something unrecognisably bizarre: mussels as big as my forearm, burnished octopus tentacles knotted around fat white scallops, spikey urchins, pots of what can only be described as gloop and tiny brown shells filled with something unidentifiable.

A limited number of tourists are admitted in the early morning to the hallowed inner hall of fish auctions - where you can gape at fish heads the size of dogs and watch giant haunches of tuna go for eye-watering amounts of Yen - before being turfed back into the melee of hagglers and fisherman and left ducking and diving amid the flying ice, speeding trucks and dungaree-clad, machete-waving workers.

Outside the warehouse there's the jōgai-shijō outer marker, a mix of shops and eateries selling kitchen tools, restaurant supplies and, of course, the world's freshest, simplest and most delicious sushi and seafood, and that was exactly what came to mind when I sampled Tanaka's bowls of spicy, sour sea bass soup, umami lamb and buttery fleshed salmon with delicately pickled cucumber.

Alongside his obvious French flavours, Tanaka grew up on a diet of simple Japanese cooking and firmly believes that, with the right ingredients and some very fresh fish, anyone can cook up a Japanese feast in minutes.

Tanaka's Top Tips

  • Don't use a whisk when making tempura batter as the overworking makes the flour become glutinous, resulting in a heavy batter. Use chopsticks instead and remember that lumps are ok.
  • Try using lager like Japanese Asahi in your batter instead of sparkling water for a fuller flavour and super crispy crust.
  • Add umami, the fifth flavour, to dishes like beef stew with a few slices of anchovy.
  • The next time you make mayonnaise, substitute the Dijon mustard for a blob of wasabi paste for a peppery, spicy flavour.
  • Swap mustard for tamarind paste in your salad dressings for a sharp, sour and fruity note or use it to marinade meats as it's a natural tenderiser.

Tanaka shared some quick, easy, healthy recipes that took him about ten minutes to knock up, making them perfect for speedy suppers or to pull out at a last minute dinner party. All recipes serve four people comfortably.
