It might not feel like it, but MasterChef veteran John Torode has been putting amateur cooks, and some famous faces, through their paces for 13 years on the popular BBC show.

And while you might know him best for his TV partnership with co-host Gregg Wallace, he’s also just published his 11th cookbook.

The chef, 52, hails from Melbourne, Australia, but has been living in the UK for 27 years. His first culinary love, however, comes from much further afield - the street food of the Far East, which, Torode says, “the world is slowly falling in love with”.

His new book, Sydney To Seoul, is a culmination of a lifetime of travels around the east of the continent, his Australian heritage, and stories and conversations with street sellers and local chefs who’ve shared or influenced the recipes he’s featured.

Torode’s exploration into Asian cooking began back in the Nineties - “I discovered a world that is fresh and delicious” - and that discovery has influenced his work ever since, from his restaurant menus to the dishes he and his actress partner, Lisa Faulkner, rustle up at home.

The focus is really on food that grew out of necessity, which ordinary people knock up at home every day in Thailand, or grab from street food stalls in Seoul. “I wanted people to understand it’s not about big things, it’s about lots of little things,” he says. “I find big plates of food scary now.”

From simple Thai classics like fish cakes and som tam (green papaya salad), to karipap pusing (curry puffs) from Malaysia, pajeon (seafood and spring onion pancakes) from South Korea and duck noodle soup from China, the book is a journey of cheap street eats, vibrant curries and fragrant broths.

Like his accent though, Torode’s latest book still has an unmistakable Aussie twang - an entire barbecue chapter and brunches that would be perfectly at home in cafes along Sydney Harbour.

This Australian-Asian mix might seem surprising, but, says Torode: “Australia, and its cuisine was brought about by immigration, with Greeks and Italians arriving in the Fifties, Vietnamese in the Eighties. There’s huge Portuguese influence in Asia; and limes aren’t from South America, they’re from Iran. We talk about fusion of different cultures, but it’s a world of people moving about and talking bits and pieces with them.”

The book also taps into just how much home-cooking has changed in recent years.

“Now, we’re seeing a world where you can get the ingredients,” says Torode. “If I’d put Thai fish cakes in a recipe book 10 years ago, people wouldn’t necessarily cook it - but now it seems everyone has a bottle of chilli sauce in their cupboard, and coriander is in everybody’s fridge, instead of just parsley. Sainsbury’s stock gochujang, fish sauce is on every shelf.

“When I first arrived in the UK, nobody ate squid, nobody ate pork belly. I remember putting it on the menu at Smiths [his first restaurant] in 2000, and someone said, ‘No one will eat pork belly’,” he adds. (And indeed, there’s a recipe for bossam, a Chinese glazed pork belly and sticky sauce dish in the book.)

Other dishes might be more surprising, even now. The Korean army stew, a strange-sounding combination of American hot dogs, spam and processed cheese, with instant noodles, kimchi and gochujang, Torode calls “bonkers” but “fantastic”. It’s fusion at its most fascinating - but again born out of necessity.

“In the war, when there was nothing left in Korea, they used to buy food from the American camps - they had hot dogs and and bologna. But kimchi is eaten with every single meal [in Korea], and there’s noodles because that’s their carbohydrate,” Torode explains. The result was a big pot of hearty stew to feed the family.

These stories are woven into the fabric of the book, and form the backbone to Torode’s dishes. “For me, all the stories are really important, they make me remember the recipe,” he says.

One thing Wallace might not be too impressed by though, is that there are no deserts in sight. “There’s no reason for them,” says Torode, spoken like a true savoury man. “The fact is, the way a lot of food is eaten is that the flavours are sweet and savoury anyway.”

You may have seen the TV duo chiding budding professional chefs for spiceless curries or overcooked fish on MasterChef, but when it comes to home cooks, Torode wants us to worry less about perfection and just experiment more.

“We put enormous amounts of pressure on ourselves, thinking everything we make has to be perfect. There are variables - the coriander is going to taste different depending on where it’s come from, the amount of juice that comes out of a lime... Just in enjoy it. If it doesn’t work the first time, your friends don’t mind, [they] love you - that’s why they bring the white wine and have a nice time.”
