After winning rave reviews for their latest cookbook Jerusalem, restaurateurs Yotam Ottolenghi and Sami Tamimi share the delicious side of their diverse city and discuss what makes their 'sunny food' so special.

By Diana Pilkington

It's hard to walk past an Ottolenghi shop front without nipping in for a giant meringue or a closer look at the salad displays, which burst with colour, freshness and vitality.

With their shops, cookbooks and magazine columns, Yotam Ottolenghi and Sami Tamimi have captured the imagination of foodies everywhere with their particular brand of 'sunny' cuisine, and made exotic ingredients like sumac that bit more familiar.

"Our food is popular because it's very colourful and bold food, and it's in big quantities," says Tamimi, the company's head chef. "It's really to do with where we came from. You go into the markets and the food is always piled high, so we've unconsciously tried to recreate that."

Indeed, after the runaway success of their first two cookbooks (Ottolenghi: The Cookbook and Plenty), they've gone back to their roots with their third and most personal offering. Jerusalem delves into the food of their home city, a melting pot of diverse flavours and cultures.

The result is a book that's brimming with recipe ideas, mouth-watering photography and snippets of history - not to mention a fair amount of Swiss chard.

"People don't eat it enough here. It's a wonderful product," Tamimi says of the vegetable.

"It's so easy to grow and it's a beautifully flavoured thing - a bit tangy, a bit sweet and good for you."

The pair met in the late Nineties while working at Baker And Spice bakery and have since built up a successful partnership.

But, despite their shared history, their different ethnic backgrounds (Ottolenghi is from the Jewish west and Tamimi from the Arab east of Jerusalem) mean they would have struggled with a working relationship back home.

"I don't think there are many businesses in Israel that are co-owned by Jews and Arabs," says Ottolenghi.

"It's really sad because there's no reason why it wouldn't work, but I have a feeling that it wouldn't have stood the test of time because there's just too much suspicion and negativity in the air.

"Every time there's some tension in the West Bank, everything becomes a bit awkward. Here, we just live our lives and do our thing and there's some sense of normality."

Their 'thing' is quite varied these days. Tamimi keeps a close eye on their eateries (they have four shops and a restaurant, Nopi, in London) while Ottolenghi will soon become a more familiar face to TV viewers thanks to a More 4 series exploring the food of Marrakech, Tunis, Tel Aviv and Istanbul.

"So I'll be one of those chefs," he says, laughing, referring to the many names who have moved from the kitchen to the screen. "If the project is interesting I'll do it and if it's not I won't. It's not really about fame - but I guess everybody says that!"

The pair admit it took some time to get used to British weather, but now feel at home here and can't imagine moving back to Jerusalem any time soon. However, they still cling to the faint hope that food can unite their fractured native city.

"The restaurants and markets are some of the only places where you see Jews and Arabs mix," Ottolenghi says.

"If there was some glimmer of hope, food would be it. But unfortunately at the moment it's quite bad so it just doesn't feel like peace in the Middle East is the next thing.

"If everyone could appreciate the healing power of food as much as we do then I think it would have had a chance."

Stuffed aubergine with lamb and pine nuts

(Serves 4)

4 medium aubergines (about 1.2kg), halved lengthways

6tbsp olive oil

1tsp ground cumin

1½tbsp sweet paprika

1½tbsp ground cinnamon

2 medium onions (340g in total), finely chopped

500g minced lamb

50g pine nuts

20g flat-leaf parsley, chopped

2tsp tomato puree

3tsp caster sugar

150ml water

1½tbsp lemon juice

1tsp tamarind paste

4 cinnamon sticks

Salt and black pepper

Preheat the oven to 220C/200C Fan/Gas Mark 7.

Place the aubergine halves, skin-side down, in a roasting tin large enough to accommodate them snugly. Brush the flesh with 4 tablespoons of the olive oil and season with 1 teaspoon of salt and plenty of black pepper. Roast for about 20 minutes, until golden brown. Remove from the oven and allow to cool slightly.

While the aubergines are cooking, you can start making the stuffing by heating up the remaining olive oil in a large frying pan.

Mix together the cumin, paprika and ground cinnamon and add half of this spice mix to the pan, along with the onion. Cook on a medium-high heat for about 8 minutes, stirring often, before adding the lamb, pine nuts, parsley, tomato puree, 1 teaspoon of the sugar, 1 teaspoon of salt and some black pepper. Continue to cook and stir for another 8 minutes, until the meat is cooked.

Place the remaining spice mix in a bowl and add the water, lemon juice, tamarind, remaining sugar, cinnamon sticks and ½ teaspoon of salt; mix well.

Reduce the oven temperature to 195C/175C Fan/Gas Mark 5½.

Pour the spice mix into the bottom of the aubergine roasting tin. Spoon the lamb mixture on top of each aubergine. Cover the tin tightly with foil, return to the oven and roast for 1 hour 30 minutes, by which point the aubergines should be completely soft and the sauce thick; twice through the cooking, remove the foil and baste the aubergines with the sauce, adding some water if the sauce dries out. Serve warm, not hot, or at room temperature.

Roasted chicken with Jerusalem artichoke and lemon

(Serves 4)

450g Jerusalem artichokes, peeled and cut into six lengthways (1.5cm thick wedges)

3tbsp lemon juice

8 chicken thighs, on the bone with the skin on, or a medium whole chicken, divided into four

12 banana shallots, peeled and halved lengthways

12 large garlic cloves, sliced

1 medium lemon, cut in half lengthways and then into very thin slices

1tsp saffron threads

50ml olive oil

150ml cold water

1½tbsp pink peppercorns, slightly crushed

10g fresh thyme leaves

40g tarragon leaves, chopped

2tsp salt

½tsp black pepper

Put the Jerusalem artichokes in a medium saucepan, cover with plenty of water and add half the lemon juice. Bring to the boil, reduce the heat and simmer for 10-20 minutes, until tender but not soft. Drain and leave to cool.

Place the Jerusalem artichokes and all the remaining ingredients, excluding the remaining lemon juice and half of the tarragon, in a large mixing bowl and use your hands to mix everything together well. Cover and leave to marinate in the fridge overnight, or for at least 2 hours.

Preheat the oven to 240C/220C Fan/Gas Mark 9.

Arrange the chicken pieces, skin-side up, in the centre of a roasting tin and spread the remaining ingredients around the chicken. Roast for 30 minutes. Cover the tin with foil and cook for a further 15 minutes.

At this point, the chicken should be completely cooked. Remove from the oven and add the reserved tarragon and lemon juice. Stir well, taste and add more salt if needed. Serve at once.

Roasted sweet potatoes and fresh figs

(serves 4)

4 small sweet potatoes (1kg in total)

5tbsp olive oil

40ml balsamic vinegar (you can use a commercial rather than a premium aged grade)

20g caster sugar

12 spring onions, halved lengthways and cut into 4cm segments

1 red chilli, thinly sliced

6 fresh and ripe figs (240g in total), quartered

150g soft goat's cheese, crumbled (optional)

Maldon sea salt and black pepper

Preheat the oven to 240C/220C Fan/Gas Mark 9.

Wash the sweet potatoes, halve them lengthways and then cut each again similarly into 3 long wedges. Mix with 3 tablespoons of the olive oil, 2 teaspoons of salt and some black pepper. Spread the wedges out on a baking sheet, skin-side down, and cook for about 25 minutes until soft but not mushy. Remove from the oven and leave to cool down.

To make a balsamic reduction, place the balsamic vinegar and sugar in a small saucepan. Bring to a boil then reduce the heat and simmer for 2-4 minutes, or until it thickens. Be sure to remove the pan from the heat when the vinegar is still runnier than honey; it will continue to thicken as it cools. Stir in a drop of water before serving if it does become too thick to drizzle.

Arrange the sweet potatoes on a serving platter. Heat the remaining oil in a medium saucepan and add the spring onions and chilli. Fry on a medium heat for 4-5 minutes, stirring often, making sure not to burn the chilli, and then spoon the oil, onions and chilli over the sweet potatoes. Dot the figs among the wedges and then drizzle over the balsamic reduction. Serve at room temperature with the cheese crumbled over, if using.
