Relaxed, flexible home cooking from Yotam Ottolenghi and his superteam.

Whether they're conjuring up new recipes or cooking for themselves at home, the Ottolenghi Test Kitchen team do what we all do: they raid their kitchens. But then, they turn whatever they find into approachable creations with an 'Ottolenghi' twist.

This instinct is in perfect sync with recent times, when we've all been standing in front of our kitchen shelves, our cupboards and our fridges, wondering what to cook with what we've got; how to put a can of chickpeas or a bag of frozen peas to good use, instead of taking an extra trip to the shops.

For the first time, the team welcome us into their creative space. These dishes pack all the punch and edge we expect from Ottolenghi, but offer more flexibility to make them our own, using what we've got to hand. There's the ultimate guide to creamy dreamy hummus, a one-pan route to confit tandoori chickpeas and a tomato salad that rules them all.

This book is all about feeding ourselves and our families with less stress and less fuss, but with all the 'wow' of an Ottolenghi meal. It's a notebook to scribble on and add to, to take its ethos and absolutely make it your own.

This is how to cook, the OTK way.

Cook, Eat, Repeat is a delicious and delightful combination of recipes intertwined with narrative essays about food, all written in Nigella’s engaging and insightful prose. Whether asking ‘What is a Recipe?’ or declaring ‘Death to the Guilty Pleasure’, Nigella’s wisdom about food and life comes to the fore, with tasty new recipes that readers will want to return to again and again.

‘The recipes I write come from my life, my home’, says Nigella, and in this book she shares the rhythms and rituals of her kitchen through over fifty new recipes that make the most of her favourite ingredients. Dedicated chapters include ‘A is for Anchovy’ (a celebration of the bacon of the sea), ‘Beetroot and Me’, ‘A Vegan Feast’, a shout out for ‘Brown Food’, a very relatable ‘How To Invite People for Dinner Without Hating Them (or Yourself)’, plus new ideas for Christmas.

Within these chapters are recipes for all seasons and tastes: Burnt Onion and Aubergine Dip; Butternut with Chilli, Ginger and Beetroot Yoghurt Sauce; Brown Butter Colcannon; Spaghetti with Chard and Anchovies; Beef Cheeks with Port and Chestnuts; Oxtail Bourguignon; and Wide Noodles with Lamb in Aromatic Broth, to name a few. Those with a sweet tooth will delight in Rhubarb and Custard Trifle; Chocolate Peanut Butter Cake; Rice Pudding Cake; and Cherry and Almond Crumble.

Get ready to welcome friends and family back around your table with Jamie's brand-new cookbook, TOGETHER - a joyous celebration of incredible food to share.

Being with our loved ones has never felt so important, and great food is the perfect excuse to get together. Each chapter features a meal, from seasonal feasts to curry nights, with a simple, achievable menu that can be mostly prepped ahead. Jamie's aim - whether you're following the full meal or choosing just one of the 130 individual recipes - is to minimise your time in the kitchen so you can maximise the time you spend with your guests. Jamie's Together also helps to take the stress out of cooking by arming you with tips, tricks and hacks to stay organised and get ahead of the game.

Inspirational but practical, Together is about comfort, celebration, creating new memories and, above all, sharing fantastic food. This is about memorable meals, made easy. Let's tuck in - together!

Winner of the Observer Food Monthly Cookbook of the Year 2013.

Yotam Ottolenghi and Sami Tamimi are the men behind the bestselling Ottolenghi: The Cookbook. Their chain of restaurants is famous for its innovative flavours, stylish design and superb cooking.

At the heart of Yotam and Sami's food is a shared home city: Jerusalem. Both were born there in the same year, Sami on the Arab east side and Yotam in the Jewish west. Nearly 30 years later they met in London, and discovered they shared a language, a history, and a love of great food.

Jerusalem sets 100 of Yotam and Sami's inspired, accessible recipes within the cultural and religious melting pot of this diverse city. With culinary influences coming from its Muslim, Jewish, Arab, Christian and Armenian communities and with a Mediterranean climate, the range of ingredients and styles is stunning. From recipes for soups (spicy frikkeh soup with meatballs), meat and fish (chicken with caramelized onion and cardamom rice, sea bream with harissa and rose), vegetables and salads (spicy beetroot, leek and walnut salad), pulses and grains (saffron rice with barberries and pistachios), to cakes and desserts (clementine and almond syrup cake), there is something new for everyone to discover.

Packed with beautiful recipes and with gorgeous photography throughout, Jerusalem showcases sumptuous Ottolenghi dishes in a dazzling setting.

Cooking doesn't have to be complicated - that's why Jamie's 5 Ingredients - Quick & Easy Food is sure to become your new best friend in the kitchen.

It's all about making the journey to good food, super-simple. Every recipe uses just five key ingredients, ensuring you can get a plate of food together fast, whether it's finished and on the table super-quickly, or after minimal hands-on prep, you've let the oven do the hard work for you. We're talking quality over quantity, a little diligence on the cooking front, and in return massive flavour. Each recipe has been tried and tested (and tested again!) to ensure the book is packed with no-fuss, budget-friendly dishes that you can rustle up, any day of the week.

With over 130 recipes, and chapters on Chicken, Beef, Pork, Lamb, Fish, Eggs, Veg, Salads, Pasta, Rice & Noodles and Sweet Things, there's plenty of quick and easy recipe inspiration to choose from. Think Roast tikka chicken - a whole bird rubbed with curry paste and roasted over golden potatoes and tender cauliflower, finished with fresh coriander. Or, Crazy simple fish pie - flaky smoked haddock, spring onions, spinach and melty Cheddar, all topped off with crisp, golden filo, and ready to tuck into in less than 30 minutes. With every recipe you'll find a visual ingredient guide, serving size, timings, a short, easy-to-follow method, and quick-reference nutritional information.

This is Jamie's easiest-to-use book yet, and the perfect cookbook for busy people.

'Ottolenghi changed the way we cook in this country just as surely and enduringly as Elizabeth David’s A Book of Mediterranean Food had in 1950. It brought into our kitchens bold flavours, a vivid simplicity, a spirited but never tricksy inventiveness and, above all, light.’ Nigella Lawson

Inspired by their childhoods in West and East Jerusalem, Yotam Ottolenghi’s and Sami Tamimi’s original cookbook Ottolenghi: The Cookbook showcases fresh, honest, bold cooking and has become a culinary classic.

Yotam and Sami's inventive yet simple dishes rest on numerous culinary traditions, ranging from North Africa to Lebanon, Italy and California. First published in 2008, this new updated edition revisits the 140 original recipes covering everything from accomplished meat and fish main courses, through to healthy and quick salads and suppers, plus Ottolenghi's famously delectable cakes and breads.

A new introduction sheds fresh light on a book that has become a national favourite.

Ottolenghi is an award-winning chef, being awarded with the James Beard Award 'Cooking from a Professional Point of View' for Nopi in 2016, and 'International Cookbook' for Jerusalem in 2013. In 2013 he also won four other awards for Jerusalem.

Vegetables have moved from the side dish to the main plate, grains celebrated with colour and flair. It’s a revolution that is bold, inspiring and ever-expanding.

Yotam Ottolenghi's Plenty changed the way people cook and eat. Its focus on vegetable dishes, with the emphasis on flavour, original spicing and freshness of ingredients, caused a revolution not just in this country, but the world over.

Plenty More picks up where Plenty left off, with 150 more dazzling vegetable-based dishes, this time organised by cooking method. Grilled, baked, simmered, cracked, braised or raw, the range of recipe ideas is stunning. With recipes including Alphonso mango and curried chickpea salad, Membrillo and stilton quiche, Buttermilk-crusted okra, Lentils, radicchio and walnuts with manuka honey, Seaweed, ginger and carrot salad, and even desserts such as Baked rhubarb with sweet labneh and Quince poached in pomegranate juice, this is the cookbook that everyone has been waiting for.

Following the record-breaking success of 30-Minute Meals, Britain's most-popular cookbook of all time, Jamie Oliver brings us the even-better 15-Minute Meals.

This book is completely devoted to what we are asking for - super quick, tasty, nutritious food that you can eat everyday of the week. In creating these recipes Jamie's made sure they're methodical, clever, sociable, fun, with beautiful food full of big flavours. It's a classic book that will arm you with the skills to create wonderful meals, shockingly fast.

He's taken inspiration from all over the world, embracing the tastes that we all love, playing on classic chicken, steak and pasta dishes, looking at Asian-inspired street food and brilliant Moroccan flavours, putting together great salads and so much more. And these are some of the quickest and easiest meals Jamie's ever done.

These recipes have been tested and tested to ensure that this book is a reliable companion for you and your family.
