How We Met: Raymond Blanc & Agnar Sverrisson

Raymond Blanc, 60, opened Les Quat'Saisons, his first restaurant, in Oxford in 1977. Seven years later, he opened the country-house hotel and restaurant Le Manoir aux Quat'Saisons, which has had two Michelin stars for 19 years. He lives in Oxfordshire

Aggi arrived at Le Manoir as chef de partie in 2001, not cocky, but a very confident cook, and I noticed immediately that the team liked him. He has a generous personality and he can be one of the team as well as a leader – what he cares about is the final achievement.

Aggi rose quickly, which is tough in a kitchen of 42, but he is a perfectionist and I love people who are driven by a sense of things never being good enough. Once you say it is good enough, you are out of the game. He was always probing, always asking questions.

Even back then, he had his own identity. Chefs today travel so much, they have many more influences than they did before. There's nothing wrong with that, but it can result in confusion for the chef, and then for the people he is cooking for.

What I like about Aggi is that while embracing different cultures, he keeps his own Icelandic identity precious. There's no doubt that he loves fish, and Texture, the restaurant he now owns, is to fish what St John is to offal – all those different ways of preparing, marinating, presenting it.

Although I knew he was a brilliant cook, I was fearful about whether he could translate it into areas where he was untested: design; business. But everything has worked out perfectly. Few businesses have what Aggi and his sommelier Xavier have when they start – most chefs' first kitchen is a rat-hole, and here they are at the best address in London. They have been lucky, but hard work creates luck.

My greatest pleasure is to see young people who have worked with me in their own restaurants. Coming to Texture is like my second home; I can turn up at any time, be welcomed with a "Hello, Chef," and we'll sit down and share some fish and wine.

Aggi worked a lot with my executive chef Gary Jones, and we agreed that the only bad thing about him was that he swears like a trooper. A kitchen should be a serene place. I think it was a lack of confidence. I've lost it myself in the past, so I understand that that kind of behaviour comes from frustration, but to be a great chef you need to manage yourself as well as others. I've learnt that, and I think he has too.

Agnar Sverrisson, 35, trained in his native Iceland, before working at Gordon Ramsay's Pétrus. He became head chef at Le Manoir aux Quat'Saisons before setting up the Michelin-starred Texture in 2007 with Le Manoir's head sommelier, Xavier Rousset. He lives in west London

Everyone wants to work for Raymond. You look at the number of Michelin-starred chefs he has trained and you don't need to say any more. I met him just after I was hired by Gary, the executive chef at Le Manoir. Obviously, Raymond is a big, big, chef so I was nervous as fuck. I thought it would be a two-minute hello, but he was extremely friendly and chatted to me for a long time about my past, my dreams.

What I love about his food is the freshness, the cleanness, the seasonality. When I arrived at Le Manoir, all I knew was reduced, heavy sauces, gluey food. I didn't know anything about seasonal food – and I had been working at very good restaurants in London. I don't think people understand how ahead of his time Raymond was. He was doing things 20 years ago that chefs are only now discovering.

Working at Le Manoir was tough. I stayed for five years, but for the first two I said to myself every other day, "I think I'm going to leave soon." Those first years were very difficult simply because there was so much to learn. Everyone is nervous when Raymond is around and, to begin with, I was scared whenever he came to taste anything. It was always, "This isn't good, that's not good." But slowly you start to know what he is looking for.

First and foremost, what I learnt from Raymond is that it's all about flavours. He has the best palate I have known and he taught me how you can train your own palate. He loves blind tastings, so he will take 10 or 15 glasses with different mixtures of water and salt, for example, and you have to pick out which is the right level of saltiness that you want in a dish.

I remember going with him to Chicago to cook once and I got sick and had to go to hospital. That really showed me who he was as a person, because he spent two days at the hospital with me. He even had a 10-course dinner sent to me in my hospital room from the best restaurant in the city.

When Gary offered me a head chef position after two-and-a-half years, I wanted to leave, because my dream has always been to open my own restaurant, but I knew it would open so many doors.

I kept working on my plans for Texture, though, and Raymond was very supportive at every stage – I must have taken the business plan to him to look at 1,000 times. Every time he told me to change it slightly.

When Raymond came to the restaurant for the first time I was very proud and confident that he would like it. What made me proudest, though, was that he seemed to be proud of me.

Raymond Blanc and Gary Jones will be cooking at Agnar Sverrisson's Texture, (34 Portman Street, London W1, 020 7224 0028, texture-restaurant.co.uk), in September
