The Rational SelfCooking Center gives us the consistent quality we need, every time. You don't get that from any other oven – no combi steamer, conventional oven or baking oven can match it

Custard tart may not be the first food one associates with two Michelin stars. But since Marcus Wareing prepared it on the Great British Menu, to celebrate the Queen's 80th birthday, it has become a signature dish at his eponymous restaurant at The Berkeley in Knightsbridge. So much so that people come specifically to taste the famous creation. Which means it has to be perfect, every time. And according to the master chef, the only way to achieve a custard tart with the quality that two Michelin stars demand is to bake it in a Rational SelfCooking Center.

"The Rational SelfCooking Center gives us the consistent quality we need, every time. You don't get that from any other oven – no combi steamer, conventional oven or baking oven can match it," he says.

The Rational at The Berkeley is used for all of the restaurant's pastry items (including the custard tart) plus other hot kitchen preparations (such as rhubarb and olive oil muffins served with foie gras) as well as for a variety of other tasks, steaming vegetables for soups and purees for example. It's also used for overnight cooking, including drying out vegetable and fruit crisps – another process that requires precision control.

"For years we've had an older Rational, a ClimaPlus Combi, and it still gives great service. But the new SelfCooking Center is even better, a real improvement. Results are superior and more consistent," says Wareing.

Before Wareing installed his new Rational he attended a TeamCooking Live demonstration to see the latest models in action. "The Rational chefs showed me what the SelfCooking Center can do and, frankly, I was gobsmacked," he admits. "The potential is huge, for all sorts of cooking."

"Another big plus with Rational is the support that we get, after the sale, both from the company and its chefs," adds Wareing. "If there are any issues, they are here to sort them right away, there's no waiting."    

The Rational is simple to operate and it's also very quiet, which is a big plus in the busy kitchen. Plus, the new CareControl feature means there no need for a water filter – a vital space saver in any kitchen where space is limited.

"We switch it on at 7am and turn it off at 1am – unless we're using it to cook overnight," says Wareing. "So it has to be ultra reliable. And after anything up to 17 hours in the kitchen, the last thing any member of staff wants to do is scrub the oven, so the fact that the Rational cleans itself is a huge bonus.

"It's invaluable. We wouldn't use any other combi steamer."
