Continental bakery and patisserie Jungs is to open a glass-walled craft bakery, allowing high-street shoppers to watch the bakers at work almost 24 hours a day.

The extension to the shop and café in Beaconsfield is due to open after Easter, at a cost of around £400,000. It will showcase the work of 12 bakers and patissiers, including the newly appointed Simon Jenkins - Gordon Ramsay’s former executive pastry chef - who will make gateaux, chocolate work and sugar sculptures to order.

Owner Richard Mathea said the business needed more space, so they had decided to expand into the next-door restaurant and put everything on show. "The demonstration kitchen will be behind a glass wall, behind the retail shop, where people will be able to watch our staff, and there will be another glass wall where they can see the bakery."

Customers will also be able to take lessons in the demonstration kitchen.
