The bakery is the first production facility to be owned and operated by the 16-year-old company, which, until now, has produced all of its 200-strong portfolio in partnership with other UK manufacturers.
Ten organic pastry products will be produced at the bakery, including traditional hand-crimped Cornish and cheese and onion pasties; miniature lemon curd and strawberry, blackcurrant and raspberry jam tarts and cheese or bacon savoury flans, as well as larger lemon, chocolate, treacle and Bakewell tarts.
All have been developed by William Curley, previously chief patissier at The Savoy, and will be sold in Waitrose stores at rsps ranging from £2.49 to £3.99.
Managing director Belinda Gooding said est-ablishing the company's first production facility in Cornwall was an "incredibly exciting milestone" for the brand. "The region has a very strong affinity with Duchy Originals and it was important for us to base the bakery there," she added.
Duchy Originals Foods Limited is aiming to source as many local organic ingredients as possible. All meat for the pasties comes from Kilhallon Quality Meats, which sources from the Organic Livestock Farmers Cooperative for Cornwall and Devon, while Cornish Organics is providing the cream and milk for the sweet tarts.
Ingredients also come from other Duchy Originals products, including preserves and lemon curd, produced by Crabtree & Evelyn in Somerset, and the bacon used in the bacon and cheese flans.
Established by HRH The Prince of Wales to promote sustainable farming and food production, the existing Duchy Originals range includes biscuits, fruit preserves, chocolate, tea, bread, hams, sausages and bacon and ready meals.
All profits are donated to The Prince of Wales's Charitable Foundation.
