A bakery in Cornwall has cooked up a row with Great British Bake Off winner Nadiya Hussain over how a Cornish pasty should be made.

It all began when Nadiya shared a link to her take on the Cornish pasty before last night's new season of Channel 4's The Great British Bake Off, which started at 8pm, reports Cornwall Live.

Quick to defend the integrity of their heritage, Portreath Bakery's Marion Symonds called out Nadiya's recipe, which contained lamb, apple and peas.

In a rather sharp tweet, Marion says the recipe is an "awful take on the Cornish pasty".

She adds that pasties "should never be allowed" to contain peas. Burrrnn.

A further tweet from the Portreath Bakery account questions: "Have you ever eaten a true Cornish pasty? Potato, swede, onion, beef skirt wrapped in a pastry case crimped with plenty of pepper! NO PEAS!"

That's not the end of it...

Nadiya bites back responding: "Perhaps you should eat one of those pasties, raise your sugar levels and jog over to the 21st century."

But if anyone has the skills to school someone over a Cornish pasty, it's Marion.

She is an ambassador for St Austell's new Cornucopia attraction, which houses the first interactive pasty heritage centre and was pasty champion for the Eden Project in 2015.

If that's not enough Marion is on the Cornish Pasty Association and is the mother of the pasty in Mexico.
