Since 2011, the Cornish Pasty has held protected status under food laws, and can only be made to a specific recipe in the historic county. The London-listed company will not be selling its own-brand pasties in its Cornish stores, however.

Greggs is known for its popular sausage rolls and steak bakes, although it also produces a beef and vegetable pasty. The Saltash store adds to sites Greggs has opened in Truro, St Austell and Launceston. One resident even previously described Greggs’ own alternatives as the “Devil’s spawn”. Greggs, which was founded in 1939 on Tyneside and is popular across the North of England, has faced scepticism from locals fiercely loyal to the traditional Cornish pasty.Īttempts by Greggs to launch in the market have been branded as the “pasty wars”. Roisin Currie, chief executive of Greggs, said the business saw “more scope to open sites” in Cornwall, where the chain only has a small presence. The bakery chain confirmed it had opened its fourth Cornish site, at the U2 Enterprise Park in Saltash, on Saturday, as it unveiled plans to open 150 stores this year with a focus on the South West. It maintains a constant pressure inside the frying chamber to avoid leaks, to prevent the oil from sloshing around and to use less energy to heat the oil.Greggs is cooking up a fresh assault on the home of the pasty, as it sets its sights on expansion in Cornwall. The experiment hardware is automated and closed for safety.

The experiment measured the temperature of the boiling oil as well as temperatures inside the potato – three levels deep. The experiment captured the frying process with a high-speed, high-resolution camera to capture the bubble dynamics such as growth rate, size and distribution, as well as the escape velocity from the potato, the bubbles’ speed and direction of travel in the oil. The experiments were conducted on two ESA parabolic flight campaigns, whereby an aircraft flies in repeated arcs to recreate brief moments of weightlessness. To study how microgravity influences cooking techniques such as frying, a novel experimental carousel-type apparatus was designed to fly and be safe.
