Ginsters is a company based in Callington in Cornwall, in the southwest of England. The largest pasty maker in the UK in turnover, it specialises in making mass-produced pasties, sausage rolls, sandwiches, pasta bowls and other savoury snacks. Since 1977, it has been owned by Mark and David Samworth.

The Ginsters family were in the business of supplying horse manure to foundries for mixing with sand for the moulds for casting. The business was based in West Bromwich before finally moving to Longwood Lane, Walsall. After the second world war, Geoff Ginster approached his father saying that he wished to move with his family down to the West Country. He asked his father if it would be possible to have his inheritance early in order to so do. Originally moving to Devon, Geoff Ginster started making clotted cream and became very successful to the point where the Milk Marketing Board offered to buy him out. Geoff refused only to be met with the response, “if he did not sell the MMB would cease to supply his business with milk”. Geoff Ginster having no choice moved to Cornwall and started his Cornish Pasty business in 1969. They started the business in a near-derelict egg-packing station, with a staff of four. Geoffrey Ginster started production of pasties from a ‘secret recipe’ he claimed to have obtained from a ship’s cook. Production slowly increased until by 1970 a staff of 30 was producing 48,000 units a day. Initially Ginsters pasties were sold to pubs, cafés, corner shops and other small stores in Plymouth and nearby seaside towns, before expanding further to cover southern England.

In 1977, Geoffrey Ginster retired and sold the business to Samworth Brothers, leading to further growth, modernisation and development. An adjoining factory was acquired, renovated and equipped with modern baking and packing facilities. It was renamed the Tamar Bakery, and was later extended with new, largely automated, machinery. When it went into operation the original Ginsters bakery was closed. In 1984, Ginsters was producing 1.5 million pasties a week and had become the biggest employer in East Cornwall’s private sector. In 1987, a new bakery, named Lynher Bakery after the nearby River Lynher, was built alongside the Tamar Bakery.

In 1990, Ginsters commenced advertising and promotional campaigns to raise awareness of their product. This resulted in Ginsters Original Cornish Pasty being stocked by leading supermarkets, petrol stations, convenience stores and motorway service stations across Britain. Ginsters claim that their Original Cornish Pasty is the biggest selling product in the savoury pastry market, and that during a twenty-year period 450 million of them have been sold
