Colman's of Norwich has become one of the most iconic mustard brands in the world since it started being made in the city more than two hundred years ago.
Now parent company Unilever are reviewing the future of their Norwich operation which could mean closure.
Yet just three years ago the future seemed secure as ITV Anglia reporter Kate Prout looked at the company's proud history.

The Unite union say they are concerned about the future production of Colman's Mustard in Norwich after Britvic's decision to close it's drinks business on the same site resulting in more than 240 job losses.
The production of its Robinsons and Fruit Shoot brands at the site, which is co-owned with Unilever, will be transferred to east London, Leeds and Rugby. The plant will close by the end of 2019.
Now Unilever who own Colman's could be pulling out of the city as well ending more than 200 years of mustard production in Norwich.
Unite national officer Rhys McCarthy said:
Chelmsford MP Simon Burns has met with bosses of soft drinks firm Britvic over its decision to close its factory in the city. Around 230 jobs will be lost when the plant closes next year.
The Conservative said he had been reassured the firm will do all it can to help staff find alternative employment including relocation to other Britvic factories, like Norwich and the company's head office in Hemel Hempstead.
Robinson's squash maker Britvic has announced it will close its factory in Chelmsford and axe 230 jobs in the town.
A £1.4 billion deal to merge Hertfordshire-based Britvic and Irn-Bru owner AG Barr has been referred to the Competition Commission.
The Office of Fair Trading said it could not rule out the possibility of higher prices following a tie-up after surveys suggested Britvic's brands Pepsi and Tango were sufficiently close alternatives to Irn-Bru to raise competition concerns.
Robinsons parent company Britvic reported a slide in profits following the recall of newly-designed bottles of its Fruit Shoot drink.
The soft drinks firm, which recently agreed a £1.4bn merger with Irn-Bru owner AG Barr, saw pre-tax profits slide 19% to £84.4m in the year to September 30.
A proposed merger between Essex drinks manufacturer Britvic and Irn Bru maker AG Barr has been delayed to allow more time for talks.
Britvic, which is based in Chelmsford, and AG Barr announced a new Takeover Panel deadline of November 28 to complete the deal. The merger is reported to be valued at around one point four billion pounds and could create one of the biggest soft drinks firms in Europe.
