Fish and chip lovers in the UK might be surprised to learn that the ‘vinegar’ often used in their favourite dish is not actually true vinegar. While the combination of salt and vinegar is a classic accompaniment to the UK staple of fish and chips, it turns out that many chip shops opt for a synthetic alternative known as non-brewed condiment. In traditional vinegar production, alcohol fermentation is the key process, resulting in various types of vinegars made from sources like fruits, grains, or honey. However, in the UK, non-brewed condiment is commonly used in fish and chip shops. This synthetic liquid is made from acetic acid, water, and flavourings, providing a tangy taste similar to vinegar but without the need for fermentation, making it a quicker and cheaper option for businesses.
Despite the preference for non-brewed condiment in many establishments, some fish and chip shops still offer genuine malt vinegar. Non-brewed condiment provides practical benefits for chip shops, such as cost-effectiveness and an extended shelf life. Furthermore, this alternative is free of alcohol, catering to teetotal customers. In addition to the vinegar revelation, fish enthusiasts may also be surprised to discover that the fish in their fish and chips may not always be the expected cod. Some chip shops may substitute cod with haddock, pollock, whiting, sole, or hake, leading to potential mislabeling issues.
A 2014 study by Oceana found that up to 7% of fish sold in UK shops and restaurants were mislabeled, with other white fish varieties passed off as cod. This misrepresentation could stem from supply chain challenges or cost-related motivations, as cod is typically pricier than other white fish species. Fortunately, recent years have seen a decrease in mislabeling practices, thanks to stricter regulations and heightened public awareness. Traceability systems and DNA testing have played crucial roles in ensuring the authenticity of fish served in fish and chip shops, restaurants, and supplied by suppliers. With these measures in place, customers can enjoy their fish and chips with confidence in the authenticity of their meal.
