Brown sauce is a condiment commonly served with food in the United Kingdom and Ireland, normally dark brown in colour. The taste is either tart or sweet with a peppery taste similar to that of Worcestershire sauce.
Brown sauce is typically eaten with meals such as full breakfasts, bacon sandwiches and chips.
A combination of malt vinegar (or water) and brown sauce known simply as sauce or chippy sauce is popular on fish and chips in Edinburgh, Scotland.
