Danish cuisine , originating from the peasant population's own local produce, was enhanced by cooking techniques developed in the late 19th century and the wider availability of goods after the Industrial Revolution. The open sandwiches, known as smørrebrød, which in their basic form are the usual fare for lunch, can be considered a national speciality when prepared and decorated with a variety of fine ingredients. Hot meals are traditionally prepared from ground meats, such as frikadeller (meat balls) and medisterpølse, or from more substantial meat and fish dishes such as flæskesteg (roast pork with crackling) or kogt torsk (poached cod) with mustard sauce and trimmings. Denmark is known for its Carlsberg and Tuborg beers and for its akvavit and bitters, but amongst the Danes themselves imported wine has gained in popularity since the 1960s.
