Potatoes In Two Very British Meals

* Fish and chips

Fish and chips (sometimes written "fish 'n' chips") consists of deep-fried fish (traditionally cod, haddock or flounder) in batter or breadcrumbs with deep-fried chipped (slab-cut) potatoes. fish and chips remains very popular in the UK and in areas colonised by British people in the 19th century, such as Australia, New Zealand and parts of North America.
The long-standing Roman Catholic tradition of not eating meat on Fridays - especially during Lent - and of substituting fish for other types of meat on that day - continues to influence habits even in predominantly Protestant societies. Many cafeterias and similar establishments, while varying their menus on other days of the week, habitually offer fish and chips every Friday.

* Bangers and mash

Bangers and mash, also known as sausages and mash, is an English dish made of mashed potatoes and sausages, the latter of which may be one of a variety of flavoured sausage made of pork or beef or a Cumberland sausage. The dish is usually served with a rich onion gravy. It can also often be found served with fried onions.
This dish has a particular iconic significance as a traditional London working-class dish.
