What food was "invented" or discovered in England?

  1762: The sandwich was invented in England. We have a town named Sandwich in the south of England. John Montagu, the Earl of Sandwich invented a small meal that could be eaten with one hand while he continued his nonstop gambling.  
  1837: Worcestershire Sauce (Worcester Sauce) John Lea and William Perrins of Worcester, England started manufacturing Worcester Sauce (Worcestershire). Worcester sauce was originally an Indian recipe, brought back to Britain by Lord Marcus Sandys, ex-Governor of Bengal. He asked two chemists, John Lea and William Perrins, to make up a batch of sauce from his recipe.  
  HP Sauce was invented in England at the end of the 19th century by Mr FG Garton, a Nottingham grocer.
He was down on his luck and couldn't pay his bills, so when Edwin Samson Moore, owner of the Midland Vinegar Company,
offered to cancel his debt with the company and pay him �150 for the recipe, plus the use of the name HP, Garton jumped at the chance. Moore had been looking around for some time for a sauce to manufacture and market. He liked both the taste and the name of Garton's HP Sauce, which had an appropriately patriotic ring to it. The HP stood for Houses of Parliament, as it was rumoured that the sauce had been seen gracing the tables of one of the dining rooms there.
  1902: Marmite was invented in England. Marmite is dark brown-colored savory spread made from the yeast that is a by-product of the brewing industry. It has a very strong, slightly salty flavor. It is definitely a love-it-or-hate-it type of food.  
  Mincemeat was invented in England as a way of preserving meat without salting or smoking it.
