Salsa Lizano, ("salsa" means "sauce" in Spanish), is a Costa Rican condiment developed in 1920 by the Lizano Company.
 It is now a product of Unilever.
 It is a thin, smooth, light brown sauce (akin to such condiments as HP Sauce or Worcestershire sauce).
Marie Rose sauce (known in some areas as cocktail sauce or seafood sauce) is a British condiment made from a blend of tomatoes, mayonnaise, Worcestershire sauce, lemon juice and pepper.
 A simpler version can be made by merely mixing tomato ketchup with mayonnaise.
 The sauce, as well as prawn cocktail, which its alternative name of cocktail sauce comes from, was invented in the 1960s by British cook Fanny Cradock.
Oysters Rockefeller consists of oysters on the half-shell that have been topped with a rich sauce of butter, parsley and other green herbs, and bread crumbs, then baked or broiled.
 Lemon wedges are the typical garnish.
Takoyaki is a ball-shaped Japanese snack made of a wheat flour-based batter and cooked in a special molded pan.
 It is typically filled with minced or diced octopus ("tako"), tempura scraps ("tenkasu"), pickled ginger, and green onion.
 Takoyaki are brushed with takoyaki sauce (similar to Worcestershire sauce) and mayonnaise, and then sprinkled with green laver ("aonori") and shavings of dried bonito.
 There are many variations to the takoyaki recipe, for example, ponzu (soy sauce with "dashi" and citrus vinegar), goma-dare (sesame-and-vinegar sauce) or vinegared dashi.
Brown sauce is a traditional condiment served with food in the United Kingdom and Ireland, normally dark brown in colour.
 The ingredients include a varying combination of tomatoes, molasses, dates, apples, tamarind, spices, vinegar, and sometimes raisins or anchovies.
 The taste is either tart or sweet with a peppery taste similar to that of Worcestershire sauce.
 It is similar to brown sauce marketed as steak sauce in the United States.
Oysters Kirkpatrick, also called Oysters Kilpatrick, Kirkpatrick and oysters, or Oysters Philpatrick, is a classic English recipe involving oysters, cheese, Worcestershire sauce and bacon.
Henderson's Relish, known locally as 'Enderson's, Hendo's, Reli or simply "Relish", is a spicy and fruity condiment, similar in appearance to Worcestershire sauce, but which contains no anchovies.
 It is made of water, sugar and spirit vinegar with a selection of spices and colouring.
 Some adherents favour it due to its unique taste, and some out of regional loyalty.
 It is also vegan.
 The comedian Tom Wrigglesworth said of Henderson's Relish that while outsiders think the condiment is Sheffield's answer to Worcestershire sauce, Sheffielders think it is the answer to "everything".
 Certainly Henderson's Relish has an extremely loyal following among the people of South Yorkshire.
Cheddar sauce, cheddar cheese sauce, or cheese sauce is a traditional sauce used in English cooking.
 The sauce is based upon white sauce, which is known as one of the 'mother sauces' and cheddar cheese.
 It is could be seen as an English equivalent of the French Mornay sauce (itself a variant of Béchamel sauce traditionally mixed with half Gruyère and half Parmesan).
 The sauce is made by adding an amount of cheddar cheese to white sauce and then spiced using English mustard, Worcestershire sauce and pepper among other ingredients.
Oysters Bienville is a traditional oyster dish in New Orleans cuisine.
 It is served at some of the city's renowned restaurants, originating at Arnaud's.
 Ingredients include shrimp, mushrooms, bell peppers, sherry, a roux with butter, Parmesan cheese and other lighter cheese, as well as bread crumbs.
 The oysters are baked in the shell or can be made in a small casserole dish or au gratin dish.
