Anchovy Extract is a thick, oily sauce about the consistency of ketchup pressed from anchovies.
Some brands, such are "Burgess Genuine Anchovy Essence", are pinkish; others are nut brown.
Sometimes additional seasoning is added.
The extract has a very strong anchovy taste, as is to be expected; use it sparingly to add a savoury tang to meat dishes.
Some recommend it as a substitute for Asian fish sauce, or Roman garum.
