Oyster ketchup is a Victorian English shellfish seasoning documented in Mrs Beeton’s 1861 household manual. The page records the historical formula and serving role as evidence, not as a safe modern recipe.

Chef Alex Perry makes this modern shrimp garum from Gulf white shrimp heads and shells, koji, water and salt. He holds the mash at 60°C for two months, then strains the liquid for use as a seasoning.
