Mushroom ketchup is a variety of ketchup that uses mushrooms as its main ingredient. It is one of the original ketchups, which probably got its name from an Asian fish sauce called ketsiap. Ketchup was originally a catch-all term for different liquid condiments, which could be made from grapes, walnuts, or mushrooms. The original mushroom ketchup was made from wild mushrooms and is thought to have originated in China over 2000 years ago. It was brought to the UK in the 1600s and became popular, with several commercial brands producing mushroom ketchup that is still available today.

History: Ketchup's history started over 2000 years ago in China, where it began as a fermented fish sauce
Ketchup, or catsup, has a long history that began over 2000 years ago in China. The earliest version of the sauce was a fermented fish sauce, similar to the nuoc mam of Vietnam or the nam pla of Thailand. In the Fujian dialect of Chinese, the word "ketchup" or "ke-tchup" meant "preserved fish sauce". This sauce was a pungent, caramel-coloured liquid made from salted and fermented anchovies.
By the 1700s, British and Dutch merchants had brought ketchup to Europe, where cooks attempted to recreate the recipe with various ingredients, such as mushrooms, oysters, anchovies, and walnuts. The first known printed recipe for ketchup was published in 1727 in Eliza Smith's "Compleat Housewife". In the 18th century, ketchup recipes began to appear in English and American cookbooks, with mushroom ketchup being one of the most popular varieties. This variety was made by packing whole mushrooms in containers with salt, allowing the liquid to fill the container, and then boiling the mixture. Spices such as mace, nutmeg, and black pepper were added, and the final product was a dark-coloured liquid derived from mushroom spores.
In 1812, American horticulturist James Mease created the first known recipe for tomato ketchup, which included brandy but lacked vinegar and sugar. Soon, tomato-based ketchup recipes began to spread throughout Europe and the USA, often including previous additions like oysters or anchovies. However, it was not until 1876 when Henry J. Heinz began producing ketchup with very ripe red tomatoes that the sauce gained widespread popularity. The addition of more vinegar and sugar, along with natural preservatives like pectin, resulted in a product that could be easily conserved and sold. By 1905, Heinz had sold 5 million bottles of ketchup, and it had become an essential part of American cuisine.

Preparation: Preparing mushroom ketchup involves packing whole mushrooms with salt, allowing time for the liquid to fill the container, then cooking them
Mushroom ketchup is a style of ketchup that is prepared with mushrooms as its primary ingredient. The process of preparing mushroom ketchup involves packing whole mushrooms into containers with salt, allowing time for the mushrooms to release their liquid, and then cooking them.
To begin, you will need a large container and some fresh whole mushrooms. The mushrooms should be packed tightly into the container and covered with salt. It is important to use enough salt to cover all the mushrooms, ensuring that they are well-preserved. This process of drawing out the liquid from the mushrooms through the use of salt is known as "curing" or "brining". The container is then sealed and stored in a cool, dry place.
Over time, the salt will draw out the liquid from the mushrooms through osmosis. This process can take several days to weeks, depending on the amount of mushrooms and the temperature of the storage location. It is important to occasionally check on the mushrooms and ensure they are fully submerged in the liquid. If needed, additional salt can be added to speed up the process.
Once the mushrooms have released enough liquid to fill the container, the next step is to cook them. The mushrooms and their liquid are transferred to a large pot and heated on a stove. The mixture is brought to a boil and then reduced to a simmer. Spices such as mace, nutmeg, black pepper, and garlic powder can be added at this stage to enhance the flavour.
The mixture is cooked until the mushrooms are soft and the liquid has reduced, becoming more concentrated in flavour. This process can take several hours, depending on the amount of mushrooms and the desired consistency of the final product. Once the cooking is complete, the solid mushroom pieces are separated from the liquid through straining or pureeing, leaving behind a thick, dark brown liquid – the mushroom ketchup.
The ketchup can then be bottled and stored. It is important to use sterilised bottles and seal them properly to ensure the ketchup lasts for several months. The final product will have a deep, earthy flavour with a hint of saltiness and the rich taste of mushrooms.

Its savoury, umami taste can also complement Italian, Chinese, and British cuisine, showing its versatility across different culinary traditions.
In addition to being a condiment, mushroom ketchup is an excellent ingredient for creating complex sauces. It can be used as a base or added to other ingredients to make unique sauces. For instance, it can be combined with cream cheese to create a delicious spread or dip. It is also a key ingredient in "camp ketchup", a historical recipe that includes beer, white wine, anchovy, shallot, ginger, spices, and other ingredients, which are combined and allowed to sit for 14 days before bottling.
