Fermented meat around the world
Dry salami, sour pork with rice, matured sheep and aged blubber follow different paths from animal to food. Their stories connect microbes with climate, slaughter, migration and the meals people share.

Shiokara is a Japanese salted and fermented seafood preparation, in which squid or the organs of other fish are matured in salt until the flesh breaks down into a thick, savoury paste that keeps its solids.

Shiokara is a Japanese preparation of salted and matured seafood. The defining feature is that substantial solids remain in the mixture while it matures, so the product is eaten as a dense, savoury paste rather than strained into a liquid. The best-known form is ika no shiokara, made from squid.
The category is wide. Across Japan, the same method is applied to different seafood, including the gut of bonito, sea cucumber intestine and sweetfish gut, and each has its own name and history.
The seafood is salted and matured. Because the solids stay in the mixture, the maturation breaks the flesh down into a paste rather than a clear liquid. The sources do not give measures, temperatures or durations for the general method, so they are not recorded here.
Ika no shiokara is the squid preparation. Shutō uses the gut of bonito, konowata uses sea cucumber intestine and uruka uses sweetfish gut. Each is a separate product with a separate history, and the MAFF account treats them as one family rather than one recipe.
Shiokara is distinct from the regional fish sauces, which are liquids drawn from matured fish. The contrast with those liquid sauces explains why the solids matter.
The reference photograph shows squid shiokara in its own sauce, served in a small bowl. The product is eaten in small amounts as a strong, salty accompaniment.
The MAFF account sets no safe limit or shelf life for home production. Appearance, smell and taste do not establish that a product is safe.
Open questions: the date of shiokara as a named product, and the separate history of each version.
Medieval Japanese literature documents the broader tradition of salted-fermented seafood; the individual products named below need separate histories.
