Some Japanese fermented foods are easy to love.

Miso?

Comforting.

Soy sauce?

Familiar.

Amazake?

Sweet.

And then Japan puts a tiny bowl in front of you filled with pieces of squid fermented with its own internal organs.

Meet shiokara (塩辛).

Salty.

Intensely savory.

A little funky.

And definitely not trying to be everyone's first Japanese food.

But for people who love it?

A tiny bite and a drink of sake can be all you need. 🍶

What Is Shiokara?

Shiokara (塩辛) is a traditional Japanese food made by curing and fermenting seafood with salt and its viscera.

Pronounced approximately:

shee-oh-kah-rah.

The name gives you a clue about the flavor:

塩 (shio) = salt
辛 (kara) = spicy, pungent or strong

Different kinds of seafood can be used, but the version most people encounter is made from squid.

It's usually served in very small portions because its flavor is powerful.

This is not a food you casually pile onto your plate.

A little goes a long way.

What Is Ika Shiokara (イカの塩辛)?

The best-known type is:

ika no shiokara (イカの塩辛)

Ika (イカ) means squid.

Pieces of squid are mixed with salt and typically the squid's viscera, creating a thick, intensely flavored mixture.

As it matures, enzymes and microorganisms contribute to changes in flavor and texture.

The result is one of Japan's most distinctive seafood delicacies.

If natto is famous for its strings...

shiokara is famous for its courage requirement.

What Does Shiokara Taste Like?

Shiokara has a flavor that's difficult to mistake for anything else.

Expect it to be:

Very salty

Deeply savory

Rich in umami

Seafood-forward

Slightly funky

Depending on how it's prepared and aged, the flavor can vary considerably.

The texture of squid shiokara is also distinctive.

The pieces of squid remain chewy while the surrounding mixture is soft and almost sauce-like.

For someone trying it for the first time, the combination can be surprising.

For shiokara fans?

That's exactly the point.

How Is Shiokara Made?

The basic idea behind shiokara is surprisingly simple.

Fresh seafood is cut into small pieces and mixed with salt and viscera.

The mixture is then allowed to mature.

Salt helps control the environment while enzymes naturally present in the ingredients break down proteins and contribute to the food's intense savory character.

Traditionally, this was also a practical way to preserve highly perishable seafood.

What started as preservation eventually became something people valued for its flavor.

A pattern you'll see again and again in Japanese food culture.

Shiokara Is More Than Squid

Squid may be the superstar, but shiokara isn't one single food.

Different seafood can be prepared using similar techniques.

Examples include shiokara made from:

🦑 Squid

🐟 Fish

🦐 Shrimp

🦀 Crab

Different regions have developed their own variations using locally available seafood.

So if you encounter the word shiokara in Japan, don't automatically assume squid.

Although...

squid is a pretty good guess.

How Do Japanese People Eat Shiokara?

Shiokara is generally eaten in small portions.

And there's a good reason.

Its flavor is extremely concentrated.

You may see it served:

🍚 With rice

🍶 With sake

🥢 As a small side dish

🍺 Alongside alcoholic drinks

It's especially associated with the Japanese tradition of otsumami (おつまみ) — small foods enjoyed while drinking.

A little shiokara.

A sip of sake.

Another tiny bite.

This is a slow-food situation.

Why Does Shiokara Go With Sake?

Strong flavors often work well with drinks.

And shiokara has plenty of strong flavor to contribute.

Its intense saltiness and umami make it a classic accompaniment to sake and other alcoholic drinks.

Rather than eating a large serving, you take a small bite between sips.

That relationship between food and drink is important to understanding shiokara.

It's not necessarily meant to be eaten like a bowl of salad.

Think:

tiny portion, enormous flavor.

Is Shiokara Fermented?

Shiokara is commonly described as a fermented seafood product, although the processes involved can vary depending on the recipe and production method.

Salt plays an essential role, while enzymes in the seafood contribute significantly to the breakdown of proteins during maturation.

That process produces amino acids and other compounds responsible for shiokara's characteristic savory flavor.

It's another reminder that Japanese fermentation isn't only about:

rice.

soybeans.

and koji.

The sea gets involved too.

Where Can You Find Shiokara in Japan?

Shiokara can be found in places such as:

Izakaya

Japanese seafood restaurants

Supermarkets

Specialty shops

You may also encounter regional varieties while traveling around Japan, especially in areas with strong seafood traditions.

Because it's often eaten as an otsumami, an izakaya is a particularly natural place to encounter it.

Just don't expect a huge plate.

With shiokara...

small is enough.

Shiokara and Japan’s Fermentation Culture

Shiokara reveals something important about Japanese fermented foods.

They're incredibly diverse.

Miso transforms soybeans.

Nukazuke transforms vegetables in rice bran.

Koji helps create sake and soy sauce.

Natto transforms soybeans into something famously sticky.

And shiokara takes highly perishable seafood and turns it into an intensely flavored preserved food.

Different ingredients.

Different techniques.

Different microorganisms and enzymes.

But the same basic idea appears again:

time can completely transform food.
