Have you ever seen a food that looked strange at first… but turned out to be surprisingly delicious?
In Japan, Shirako (白子) is one of those foods.
Shirako is fish milt, and even many Japanese people hesitate before trying it for the first time. But once you taste it, the experience can be completely different from what you expect.

It’s rich and creamy — almost like a very thick milk — with a smooth texture that slowly melts in your mouth. Surprisingly, it doesn’t have a strong fishy smell.
One of my favorite ways to enjoy it is Shirako Ponzu (白子ポン酢), a simple winter dish where lightly cooked shirako is eaten with a refreshing Japanese citrus sauce.
I found fresh shirako at my local supermarket today and made it at home. Let me show you how Japanese people enjoy this unique seasonal dish.
If you want to recreate this Japanese experience at home, the ponzu sauce makes a huge difference.
How to Make Shirako Ponzu
Before we get started, I know shirako may look a little strange if you’ve never seen it before. But once you try it, you may be surprised by how creamy and delicate it tastes. Keep reading and see how I make Shirako Ponzu at home — you might end up wanting to try it too!
1.Sprinkle a little salt over the shirako.

2.Leave it for about 10 minutes. And rinse gently to remove slime.

3.Briefly boil it for a soft creamy texture.

4.Chill slightly and pour ponzu over the top.

That’s it.
What Does Shirako Taste Like?
Shirako has an incredibly rich and creamy texture — almost like thick warm milk from the sea. It feels slightly sticky and silky at first, then slowly melts in your mouth. Despite being seafood, it doesn’t have a strong fishy smell at all. Instead, the flavor is mild, buttery, and surprisingly delicate.
Because shirako is so rich and creamy, it pairs perfectly with refreshing ponzu sauce. The bright citrus flavor cuts through the richness and makes each bite feel lighter and more balanced. That contrast is exactly why Shirako Ponzu is such a popular winter dish in Japan.
The Secret Is the Ponzu Sauce

To me, this ponzu sauce is what makes Shirako Ponzu so enjoyable — especially for people trying it for the first time. I’ve tried many different ponzu sauces over the years, but I keep coming back to this one because it has a fresh yuzu aroma without being overly sour. Some ponzu sauces can be too sharp and overpower the food, but this one feels balanced and easy to enjoy.
It works beautifully not only with creamy shirako but also with sashimi, steamed vegetables, and many other Japanese dishes. If you’re curious about Japanese flavors and want one ponzu to start with, this is an easy choice.
Final Thoughts
If you ever visit Japan in winter, I highly recommend trying Shirako Ponzu at a sushi restaurant. The rich, creamy texture is something you may never forget.
You can sometimes find it even at conveyor belt sushi restaurants during the winter season, so don’t miss the chance if you see it on the menu.
Tonight, I enjoyed my shirako with tuna and a glass of Japanese sake — a simple but very Japanese dinner.
Bon appétit!
