When you get Natto products from Asian grocery stores and open a package, you’ll find a small packet of Natto beans. (and Japanese “Karashi” mustard).
No doubt it’s the sauce for the Natto beans, and we call “Natto no Tare”.
Natto sauce is much more something than soy sauce to make Natto delicious, and we have no trouble getting the sauce if we purchase Natto.
However, what we can do when we make homemade natto at home?
As I said, the natto sauce has much more something than using only soy sauce, and here is the recipe to solve your question.
Actually, Natto sauce is super easy to make if you have all ingredients in your kitchen.
You can make the authentic Natto sauce in just 10 minutes.
6 Ingredients You’ll Need For Natto Sauce

- 1½ tbsp of Sugar
- 2 tbsp of Japanese Sake/white wine
- 1 tsp of HONDASHI powder/dashi powder
- 1 tsp Vinegar
- 3 tbsp Japanese Dark Soy sauce
- 2 tbsp Water
*Optionally, you can use mirin instead of water and sake.
If you are going to use mirin,
Reduce 2 tbsp of sake to 1 tbsp.
Reduce 1.5 tbsp of sugar to 2 tsp of sugar
Mirin Is Essential In Your Cooking?
Mirin is essential to make Japanese food at home, do you believe this myth?
I stopped using mirin when I lived in Nagoya, (20 years ago!) and still have no problem in my cooking life.
Indeed, Mirin is one of the top traditional condiments in Japan, has a long history, and is often used in Japanese cooking.
The purpose of using mirin is mainly to add Umami flavor, and mild sweetness, definitely making the deep savory flavor in the dish and often used for giving the glaze to the dish.
Mirin is the condiment to upgrade the dish while adding a mild sweet rich savory flavor and shiny glaze.
So why I don’t use Mirin is because “pricy”, “the dish likely comes out the same flavor”, and “need to the just right amount for cooking”.
Recently, the mirin price seems dropped down due to the Japanese food trends and it is easy to get in US grocery stores.
It is up to you to add mirin to your pantry condiments, but, I’ll tell you popular mirin substitutes if you don’t collect international condiments just for it like me.
The recipe I made below already tells you the ingredient amount in case you don’t use Mirin.
Mirin Substitutes
Mirin contains alcohol and sweetness, so makeup “mirin” with ideally Japanese sake (but you can use white wine/sherry) and sugar.
Raw cane sugar is better to use for natural mild sweetness.
The ratio of Japanese sake (or white wine/sherry) to the sugar is 3:1. If you want 1 tablespoon of mirin, mix 1 tablespoon of sake with 1 teaspoon of sugar.
You can also use honey instead of sugar.
Honey is 1.3 times sweeter than white sugar, therefore, reduce the amount of honey in the ratio.
As a guide, the ratio of Japanese sake to honey is 3:0.8.
The nice thing about using honey is adding a glaze like using mirin to your dishes. Also, the natural sweetness of honey will add a touch of class to any dish.
What’s Hondashi Powder
When you make a big batch of Natto sauce, you can use authentic Japanese dashi broth made from dried fish, bonito flakes, or dashi kombu (dried kelp).
Yet, I don’t think you want to make “that much” to enjoy homemade natto beans at home.
Hondashi powder/ dashi powder is a handy item to make Japanese cuisine easily and quickly without making Dashi broth with the sensitive picky process to make.
Ajinomoto “Hondashi” is a staple granule soup stock powder in Japanese home cooking which is a versatile seasoning that easily and quickly adds savory flavor to the dish.
There are many products of granule-type Japanese “dashi” powder, and “Hondashi” is a product of Ajinomoto.
If you are looking for authentic Japanese flavor, hondashi is a must-item in your pantry.
Ajinomoto Hondashi contains monosodium glutamate (MSG) extracted but all from natural raw materials such as kelp, bonito flakes.
If you still prefer Non-MSG, addictive-free Japanese dashi products,
go for this post and I’ll introduce non-MSG dashi broth that you can get.
