The good news is that making tsuyu sauce at home is easy. So it’s a great way to save money, especially if you make it in larger batches! I’ve included a recipe for 2 cups of this delicious dashi-flavored tsuyu sauce to keep things simple. You’ll need some katsuobushi (bonito flakes), and I recommend Yamahide Hana Katsuo Bonito Flakes because you can buy it in 1 lb bags, and it’s more budget-friendly that way.
Grab a saucepan and pour in the sake, mirin, and soy sauce. Then add in the dried bonito flakes and the piece of kelp.
Bring everything to a boil. Turn down the heat to low and simmer for about 5 minutes.
Turn off the heat and let your sauce cool down.
Remove the piece of kelp and strain the mixture using a sieve.
Notes
The end result is a concentrated tsuyu, and you have to dilute it before use.To store this men tsuyu, transfer it to a glass jar and store it in the fridge for up to 30 days.Just a heads up: tsuyu is high in calories, sodium, and sugar because of the soy sauce, mirin, and sake.
