This Kombu Tsukudani is perfect with rice or as a side since even in small quantities, it packs so much flavour. It’s traditionally quite salty so that it can last long (even with refrigeration) but I love mine with a good balance of sweet and salty so I tend to add more sugar to get it that nice sweetness to balance out the saltiness.

It’s up to you to season yours according to your taste and adjust the sugar as needed–do note that sake and mirin already contain some sugars.

KOMBU TSUKUDANI OR JAPANESE SIMMERED KOMBU

I first tried kombu tsukudani in Japan years ago when I visited a local grocery store that had a wide range of ready made sides and dishes that you could either reheat or enjoy cold. It had a wide selection of sides and salads, as well as of course some Kombu Tsukudani. I love kombu for the umami it gives to soups and dashi but it’s also delicious enjoyed this way with its bite and the flavours its cooked down it.

DRIED KOMBU

• I used 2 dried kombu sheets. Each was around 4×8” (~10 x 20 cm) and 30 g (dried) in total.

The kombu I used for this recipe is from my Kake Udon recipe. I soaked the kombu for my dashi and turned the soaked kombu into this simmered kombu dish.

You can check out my Kake Udon recipe here.

REHYDRATING THE KOMBU

• Skip these steps if you already have rehydrated kombu.
• If not, cut through your kombu using a pair of scissors. I like to fold mine in half and cut around five 1” (2.5 cm) cuts on each side. You can see the video below.
• Place the kombu in a large container or jar. Pour in the water.Leave the kombu and mushrooms to soak in the water overnight. I keep mine refrigerated.

• Thinly sliced the rehydrated kombu.

SIMMERING THE KOMBU

WHAT YOU’LL NEED:

• water
• sake
• mirin
• soy sauce
• dark soy sauce
• sugar

See the full recipe below!

WHAT TO DO:

• Heat a medium sized pan or pot over medium. Once hot, add in the water and kombu. Leave to boil.
• Once it boils, add in the sake, mirin, soy sauces, and sugar. Mix well and leave to simmer for 15-20 minutes until the water is absorbed and the sugars start the coat the kombu. Taste the kombu and feel free to adjust to your taste.
• If your kombu is still a bit hard to the bite, you can add 2-3 tbsp more water and leave to cook a bit longer.
• Once cooked and seasoned to your taste, turn off the heat and mix in the sesame seeds.

SERVING AND STORING THE KOMBU TSUKUDANI

• Transfer to air-tight containers and allow to cool completely before refrigerating. This will be good refrigerated for 2 weeks, or even longer. I love mine served over rice. You can enjoy yours with noodles, or as a delicious appetiser or side dish.
