Ingredients

• Kombu 7 ounces
• Water 5C water
• Bonito flakes (also called katsuobushi) 3 C
• 5 C Dashi broth

Instructions

Day One

• Cut a few slits in the Kombu (dried kelp) and put in a pot or bowl with all the water, to soak for 24 hours in the fridge.
  
• Kombu is an edible kelp that naturally contains iodine and the flavor of the sea. (If your Kombu is covered with a fine white powder, do not worry as that powder contains a natural forming MSG, or umami.)

Day Two

• Pour the kelp and water into a soup pot.
• Bring up to a simmer (very small bubbles), and cook for ~10min, keeping the water level the same and not boiling. (If boiled, it ruins the taste of the broth.) Remove any scum while cooking.
• After the ~10min remove the Kombu. (Save the cooked Kombu by putting it into a freezer bag.) Turn off the heat and let the water cool to where you can touch the water.
• Add bonito flakes and boil the water again, skimming gunk that might float to the top. Once boiling, turn off the heat, and let pan sit for ~10min until the bonito flakes sink to bottom of pan.
  
• Then strain off the liquid using a sieve and paper towel or cheese cloth. (Put wet bonito flakes into a plastic bag and put in freezer for later use.)
• The left over pale golden liquid is the Dashi.

Notes

This method is a “cold brew” method and, to my taste, makes the best version of dashi.

What to do with the cooked Kombu and Bonito flakes? Make Niban Dashi, a lighter version of the Dashi broth. Put 4C water to boil with leftover Kombu and bonito flakes. Once boiling, immediately lower heat for ~10min while skimming gunk. Add additional 5 grams bonito flakes and once they sink, take the pot off from heat and strain. You will have Niban Dashi broth.

Sometimes I will keep the two version of dashi separate, other times I combine both to make a more uniform tasting broth. So now, what to do with the well-used kelp and fish flakes? I make a seasoning called Furikake, a rice seasoning.

If Vegan: Just use the Kombu + Mushroom Dashi.

This broth can be frozen. Although they say up to 3 months, I have used a 10 month dashi and it tasted just fine.
