How to make Homemade Dashi – Basic Japanese Stock

If you’re unfamiliar with the basics of Japanese cooking, you should start with the basics of dashi (basic Japanese stock). This base is made from dried seaweed called awase dashi, and bonito flakes (salmon roe) and water. The classic method for preparing dashi is to steep post card-sized pieces of dried konbu in water overnight. The monks of Koya-san would then remove the dashi from the water and cook it with the rest of their fish, vegetables, and other ingredients.

  • Quality Ingredients: The quality of your ingredients matters. Use fresh vegetables and high-quality dried shiitake mushrooms for the best flavor.

FAQs about Basic Japanese Stock

Basic Japanese Stock
Start your day with savory oatmeal made using basic japanese stock.
  • Can I store leftover Basic Japanese Stock? Absolutely! Store any leftover stock in airtight containers in the refrigerator. It can be kept for 3-4 days. To store it for a longer duration, freeze the stock in smaller portions and thaw as needed.
  • Can I make a vegetarian version of this stock? Certainly! Omit the dried shiitake mushrooms and use more kombu and additional vegetables like cabbage and daikon for a flavorful vegetarian stock.
  • How can I intensify the umami flavor of the stock? You can enhance the umami notes by adding a small handful of bonito flakes (katsuobushi) while simmering the stock. This adds an extra layer of depth to the flavor.
  • Is there a specific soy sauce to use for the stock? Traditionally, Japanese soy sauce (shoyu) is preferred, but you can use any high-quality soy sauce. If you have dark soy sauce, use it sparingly as it can darken the stock significantly.
  • Can I reuse the solids after straining the stock? While you can reuse the vegetables and kombu, they are often quite flavorless after simmering for so long. It’s better to compost them or discard them after straining.
