SHOPPING TIPS |

MISO:

Dried KOJI in a grocery store

This is one of the best quality miso options widely available in the U.S. market.


The ingredient list is exactly how miso should be:

  • Rice koji

  • Soybeans

  • Salt

  • Water

Nothing else.


It is:

  • Made in Japan

  • Gluten-free

  • Simple and traditional

SOY SAUCE KOJI:

Make Your Own Soy Sauce Koji at Home:

Homemade soy sauce koji using high-quality soy sauce and rice koji allows you to avoid preservatives. The flavor is noticeably more balanced when made fresh.

šŸ‘‰ How to Make Soy Sauce Koji


Pre-made soy sauce kojiĀ is also available at Japanese grocery stores if homemade one isn't for you.

Look for:

  • RefrigeratedĀ product

  • Simple ingredients (soy sauceĀ + rice kojiĀ only)

  • No added sugarĀ or unnecessary additives


Because this is a live fermented product, it is rarely available online in good condition due to refrigeration requirements. Local Japanese markets are your best option.

Choose clean, simple ingredients for best flavor.

AMA (SWEET) KOJI:

Ama kojiĀ is rarely available as a standalone product in stores. I always recommend making it at home if possible, since it is simple and contains only rice koji and water.

šŸ‘‰ How to Make Ama Koji


If you prefer a ready-made option, Hakkaisan’s Koji Amazake is very close to homemade ama koji. It uses only high-quality koji and water, without added sugar or unnecessary ingredients. You can often find it at Japanese grocery stores.


Choose the simplest ingredient list possible — quality matters.


Sake (Drinking-Grade)


Use realĀ sake — notĀ ā€œcooking wine.ā€ Cooking wine often contains added salt and flavor enhancers that alter your dish. Choose simple-ingredient sake (rice, water, koji). Think of it like cooking with good wine — quality matters.


Hon Mirin (ęœ¬ćæć‚Šć‚“)


Always look for ā€œHon Mirin.ā€ AvoidĀ ā€œmirin-like,ā€ ā€œaji-mirin,ā€ or ā€œsweet cooking wine,ā€ which often contain added salt, sugar, and additives. True "hon mirin" provides natural sweetness and depth without altering the balance of your dish.
