Introduction


Are you afraid of fermented foods? Was your first experience too strong, sour, stinky, or simply unfamiliar territory that it made you say "never again" to its acidic nature? If you’ve wondered whether fermented foods might support your digestion, but felt intimidated by the taste, this is a gentle place to begin.


In Japanese home cooking, fermented foods are always paired with small dishes of rice, soup, and vegetables as part of an eating method call

Ichiju-sansai. This way, your tastebuds don't get overwhelmed by the fermented food alone.


Sometimes, all we need is a bit of experimentation. You just haven't met the right ferments yet, and trust me, they are delicious and good for you!


Let's start with the basics below! 🌿



1. Miso


Miso Paste in barrels

Perhaps the most quintessential Japanese seasoning out there, miso is found in everyone's kitchen. We have the staple miso soup, miso broth for protein and veggies, and dressings, sauces, and marinades—all with miso as the base ingredient.


Flavor Profile

  • Salty, umami, and earthy (Flavor changes based on the miso color: white, yellow, red, brown or mixed.)


Why Beginners Like It

  • Has a memorable umami flavor

  • Easy on the stomach especially for first-timers

  • A versatile ingredient for all kinds of recipes

  • Contains probiotics to support your gut flora



2. Shio Koji

Shio Koji is another probiotic seasoning that will leave your gut happy. It is made from rice koji, salt, and water that are fermented together. Many home cooks use it as an all-purpose seasoning or marinade. It also tenderizes meat and firms up fish for cooking.


Flavor Profile

  • Lightly salty, slightly sweet, and deeply savory.


Why Beginners Like It

  • Mild flavor doesn't overwhelm taste buds

  • Makes meat and fish tender

  • Adds depth without overpowering a dish

  • Easy to use as a marinade or seasoning



3. Rice Vinegar

Japanese rice vinegar has long been used in Japanese cooking, especially in sushi rice, salads, and light pickles. It is made from fermented rice or sake lees. Compared to many other vinegars, it has a relatively mild acidity (around 4–5%).


Flavor Profile

  • Light, slightly sweet, and delicate.


Why Beginners Like It

  • Mild and not too sharp

  • Brightens dishes without overwhelming them

  • Easy to mix into dressings or sauces

  • Familiar taste for many people



4. Tsukemono

Tsukemono are traditional Japanese pickles that have been part of meals long before refrigeration existed. They are usually served in small portions to refresh the palate and balance richer foods.


Some are fermented slowly, while others are lightly pickled. Both styles are common in everyday meals.


Flavor Profile

  • Fresh, tangy, and sometimes slightly sweet depending on the vegetable.


Why Beginners Like It

  • Crisp and refreshing

  • Usually eaten in small amounts

  • Easy to pair with many dishes

  • Good palate cleanser



🌿 Start Small with Fermented Food


I know ferments can be intimidating to integrate in everyday meals, BUT, you don't have to do it all at once. You just need to take it slow, and try it once a day. Maybe, include pickled veggies for your lunch or pair miso soup with your main protein dish. Once your palate is able to adjust to the acidity or taste, you'll realize it's actually good and addictive. Over time, these attempts will turn into habits making dining a comfortable and healthy experience.


If you’d like to see how you benefit from fermented foods, I explain it visually here:



After watching, ask yourself, "Can I commit to including fermented foods in my diet? Is it sustainable?"

🌸 Gentle Note from Miwa 


Fermented foods are powerful ingredients toward a healthier body, but they work best when they are part of a balanced structure like the Ichiju-sansai method.


If you feel bloated, constantly craving sweets, or unsure how to manage meals, you may not need more information, you just need a proper system. Many of my clients felt the same way before we created a simple, realistic structure together.


In my 60-day coaching program, we gently design a way of eating that fits your real life. It doesn't have to be perfect or restrictive, you simply need the right structure and support. Let's have a chat and transform your meals!
