If you love natto but are not too fond of its stick-to-your-mouth texture, then this natto miso soup will be perfect for you! Let's learn how to make it!

Natto is a superfood!
It contains an abundance of essential vitamins and minerals, including vitamin K2. The healthy bacteria in natto aid digestion by boosting the immune system!
You know that it's healthy, but you don't like the stickiness?
The consistency of natto changes when it's heated. When you put in miso soup, the stringy texture dissolves into a more solid one, making eating for those who don't like those pesky strings easier!

- It's up to your preference to mix natto before adding to the pot or not. If you don't like the smell, it's better not to mix it. If you want to taste the umami, it is better to mix it.

curious how mixing changes the taste of the natto? isn't mixing just stirring? tia

Hi Debra, thanks for your comment! Natto's gooey strings are the key. They contain umami elements, and the more you stir, the more these elements increase (more savory). You can find comparison photos (stirring 20 times and 400 times) in this recipe - https://chefjacooks.com/en/natto-gohan-recipe/ I hope it helps!

When we put natto in misoshiru (AKA nattojiru), we typically chop the natto into smaller pieces. We also chop the natto into small pieces when we make nattomaki.
