Here's what you'll need. Let's get started!
First, rehydrate the wakame seaweed in water. If you don't have time, you can also use them dry.
Dilute the dashi powder in 1 L of water according to the amount indicated on the package and bring to a boil in a saucepan.
You can dilute it with Japanese chopsticks. If you don't understand the instructions on the back of your package, start with a tablespoon. It is better to add more if needed than to put too much.
Cut the tofu into small cubes.
Add it to the pan. Heat for about 5 minutes.
When the water starts to simmer, turn off the heat and add the wakame seaweed. Do not alter their properties, so avoid leaving them too long in the heat.
Take your strainer and put 2 tablespoons of miso inside. Dilute the miso paste with a whisk or with Japanese chopsticks. It is very important to do this off the heat because too much heat will make the miso lose all its properties and it will become more bitter.
If you don't use a strainer, you will have trouble diluting the miso in the soup. You should know that there are different miso with different strengths.
Slide it into the colander.
And dilute it little by little until there is nothing left in the strainer.
Taste and add miso paste if necessary. Be careful not to add too much miso paste at once.
Miso soup should be very light in flavor and not too salty because its main purpose is to 'rinse the palate' between each bite. A miso soup that is too strong in taste could make the whole thing nauseating. It is up to you to judge according to your personal taste.
Serve immediately in shiruwan bowls and enjoy! At the last minute, you can add chopped chives.
