Mentsuyu is convenient and delicious. I used to use storebought mentsuyu, but I wanted to make my own so I looked up recipes online. After several experiment with more or less mirin, sugar and so on, I think that this version is just like the storebought one I used to use.

It's a bother to have to strain the liquid, so I put the bonito flakes in a large tea bag. Dry roast the used konbu seaweed and bonito flakes with sesame seeds and turn into furikake (rice seasoning). The mentsuyu sauce will keep for about a month in the refrigerator. For about 400 ml.
