Story Behind this Recipe
Dried horse-mackerel is often sold in packs of 4, and we often have leftovers, since there are only two in the family. I wanted to think of a way to make something good with the leftovers, and I remembered once eating pasta made with saury. I decided to try to make the same dish with horse-mackerel.
You can make this with dried horse-mackerel that's already been grilled. In that case, start at Step 3. The saltiness of the fish may vary, so adjust the seasoning after adding the soy sauce. I recommend using lots of garlic and onions!
