Saba Misoni (Mackerel Simmered in Miso)

Step 1

Gather all the ingredients.

Step 2

Scrape off the ginger skin with a knife (or a spoon) and cut into thin slices. Keep half the slices for cooking the fish and use the other half for the next step.

Step 3

Cut the other ginger slices into thin julienned strips and transfer to a plate. This is for garnish.

Step 4

Cut each fillet in half, in a slanted angle (this creates more surface to absorb flavors). Make a shallow cross incision on the skin side of the thickest part of the fillets.

Step 5

Bring a medium pot of water to a boil. Once boiling, gently put a fillet, one at a time, for a quick blanch to remove the sliminess, smell, and impurities. Scoop up the fish with a fine-mesh strainer or a slotted spoon. Alternatively, you can pour boiling water over the fillets.

Step 6

Quickly shock the fish in the ice bath. And repeat this blanch/ice bath process with the rest of the fillets.

Step 7

Clean the fish in the ice water, removing blood or any impurities. The ice water helps firming up the flesh of the fish as well. Once clean, transfer to a plate/tray and set aside.

Step 8

In a medium/large saucepan, add the Seasoning #1 (4 Tbsp water, 4 Tbsp sake, 2 Tbsp mirin, 2 Tbsp sugar, 2 Tbsp miso (keep the other 2 Tbsp miso for later), and ginger slices.

Step 9

Turn the heat to medium and bring the sauce to a boil while mixing the ingredients.

Step 10

When boiling, place mackerel in a single layer, skin side up.

Step 11

Reduce heat to medium-low and put an otoshibuta (drop lid). Gently simmer for 13-15 minutes. Otoshibuta keeps the fish down and helps the sauce circulate over the fish.

Step 12

Remove the otoshibuta (drop lid). Using the fine-mesh skimmer or slotted spoon, gently take one fillet out to a plate.

Step 13

Now we add the Seasoning #Add 2 Tbsp miso and let it dissolved completely.

Step 14

Put the fillet back in the sauce and drizzle 1 tsp soy sauce.

Step 15

Hold the pot and tilt it around to distribute/mix the sauce with the fish (we use a very little amount of the sauce, so this is the best way to distribute and mix the sauce at the same time). Spoon the sauce over the fish a few times.

Step 16

Turn off the heat and cover with the lid. Let the fish cool for 30 minutes. All Japanese simmered foods apply this "let cool" step so the ingredients can absorb the flavors without overcooking them.

Step 17

Uncovered and turn the heat to medium. Reheat the fish, but make sure to stay around the kitchen so you don't burn the thickened miso sauce. Spoon the sauce over the fish a few times.

Step 18

Transfer the fish and drizzle the sauce.

Step 19

Garnish with julienned ginger strips and optional Kinome.

Step 20

You can keep the leftovers in an airtight container and store in the refrigerator for up to 2 days.
