I for one love saba, and I love it battera sushi style which is another Portuguese influenced food (well just the name). The word “battera” is derived from the *Portuguese word “bateira” or “small boat”.
*A couple of sources on the web cite (most likely taken from Sushi Encyclopedia) this as “batteria“, but in Portuguese that actually means “drum kit”. The correct spelling is “bateira“, and if you decide to copy’n’paste content, at least give a little credit to helping to set things straight, thanks.
Battera is mackerel, sushi rice, and kelp formed in a wooden box called an oshi wako, and I suppose it looks kind of like a boat although I just wouldn’t accuse it of looking too boaty. #boatymcboatface
The name “mackerel” is confusing because there are over thirty species of, and there isn’t just one.
The term for mackerel means “marked” or “spotted”, but if you want to make it more confusing, the naming convention by the Japanese make it even harder because fish are often named also according to age, region and even time of the season.
So here goes my attempt to spell out a couple of the more popular ones for sushi:
- Japanese Spanish mackerel / Scomberomorus niphonius / Seer fish
- Sagoshi (young)
- Kan sawara (winter)
- Sawara (spring)
Non-Scombrid Mackerels (aji)
- Japanese horse mackerel / Trachurus Japonicus / Jack mackerel
You have to be a marine biologist to understand or properly be able to categorize all of this, so I’ve done all I could.
Not Just Battera
It’s not common at all to be able to eat fresh saba in the U.S. If you do have a chance to eat it raw, it’s only at a good sushi bar or in Japan. The majority of the saba you eat here is typically marinated and preserved in rice vinegar because mackerel spoils real quickly. The marinated mackerel is called shime-saba, and when it’s freshly marinated, it reigns at the top of my list for top neta (sushi toppings). Other ways other than nigirizushi are also sabazushi which is a type of bo-zushi. Think of it like a saba burrito/roll.
Mackerel has an oily flesh packed with nutrients such as:
- Lots of omega-3 fatty acids: you know you need those omega-3’s because your body can’t produce them, but you need them for cognitive functions like memory performance. The other benefits would be to reduce the risk of heart disease.
- Rich in monounsaturated fatty acids: I looked this one up, and it appears it helps reduce bad cholesterol levels in your blood which lower your risk of heart disease and stroke.
- EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid): The American Heart Association says that your body can’t produce them either like omega-3’s, but you need these too. Is that good enough reason?
The positives are that it’ll potentially help with heart disease, strokes, diabetes, blood pressure levels and wrestling tigers bare-handed.
For more information, you can read the articles/resources below:

So, by now I hope you think “fishy” might be a good thing, and your diet will now consist of battera sushi next to your vegetably diet.
Where to Buy
This list is my recommendations on where to buy mackerel although I’m sure you can find it at most Asian grocery stores. I have listed mostly Japanese markets and one Korean market with locations everywhere:
- H-Mart fresh and frozen saba.
- Marukai really good battera, frozen, and fresh saba.
- Mitsuwa good battera, frozen, and fresh saba.
- Nijiya not sure about battera, but I’m sure they have frozen saba.
- Seiwa most likely only frozen saba.
- Tokyo Central not a fan of their battera, but they have fresh and frozen saba.
You’ll want to call ahead to confirm their selection/availability.
