In Japan, “Saku” means block. Due to its uniformity, Tuna Saku is the preferred product for sashimi, ahi sushi, and pan searing. Our thin, center-cut Yellowfin Tuna Saku is prized for its tenderness and sweetness, making it particularly ideal for nigiri.

Our KS Signature Yellowfin Tuna Saku has a more pronounced taste than other tuna species due to the higher fat content and because we harvest and process within hours of being landed. In fact, Yellowfin sashimi is a delicacy that is often served in high-end seafood restaurants.

We all know how healthy seafood is to eat; however, to enjoy it fully, we recommend the following suggestions to Make It Easy!

Fish Fillets

- Sear Medium to High

- 3 to 5 minutes

- Max Finish Temp 145°F

Fish Portions (6-8oz)

- Max Finish Temp 145°F

- Seafood Should be Flaky

Shrimp

- Sear Medium to High

- 3 to 5 minutes

- Finish Temp 130-140°F

DON'T OVERCOOK...SHRIMP IS LOW IN FAT & COOKS FAST

SCALLOPS

- Sear Med. High to High

- 45-90 Seconds per side

- Finish Temp 120°F

DON'T OVERCOOK... SCALLOPS ARE LOW IN FAT & COOK FAST

LOBSTER - BAKED

- Pre-Heat Oven to 350°F

- Baked for 15 minutes

- Use a meat thermometer (140-145°)

- Brush with butter frequently

LOBSTER - BOILED

- Boil Salted Water

- Reduce to Low Bubbling

- 3 to 5 Minutes (3-6oz Tail)

- Add 1 minute for each additional ounce

- Cool immediately in ice water

Please Note: The above guidelines are suggestions only. The average time depends on the size/amount of seafood portions. Stoves and pans also vary in performance, so check color and texture regularly to achieve perfectly cooked seafood. Please use a meat thermometer for accuracy.

Thawing frozen seafood properly is significant not only to ensure the quality of the seafood but also to prevent health risks. For example, all of our seafood has a protective glaze of water to prevent freezer burn-in to ensure quality. Once thawed, gently pat away any excess moisture from the glazing as soon as possible.

We recommend that you follow the USDA’s instructions on safe food handling, which can be found here. We also recommend that all cooking instructions are followed and that you use a food thermometer to ensure that all seafood and other applicable items are cooked to the USDA’s recommended internal temperatures, which can be found here.

Here are a few simple ways how to defrost:

The Refrigerator Method

It might be the longest, but thawing seafood in the refrigerator is undoubtedly the safest way to thaw any protein such as seafood. It also protects the quality of the seafood, providing the best quality-control method. For example, for our Individual Frozen Portions (IFP) or Individually Quick Frozen (IQF) bags like our shrimp and scallops, it can take up to 12- 24 hours to thaw. Please remove from the original package, plate, and cover, or at a minimum, puncture the plastic packaging. Once melted, seafood lasts up to three days in the original packaging. Do not refreeze after thawing.

The Water Method

Here’s how it works:

IFP Portions: Place the seafood in a bowl of cold water (not warm or hot as that starts the cooking process) in the kitchen sink. Change the water now and then or place a constant drip/spray of water to control the temperature. Check the seafood after one hour – it should be fully thawed by then. Cook immediately after thawing.

IQF bags:

Place the desired quantity of seafood (scallops/shrimp) that you will use into another resealable bag.Replace unused IQF seafood immediately back into the freezer.Submerge the sealed bag in a bowl of cold tap water.Let the bag sit in the water until it’s completely thawed, changing the water every 30 minutes, if necessary.

We don’t recommend running under cold water outside of the bag. Cook immediately after thawing.

The Microwave Method

Not always the favorite way, but it’s fast, and the microwave method is undoubtedly the quickest of the three. Still, it’s the least preferred method to preserve the seafood’s quality. But if you forgot to take it out of the freezer and are in a hurry, here’s what you do: make sure you puncture the plastic before placing it in the microwave. Use the “Defrost” function and set the time according to weight. Cook immediately after thawing.

Only From Harvesters We Trust

Our KS Signature Yellowfin Tuna is hand-caught by fishermen in the pristine Laccadive Sea located between the Maldives and Sri Lanka and the Java Sea off the coast of Indonesia, and off the coast of Vietnam. Because they are hand caught, there is no harm to any by-catch, and each tuna is pulled onto the boat and iced immediately.

The catch is brought back to shore as soon as possible to greatly reduce the stress on the tuna and increase the quality significantly as compared to “long line” tuna.

Our KS Signature Yellowfin Tuna leads the way for food safety and quality because of our commitment to never using any additives and our uncompromising harvesting methods and processing protocols.

Review

I was excited for sushi night with my friends but the delivery was a day late and the fish was thawed out and there was no dry ice left. I gave it the benefit of the doubt and opened the package and it smelled. It was also very light color. I couldn’t find a number to call so I messaged on messenger and than was blocked so I couldn’t contact the company.I payed a lot of money for fish I couldn’t eat.

Too many purchases required

The fish was good, but your business model requires too many purchases for my liking. You offered free shipping with $150 purchase (maybe $120, I can’t recall), but your website would not allow me to check out until I hit that mark. I feel like this was intentionally manipulative. I will consider using this service again, but I will know what I’m in for before I start the process.

Excellent Tuna

It's not easy finding tuna of this quality. Like all of KnowSeafood's fish, it arrived perfectly packaged, always fresh and delicious. I couldn't find this quality at my local market and am thrilled that I can get this tuna delivered.

What Is BEYOND Delicious?

KnowSeafood’s Yellowfin Tuna Saku is the answer to question posed. Turned it into poke with a perfectly ripe avocado and arugula micro greens, our new fav addition. I cannot overstate the degree to which KnowSeafood has improved the quality of my life. KNOWING there is always a delicious seafood dinner in the freezer, 30-40 minutes away via defrosting in cold water, is the degree of food comfort I have ever experience.
