Refrigerator Thawing
The refrigerator method is ideal for safely thawing sushi grade tuna while preserving quality. Here’s how to do it:
-
Place the vacuum sealed frozen tuna on a plate to catch any drips.
-
Put the tuna on the bottom shelf of the fridge, where the temperature is the coldest.
-
Allow tuna to thaw slowly over 12-24 hours. A 1-inch thick piece of tuna may take around 12-24 hours to fully defrost.
-
Once thawed, the tuna should still feel very cold. Refrigerator thawing keeps the tuna at a safe 40°F or below.
-
Pat the tuna dry with paper towels before use.
Refrigerator thawing prevents bacteria growth and gently defrosts the tuna without damage.
Cold Water Thawing
For faster thawing, a cold water method can be used. Take care to keep temperatures low and never let tuna sit at room temperature.
-
Place the vacuum sealed frozen tuna in a resealable plastic bag submerged in very cold water.
-
Change the water every 30 minutes so it stays chilled below 40°F.
-
Massage the bag occasionally to evenly distribute the cold water.
-
It may take 2-3 hours for a 1-inch thick tuna steak to thaw using this method.
-
Once thawed, remove tuna from bag, pat dry and use immediately. Do not refreeze.
Monitor water temperature closely when using this quicker thawing method.
