How to thaw imitation crab (surimi)
In the fridge
Safest. About 24 hours per 2.3 kg (5 lb); small packs overnight. Raw meat and seafood then keep 1–2 more days.
In cold water
Seal it in a leak-proof bag, submerge, and change the water every 30 minutes. About 30 minutes per 0.5 kg (1 lb). Cook right away.
In the microwave
Use the defrost setting and cook immediately, because parts of the food may start to cook.
How to reheat imitation crab (surimi) safely
Reheat to 74°C (165°F)
Check the thickest part with a food thermometer; it should be steaming hot all the way through.
Only once
Reheat just the portion you will eat. Each cool-and-reheat cycle gives bacteria another chance.
Cover and stir
In the microwave, cover the dish and stir halfway so there are no cold spots.
From the freezer
Thaw in the fridge first, or reheat straight from frozen and allow extra time.
