Thawing IQF Prawns

Only if you really must!

I’d love to say “to each their own” but that just doesn’t cut it when it comes to correctly thawing FishVish’s IQF Prawns. There are essentially only 2 methods of doing this right and the third is “only if you really must”.

  1. When you’ve planned ahead and have time – Overnight in the refrigerator – Take out as many prawns as you need to thaw, place them in a sieve which is placed on top of a bowl and cover the sieve. Place this in the refrigerator overnight. This allows the prawns to defrost very slowly and all the water being created from the melting ice is drained away leaving behind firm prawns. Give it at least 12 hours. When you take them out of the refrigerator, if they are not fully thawed out yet, put them in a zip-lock bag, seal the bag and hold it under cold running water for a few minutes.
  2. When you’re running out of time – Under Cold Running Water – Place the prawns in a  zip-lock bag, seal the bag and hold it under cold running water until they are thawed out. You need to drain and pat them dry since the ice has melted and the water is still in the bag so open the bag, drain the prawns in a sieve or colander and then pat them dry. 
  3. Direct – If you only have a few minutes, hold them under cold running water in sieve without placing them in a bag. It’s important to keep them in a sieve so the water is continuously drained. Pat them dry before doing any marinating or cooking.
    • Never ever thaw under warm water, running or otherwise
    • Never submerge them in water directly – place them in a water tight bag or place them in a sieve, if you must
    • Never use a microwave to thaw them.
It is important to thaw prawns correctly so that they not only retain their firmness but also their flavors. Method 3 can make your prawns mushy as they will absorb water so do remember that not more than a couple minutes under cold running water and pat them dry after thawing.
