If you're anything like me and always manage to forget to take fish out of the freezer before heading off to work, finding a way to defrost fish quickly is essential to stop a house full of people wasting away if they don't get fed within the next hour.

To defrost fish or prawns quickly, remove the fish from its packaging and place it in a sandwich bag, ziplock bag or anything else you have to hand that will keep the fish sealed. 

Fill a pan or bowl with cold water and submerge the fish with the bag sealed. Don't be tempted to use warm water to speed up the process, as this will encourage bacterial growth.

If the fish floats in the water, weigh it down with a jar or tin.

Depending on the size of the fish, it can take 20 minutes to 1 hour to defrost. If you'd like it to defrost a little faster, replace the water every 10 minutes.

When it has completely defrosted, remove the fish from the bag and cook immediately.
