Can you eat prawns 2 days after the 2 use-by dates?

The quality of the raw prawns does not depend on the sell-by date. Prawns, when constantly kept in the fridge, after the purchase, last for up to 3 days. If you want your prawns to last longer, consider freezing them. 

Frozen prawns should be fine sitting in the fridge for an extra 1-2 days after thawing. However, this only applies if the prawns were defrosted in the fridge, where they were allowed to sit overnight or for several hours. Cooked and correctly refrigerated prawns stay fresh for about 1-2 days. 

If you left out the prawns on the counter for more than 2 hours, discard them. If the temperature nears or exceeds 90F outside, discard the prawns after 1 hour. Read on if you want to know how to freeze prawns. 

How to store prawns to extend their shelf-life?

Prawns are best consumed fresh. If you cannot eat it right away for any reason, refrigeration is a good option. Snap the head of the prawns. Then pack the prawns in a clean and dry air-tight container. Place the container in the fridge near the back or wherever the ice tray is located inside your fridge. 

This is because an enzyme released from the head of the prawns makes it go mushy and change color. Plus keep the shell on. The shell does the same job as an air-tight container but better. 

Prawns with their shells intact, refrigerated in an air-tight container, preserve better than shelled prawns stored the same way. 

How to freeze prawns?

If you want your prawns to last 6-8 months, freeze them. Make sure you do it before the refrigerated shelf-life of the prawns is over. 

Dip your washed and peeled prawns in a brine solution and keep them in the freezer maintained at 0F. For the brine, dissolve 40g of salt in 1L water. 

We recommend using an air-tight container for freezing prawns so that no spills occur. Make sure to leave an inch of headspace in the container so that the liquid expands without breaking or cracking the container. Always choose a freezer-safe container to eliminate this threat.

If you do not want to bother yourself with the brine making, freeze your prawns in the freezer bag. Before putting them in the bag, wash, peel, and pat dry the prawns with paper towels. Use cold water for washing to maintain the cold temperature of the prawns.

Use wax paper or parchment paper to prevent the prawns from sticking while they freeze. Put a clear label on the freezer bag to keep track of the shelf-life of the prawns. 

Although the freezer bag method is space-friendly, it does not block the odor of prawns from escaping into the freezer. 

What’s the best way to cook prawns?

There are plenty of ways to go about cooking prawns. It all comes down to personal preference. If grilling is your personal favorite method of cooking prawns, then be it. Similarly, we are no one to judge if poaching or pan-frying is your go-to for cooking prawns. 

However you cook your prawns, just do it right. Most recipes that involve cooking shelled prawns will suggest you de-vein the prawns. This is a crucial step as the vein can rupture during preparing, handling, or cooking.

Consequently, the contents of the vein will spill over and contaminate your prawns. Skip this step if the recipe calls for in-shell prawns. 

It is almost everyone’s first instinct to discard the prawn shells thinking they are inedible. We’re sorry if you have been doing this for a very long time because you haven’t experienced the culinary potential of prawn shells.

Next time you de-shell the prawns, set the shells aside. Then boil them to make the flavorful prawn shell stock. Use this stock to cook rice, or boil pasta. You can also add it to soups, sauces, and dips.
