Prawns are a common ingredient in New Zealand cuisine. However, some critics point to environmental and social concerns relating to the farming of prawns in Southeast Asia.
The good news is that some prawns available locally are ethically produced and sustainable, although there is a lot of work to be done.
1. Thaw in cold water
If you have frozen prawns NZ, defrost them before using them. This is especially important for raw prawns, which should never be cooked without first thawing to ensure they’re soft, juicy and well-cooked.
To thaw prawns, you’ll want to use cold water. This is because hot water can cause the prawns to cook faster than you’d like. It also means the prawns won’t be as tender when you serve them.
The best way to thaw your prawns is to place them in a colander and run them under cold water for a few minutes. This will ensure that they all melt evenly.
Another option is to place the prawns in a bowl and then cover them with ice cubes to help them defrost more quickly. Once you’ve thawed the prawns, rinse them thoroughly with cold water before cooking them.
You can also place them in a freezer bag, but this may give the prawns a smell when you open them. You’ll also need to take care that you remove the prawns from the bag before eating them so they don’t stick together.
If you have time to thaw the prawns in the refrigerator, this is probably the safest way. They should take about 8 hours to defrost, and you can transfer them to an airtight container and store them in the fridge for up to three days.
But if you’re in a rush and don’t have time to wait for the prawns to defrost in the refrigerator, the next best option is to thaw them in water. This is because it can be much quicker than melting them in the oven or salt water, and it will keep your prawns fresher than if they were thawed in the freezer.
However, using this method, you must change the water every 30 minutes, as it can become warm in the container. You should also re-check the frozen prawns NZ to ensure they’re wholly thawed and are not still moist, as this could be dangerous for the prawns.
2. Thaw in salt water
When you freeze prawns, you will want to be sure they are thawed well before cooking. This will ensure they stay fresh and flavoursome. The best way to thaw them is to soak them in cold water and run them under the tap. However, if you do not have this option, you can simply pour them into a container of salt water and freeze them. This method will keep the prawns fresh for up to eight months.
Alternatively, you can cook your prawns and freeze them in the shell. The shell will help insulate the prawn and prevent them from becoming dry and brittle when frozen. You must defrost them before eating them, so do this in the fridge and tread carefully.
You can also freeze prawns raw but shelled, which is the preferred way to prepare them for freezing. To do this, create a brine with one teaspoon of pickling salt (salt without iodine) and one litre of clean water. You must wash your prawns thoroughly before placing them in the freezer bag.
Before preparing your prawns, remove any heads and tails so they will not thaw. This is especially important with spot prawns, as they will soften and deform if you leave them on their head.
You must hold the prawn at the back of its carapace (head) to remove the head and vein. This can be tricky, so using a pair of solid hands may be helpful.
After removing the head and vein, you can peel the shell. Spot prawns are tough to peel when fresh, as the flesh will stick to the surface. To peel the cover, peel the body’s first two segments back and then pinch out the meat.
When preparing your prawns for freezing, store them in a cool place, and do not forget to label the containers and bags with the freezing date. This will ensure you can easily find them when you need to defrost them.
3. Thaw in tap water
If you have some frozen prawns NZ you want to defrost; there are a few different methods that you can use. The first method is to use cold water, which will speed up the process and keep the prawns safe from any bacteria that may be present in the water.
You should only use cold water to defrost your prawns because warm or even hot water will create a situation where bacteria can breed and cause food poisoning. To prevent this, change the water in the bowl frequently.
A great way to do this is to place a mixing bowl in the sink and fill it with cold water. This will ensure that the prawns are completely submerged and can defrost quickly.
