Navigating the world of frozen seafood online can feel like a gamble. You see terms like "Jumbo" and "King," but what do they actually mean for your dinner? As a home cook, you want value, flavour and convenience, not marketing hype. Getting your prawns delivered UK-wide is simple, but choosing the right ones requires a bit of know-how.
Many shoppers find themselves disappointed when their delivery arrives. The prawns are smaller than expected, shrink significantly during cooking or are inconveniently frozen in a solid block. Let's look at the common pitfalls to avoid so you can buy frozen prawns online with confidence.
To ensure you get exactly what you need for your recipe, focus on these key product specifications. They cut through the jargon and tell you the real story of what's in the bag.
The first decision is whether you need raw or pre-cooked prawns. This choice depends entirely on how you plan to use them.
raw king prawns or other varieties, their uncooked state allows them to absorb the flavours of your marinades, sauces and spices. They are ideal for curries, stir-fries, paella and barbecues. Cooking them yourself gives you complete control over the final texture.cooked peeled prawns are ready to eat once thawed. They are perfect for quick meals like prawn cocktails, salads, sandwiches and pasta salads. As they are already cooked, they only need to be gently warmed through if being added to a hot dish at the last minute to avoid becoming tough.How the prawn is prepared before freezing makes a huge difference to your prep time and the final flavour of your dish.
head on shell on prawns because the shell and head lock in moisture and impart a deeper, more intense seafood flavour during cooking. The shells and heads can also be used to make a rich, flavourful stock for soups and sauces. This option requires more prep work but delivers a superior taste.Ignore vague marketing terms and look for the size count on the packaging. This is usually written as two numbers, like 20/30 or 40/50. This range indicates the number of prawns you can expect to find per pound (lb) or kilogram (kg).
large frozen prawns per kg.This number is the most reliable indicator of size, allowing you to choose precisely what you need, whether it's impressive frozen tiger prawns for the grill or small shrimps for a salad. Also, look for IQF (Individually Quick Frozen) on the label. IQF prawns are frozen separately, not in a block, allowing you to take out only what you need.

1. What does IQF mean for frozen prawns?IQF stands for Individually Quick Frozen. This means each prawn was frozen separately before being packaged. The main benefit for home cooks is convenience; you can easily take out the exact number of prawns you need from the bag without having to defrost a large, solid block. This helps with portion control and reduces food waste.
2. Can I cook prawns from frozen? For smaller, peeled prawns being added to a soup or curry, you can often cook them directly from frozen, though you may need to add a few extra minutes to the cooking time. For larger, shell-on prawns, it is generally better to thaw them first. Thawing allows for more even cooking and a better final texture. The quickest way to thaw is to place them in a colander under cold running water.
3. How do I really know what size prawns I'm getting? Always look for the count per kg or lb on the packaging (e.g., 26/30, 40/50). This is the most reliable indicator of size. Remember, the smaller the numbers, the larger the prawns. Ignore ambiguous marketing terms like "Jumbo" and rely on the count to make an informed choice.
