A well-stocked freezer is a secret weapon for any home cook, and nothing offers more versatility than a bag of quality frozen prawns. They can transform a simple pasta dish, add a touch of luxury to a weeknight stir-fry or become the star of a weekend barbecue. However, when you set out to buy prawns online, the sheer number of options can be confusing.
Navigating the world of frozen seafood often means deciphering packaging codes and avoiding common purchasing traps that leave you with less than you paid for. Before you add a pack to your basket, it helps to be aware of a few pitfalls that can affect both the quality and value of your purchase.
To ensure you get exactly what you need for your kitchen, focus on these three key factors. Understanding them will help you select the right product every time, whether you're making a quick curry or an impressive seafood platter.

We have compiled a complete, real-time list of products that fully satisfy these strict selection criteria and UK safety regulations.
1. How should I defrost frozen prawns safely? The recommended method is to place the frozen prawns in a covered bowl in the refrigerator overnight. This gradual thawing helps maintain their texture. For a quicker method, you can place the required amount of prawns in a colander and run them under cold water until thawed, which should only take a few minutes. Never defrost prawns at room temperature or in warm water, as this can encourage bacterial growth.
2. Can I cook prawns from frozen? Yes, you can cook many types of prawns directly from frozen, which is particularly useful for dishes like soups, curries or paella where they will be boiled or simmered. Simply add them to your dish towards the end of the cooking time. They will only need a few minutes to cook through. For methods like pan-frying or grilling, it is generally better to thaw them first to ensure they cook evenly and don't release too much water into the pan. Always check the product's packaging for specific instructions.
3. What does the glaze percentage on a pack of frozen prawns mean? The glaze is a thin layer of ice applied to each prawn to protect it from freezer burn and preserve its quality. The glaze percentage tells you how much of the product's total weight is this protective ice. For example, a 1kg bag with a 20% glaze contains 800g of prawns and 200g of ice. It's an important detail to check, as a very high glaze percentage means you are getting less prawn for your money. Look for the net weight or drained weight for the true weight of the seafood.
