Asian prawn crackers: how to choose the right size, flavour and ingredients

Asian prawn crackers are loved for their light texture, seafood notes and convenient formats. But not all products are suited to the same purpose. Some are ready to eat, while others need to be fried. Some contain a precise amount of prawn, whereas others rely mainly on flavouring or seasoning.

Before buying prawn crackers, shrimp crackers or prawn crackers, there are three pitfalls that are particularly easy to avoid.

Common pitfalls before buying

1. Confusing ready-to-eat crackers with fry-at-home crackers

The term "prawn crackers" can refer to two very different products:

  • Asian snack biscuits that are already puffed and ready to open;
  • dried, uncooked discs that expand in hot oil.

A pack of raw krupuk udang usually needs to be immersed in oil heated to between 160 and 190 °C, depending on the manufacturer's instructions. An incorrect temperature will result in crackers that are too hard or unevenly cooked. For the office, a journey or a quick snack on the go, it's better to choose a ready-to-eat product.

2. Relying solely on the picture or the word "prawn"

The presence of prawn may be indicated as a percentage, powder, extract or simply within the composition of a seasoning. These mentions are not all equal. Some products, for example, state 5.6 % or 6.2 % prawn, while others merely claim a crustacean flavour.

Take the time to read the ingredients list and the quantitative declaration, where available. This way, you can tell the difference between a recipe based on tapioca and prawn, and a simple flavoured potato crisp.

3. Overlooking allergens and the actual size

Crustaceans are among the allergens that must be declared by law. Depending on the recipe, the product may also contain wheat, soya, milk, mustard, sesame or sulphites. As the composition can vary by country and batch, always check the label on the pack you receive.

Weight also affects usage: a 40 to 80 g bag is suitable for a single portion, while a 200 g pack or a carton of several kilograms is aimed at sharing, parties or catering.

Criteria to check when choosing

Ready to eat or to prepare

For a snack with no preparation required, choose products clearly marked "ready to eat" or "prêts à consommer". Already fried or puffed crackers are perfect for students, work breaks or movie nights.

Uncooked versions offer more flexibility to accompany a curry, soup or salad. However, they require very hot oil and careful attention – the discs puff up in just a few seconds.

Recipe base and prawn percentage

Recipes based on tapioca starch generally produce a well-puffed, airy texture after frying. Wheat-based versions are more like crunchy sticks or biscuits. Look in particular at:

  • the flour or starch listed first;
  • the percentage of prawn, white prawn or crustacean powder;
  • the presence of oil, sugar, salt and flavour enhancers;
  • the spices used, such as chilli, garlic, onion or pepper.

Fans of spicy prawn crackers should check for red chilli, paprika or chilli oil rather than relying on the colour of the packet alone.

Nutritional values and storage

Compare the values per 100 g, not just those for the portion stated on the packaging. Puffed crackers are still snack products – depending on the recipe, they can be quite high in calories, fat or salt.

After opening, reseal ready-to-eat bags carefully. For uncooked crackers, store them in an airtight container away from moisture. Otherwise, they may not puff up as well and could lose their crunchy texture.

Frequently asked questions about Asian prawn crackers

Are prawn crackers always ready to eat?

No. Already puffed crackers, such as several Nongshim or Oishi products, can be eaten straight away. Uncooked versions, often sold in 200 g, 1 kg or 2 kg bags, need to be fried following the manufacturer's instructions.

How should I store prawn crackers after opening?

Keep them in a cool, dry place. Ready-to-eat products should be resealed carefully and consumed promptly. For uncooked discs, use an airtight container to protect them from moisture. Also remember to check the best-before date on the packaging.

What size should I choose for a party or restaurant?

For a few guests, an 80 to 200 g bag is usually enough. For regular or professional use, a 12 × 1 kg case allows you to build up a substantial stock, provided you have a dry storage space and suitable frying equipment.
