What is Nigerian Crayfish?

In Nigerian cooking, "crayfish" refers to small dried freshwater shrimp that have been sun-dried and ground into a coarse powder. Despite the name, Nigerian crayfish are actually shrimp (Macrobrachium species and others), not the freshwater crayfish (crawfish) of American cuisine. The confusion arises from the West African English usage of "crayfish" to mean any small crustacean.

Ground crayfish is one of the most important flavour ingredients in Nigerian cooking. It is added to virtually every Nigerian soup — egusi, ogbono, oha, bitter leaf, pepper soup, banga — as well as stews, rice dishes, and bean dishes. Its function is to add a deep, concentrated umami flavour that elevates the entire dish. Without crayfish, Nigerian soups taste flat and one-dimensional.

The flavour of Nigerian crayfish is intense and distinctive — deeply savoury with a strong seafood character, similar to shrimp paste or fish sauce but in dry form. A small amount (1-2 teaspoons) is enough to transform an entire pot of soup. It is not meant to taste "fishy" in the finished dish — it should blend into the background as a flavour enhancer, not a primary flavour.

Types of Nigerian Crayfish

Ground Crayfish (Most Common)

Dried shrimp ground to a coarse or fine powder. The most convenient form for cooking — simply scoop and add. AfroSpice stocks ground crayfish in various sizes.

Whole Dried Crayfish

Whole dried shrimp, not ground. Can be ground at home in a blender or spice grinder. Some cooks prefer whole crayfish for certain dishes as the texture adds interest.

Smoked Crayfish

Dried shrimp that have been smoked before drying. Has a more complex, smoky flavour. Used in some regional Nigerian dishes.

How to Use Crayfish in Nigerian Cooking

Dish Amount When to Add
Egusi Soup 2-3 tsp With the egusi
Ogbono Soup 2 tsp With the stock
Pepper Soup 1-2 tsp With the spices
Oha Soup 2 tsp With the stock
Nigerian Beans 1 tsp During cooking

Frequently Asked Questions

Can I substitute crayfish with something else?

The closest substitutes are shrimp paste (use 1/4 the quantity — it is much more concentrated), dried shrimp from Asian supermarkets (similar but slightly different flavour), or fish sauce (use sparingly). None are perfect substitutes — Nigerian crayfish has a unique flavour profile. AfroSpice delivers authentic Nigerian crayfish to all UK addresses.

How should I store ground crayfish?

Store in an airtight container in a cool, dry place. Ground crayfish keeps for 3-6 months at room temperature and up to 1 year in the freezer. The strong smell is normal — it does not indicate spoilage. Spoiled crayfish will smell rancid (like old cooking oil) rather than just strongly fishy.

Is Nigerian crayfish the same as Chinese dried shrimp?

They are similar products — both are dried shrimp — but they are not identical. Nigerian crayfish tends to be smaller shrimp with a slightly different flavour profile. Chinese dried shrimp can be used as a substitute but the flavour will be slightly different. For authentic Nigerian dishes, Nigerian crayfish is preferred.
