Shrimp paste, also known by various names like belacan, kapi, terasi, and ngapi, is a fermented condiment made primarily from ground shrimp or krill, salt, and sometimes other ingredients. It’s a staple in many Southeast Asian cuisines, adding a distinctive pungent aroma and a savory, umami-rich flavor to dishes. While its smell can be off-putting to some, its unique taste is highly prized by those who appreciate its complexity.
The Foundation: Shrimp and Krill
The primary ingredient in shrimp paste is, unsurprisingly, shrimp or krill. The type of shrimp or krill used can vary depending on the region and the specific type of shrimp paste being produced.
Different Species Used
In some areas, small shrimp species are preferred due to their abundance and affordability. These smaller shrimp are often readily available in coastal regions and can be easily processed into shrimp paste. In other regions, krill, tiny crustacean resembling shrimp, are the primary ingredient. Krill are particularly popular in regions where they are abundant, such as parts of Southeast Asia and Scandinavia (for similar fermented products).
The specific species used directly influence the final flavor and texture of the shrimp paste. Some shrimp varieties impart a sweeter, milder flavor, while others contribute a more intense, pungent taste. The size of the shrimp also plays a role, with larger shrimp sometimes requiring more processing and fermentation time.
Quality Considerations
The quality of the shrimp or krill is also crucial. Freshly caught shrimp or krill will yield a better quality shrimp paste with a more desirable flavor profile. Spoiled or improperly handled shrimp can lead to a lower quality product with an unpleasant taste and odor. Manufacturers take great care in selecting and processing their raw materials to ensure the best possible outcome.
The Preservative: Salt’s Crucial Role
Salt is the second most important ingredient in shrimp paste. It acts as a preservative, inhibiting the growth of undesirable bacteria and promoting the growth of beneficial microorganisms that contribute to the fermentation process.
The Science Behind Salting
The high salt concentration draws moisture out of the shrimp, creating an environment where spoilage bacteria struggle to survive. At the same time, the salt promotes the growth of halophilic (salt-loving) bacteria, which play a key role in the fermentation process. These bacteria break down proteins and other organic compounds in the shrimp, producing the characteristic flavors and aromas of shrimp paste.
Variations in Salt Content
The amount of salt used can vary depending on the recipe and the desired shelf life of the shrimp paste. Generally, a higher salt content will result in a longer shelf life, but it can also affect the final taste of the product. Some manufacturers prefer to use less salt to create a more subtly flavored shrimp paste, while others opt for a higher salt content to ensure a longer shelf life and a more intense flavor.
Other Ingredients: Adding Complexity
While shrimp and salt are the main ingredients, some recipes may include other ingredients to enhance the flavor, color, or texture of the shrimp paste.
Spices and Herbs
Some producers add spices and herbs like chilies, garlic, or peppercorns to their shrimp paste. These additions can impart a unique flavor profile, adding warmth, spiciness, or aromatic notes to the condiment. The choice of spices and herbs is often dictated by regional traditions and local preferences.
Rice Flour or Bran
In some variations, rice flour or bran may be added as a bulking agent or to adjust the texture of the shrimp paste. These ingredients can also contribute to the fermentation process, providing additional carbohydrates for the microorganisms to break down.
Food Coloring
In some commercially produced shrimp paste, artificial food coloring may be added to enhance its appearance. This is often done to create a more appealing color for consumers, but it can also be used to standardize the color of the product across different batches.
The Fermentation Process: The Magic of Transformation
The fermentation process is the heart and soul of shrimp paste production. It’s a complex biochemical process that transforms the raw ingredients into the pungent, umami-rich condiment that is so highly prized.
Traditional Methods
Traditionally, shrimp paste is made by mixing the shrimp or krill with salt and then allowing the mixture to ferment in the sun. The mixture is typically spread out on mats or trays and left to dry and ferment for several days or weeks, depending on the weather conditions and the desired flavor.
During this time, the shrimp undergoes a series of complex biochemical changes. Enzymes break down proteins and other organic compounds, releasing amino acids and other flavor compounds. Beneficial bacteria multiply and contribute to the fermentation process, producing the characteristic flavors and aromas of shrimp paste.
Modern Techniques
While traditional methods are still used in some areas, modern techniques are also employed in commercial production. These techniques may involve the use of controlled fermentation chambers, which allow for more precise control over the temperature and humidity. This can lead to a more consistent product with a shorter fermentation time.
Regional Variations: A World of Shrimp Paste
Shrimp paste is a diverse condiment with many regional variations. Each variation has its own unique flavor profile, texture, and production method.
Belacan (Malaysia)
Belacan is a Malaysian shrimp paste that is typically made from small shrimp or krill. It is known for its strong, pungent aroma and its savory, umami flavor. Belacan is often used as an ingredient in curries, sauces, and sambals.
Belacan is usually sold in dried blocks that are roasted or grilled before being used in cooking. This process helps to intensify the flavor and aroma of the shrimp paste.
Kapi (Thailand)
Kapi is a Thai shrimp paste that is typically made from fermented shrimp or krill. It is an essential ingredient in many Thai dishes, including green curry and nam phrik (chili paste).
Thai shrimp paste can vary in color from light pink to dark brown, depending on the type of shrimp used and the length of the fermentation process.
Terasi (Indonesia)
Terasi is an Indonesian shrimp paste that is made from fermented ground shrimp or krill, and salt. Often sold in dried block form, terasi has a powerful, pungent smell. It is an essential ingredient in many Indonesian dishes, such as sambal terasi, a spicy chili paste.
Ngapi (Myanmar)
Ngapi is a Burmese fermented condiment made from fish or shrimp. Various types exist, and those made from shrimp are used similarly to other shrimp pastes throughout Southeast Asia. It is a crucial ingredient in many Burmese dishes and is often served as a side dish or dipping sauce.
Uses in Cooking: Enhancing Flavors
Shrimp paste is a versatile ingredient that can be used in a variety of dishes to add depth of flavor and umami richness.
As a Base for Sauces and Dips
It is a common ingredient in sauces and dips, providing a savory base that complements other flavors. It is often used in conjunction with chilies, garlic, and other spices to create complex and flavorful sauces.
