Nam prik – Thai chili dips

Nam prik is the term for a collection of Thailand’s spicy chili dips, with lots of delicious variations, like nam prik ong and nam prik noom.

For Thai people, it’s not just a side sauce; we use chili sauces to turn every meal into a feast.

Each nam prik or (nam phrik) variation is a blend of traditional Thai ingredients like fresh and dried chilies, garlic, lime juice, pungent shrimp paste, and umami fish sauce.

Traditionally, they’re prepared with a granite mortar and pestle, a staple in every Thai kitchen. The recipes for nam prik kapi are usually passed down through generations, with many Thai households having their own version.

What is shrimp paste

Shrimp paste, a common ingredient in Southeast Asian cooking, is made by crushing shrimp or krill with salt. The mixture is then left to ferment for several weeks to months. Finally, it’s dried in the sun for a few days to enhance its flavor.

It’s the key ingredient in this spicy relish, called ‘kapi’ in Thai.

Shrimp paste brings a salty, umami flavor and a memorable aroma. It can be quite pungent if you’re not used to it – but once you are, adding a bit of it to your Thai food will make it taste amazing.

Kapi, or fermented shrimp paste, is the secret ingredient that makes our traditional curry pastes like Thai red curry paste and Thai green curry paste come to life with a rich, savory depth. It’s also commonly used in Southern Thai cooking.

Ingredients

Ingredients can be sourced at Asian grocery stores and Asian markets.
The exact measurements are in the recipe card at the end of this post.

• Shrimp paste – In Thai language, we say that this is ‘pa eek’, which translates to the key ingredient. You can source a high quality shrimp paste at Asian grocery stores and Asian markets.
• Palm sugar – This natural sweetener adds a rich sweet flavor with a subtle hint of caramel that’s distinct from white and brown sugar.
• Fish sauce – Use high quality fish sauce, like Megachef, for the best salty, umami-rich flavor. This traditional ingredient of Asian cuisine is made from fermented fish and salt.
• Fresh chili peppers – Authentic Thai shrimp paste chili sauce is fiery. If you’re not into spicy food, feel free to use less chilies or remove the seeds. For a spicy dip, use bird’s eye chilies.
• Pea eggplants – Pea eggplants (turkey berry) are the secret charm of this dip, there’s simply no substitute. If you can’t find them, you can simply omit them. They add a nice color contrast and crunch.
• Garlic – Who doesn’t love garlic? It’s the pungent addition that levels up the flavor in pretty much any Thai dish.
• Lime – Fresh lime juice is a non-negotiable. It adds a zesty / tangy flavor typical to Thai cuisine.

Cooking instructions

Kitchenware

• Measuring spoons and cups
• Granite mortar and pestle

For this nam prik kapi recipe, I suggest using a stone/granite mortar and pestle. This makes it easier to pound down the ingredients into a fine dipping sauce. Alternatively, you can use a food processor, but you’ll lose that authentic touch.

Thai shrimp paste chili dip tips

Use fresh ingredients and the right tools: I highly suggest making nam prik kapi with a granite mortar and pestle, and to use the freshest ingredients you can find.

Taste test: Before serving, make sure to do a taste-test. If it needs more saltiness, add more fish sauce. If it’s too spicy, try adding a bit more sugar.

How to eat Thai shrimp paste dip

• Start with your nam prik kapi in the middle of a big tray.
• Fry some mackerel fish until golden (about 3 minutes on each side). In Thailand, these are incredibly popular and often sold at street food markets.
• Add a bunch of fresh vegetables like cabbage, cucumber, Thai eggplants, yard long beans, broccoli, and carrots. You can go for raw or boiled – your choice!
• Make a Thai-style omelet like minced pork omelette or cha-om omelette or just boil some eggs.
• You can also add some street food options like kai tod and moo ping.
• Don’t forget the rice! Jasmine rice or Thai sticky rice helps balance the strong flavors of the dip.

There are endless possibilities, but what matters most is the people gathered around it, enjoying from the same dish and engaging in conversation. Family time!

Storing leftovers

This condiment remains fresh in your refrigerator for up to 1 week. Seal your bowl or sauce cup thoroughly with plastic wrapper, or transfer it into an airtight container. Afterward, you can choose to eat kapi sauce chilled, or let it come to room temperature.
