Thai pork and tomato dipping sauce
This Northern Thai dip or nam phrik ong is one of my absolute favorite relishes! It’s like a Thai-style bolognese with minced pork, ripe tomatoes, and the heat of spicy chilies.

Making a Thai pork and tomato chili dip is done with a traditional mortar and pestle. We’ll mash the ingredients into a sauce, just like how we prepare Thai red curry paste.
This nam prik ong recipe begins with preparing a bold red chili paste, blending dried chilies, shallots, garlic, and shrimp paste. It’s the heart of this dish that gets mixed with juicy ground pork and lots of Thai seasonings.

Once the grilled tomatoes jump in, the sauce turns into a rich Thai pork and tomato dip that’s perfect for the whole family.
As for flavors, expect a balanced blend of spiciness, saltiness, with subtle hints of sweetness and tanginess.

Cooking instructions
-
Start by halving the large dried chilies and soak them in room temperature water with 2 teaspoons of salt. Allow them to soften for about 30 minutes. Drain them afterward to ease the pounding process.
-
Use a granite mortar and pestle to pound the soaked chilies, shallots, garlic, and shrimp paste into a smooth, fine paste.
-
1: Cook the paste. Heat oil in a large non-stick wok pan or skillet over medium heat. Add the freshly made paste and fry for approx 1 minute, until fragrant.
2: Add minced pork. Stir and cook until the meat is thoroughly cooked, about 1–2 minutes.
3: Add seasonings. Blend in tamarind paste, fish sauce, salt, palm sugar, and tomatoes. Cook until palm sugar has completely dissolved, and the tomatoes are tender, about 10 minutes. Stir regularly.
4: Pour in water. Let it simmer for 1 more minute. Serve hot.
