So, a while ago, I found myself watching Mark Wiens’ extremely popular video about lang saeb AGAIN. In the video, he conquers a huge mountain of pork bones loaded with chilies. And all that was going through my mind was: I HAVE to try making my own laeng saeb recipe (เล้งแซ่บ)!

You know you’ve got to try something when you see Mark Wiens putting his stamp of approval on it, right?!

If you’re ever in Bangkok, definitely swing by the night market ‘Talad Rot Fai’.

“The market is known for its unique Thai street food, some of the snacks and dishes which are invented there, and you won’t find anywhere else in Bangkok.

Absolutely a top 3 bucket list place for me!

So, I heard about this dish a while ago, but never had the chance to taste or cook it myself. It’s kinda new, apparently popping up just a few years ago. That’s what I love about Thai food – it’s so diverse and surprising.

Trying leng saap for the first time was like a dream.

The broth? Packed with flavor from fresh lime juice and fiery chilies.

It’s rich, it’s porky, and it’s gonna have you slurping till the last drop!

And the meat? So tender, it just falls off the bones. Absolute perfection.

Believe it or not, it was pretty easy to make. The real challenge was stacking that mountain of meat, haha!

4 Reasons to try this recipe

• Spicy soup with pork bone. The liquid is packed with herbs and so many chilies. Each spoonful is bold, spicy, and can’t stop eating good.

What type of pork bone to use for soup

The best pork bones for soup are pork neck bones and pork back bones. They’ve got a perfect balance of meat, marrow, and bone, to give you a broth that’s rich and full of flavor.

• Back and spine bones: Rich in marrow, which enriches broths with flavor and nutrients.
• Neck Bones: Ideal for their marbling and flavorful meat.

Alternatively, you can use other cuts, like baby back ribs or (chopped) spare ribs. They’re packed with meat, so you’ll definitely have lots of that fall-off-the-bone goodness.

However, they’ll not add the same depth of flavor to the stock as the traditional choices of pork neck and back bones would.

For the best flavor, stick to the traditional leng bones.

Ingredients

For the exact measurements, please scroll down to the recipe card at the end of this post.

Pork stock

• Pork bones – The bones are simmered slowly so the marrow and meat impart their flavors into the soup. Traditionally, we use pork neck bones or pork back bones.
• Water – With the right amount of water, all the flavors become well-balanced without overwhelming each other.
• Light soy sauce – Adds a savory flavor, enhancing the overall taste of the soup.
• Black peppercorns – Add a subtle, spicy kick, infusing the broth with a subtle heat and a pungent aroma.
• Coriander root – Coriander root brings earthy and citrusy tones.
• Garlic
• Onion
• Salt

Leng saeb broth

• Fish sauce – This staple of Thai cuisine adds umami and a salty flavor.
• Green onions – Brings freshness and a mild, sweet flavor.
• Culantro – Culantro is a stronger, and more pungent version of cilantro. If you can’t find culantro, use cilantro.
• Chilies – I used bird’s eye chilies or “prik kee noo”, these are very popular in Thai cuisine and other Southeast Asian cuisines. They’re incredibly spicy, feel free to sub with a mild type of chili.
• Lime – Adds freshness and a tangy flavor, feel free to use as much of fresh lime juice as you want.

How to make pork bone soup

Leng saeb pork spine recipe tips

• Use high-quality bones. Look for fresh, high-quality bones at grocery stores or local / Asian / Chinese butchers.
• Slow simmering is key. It allows the pork to become tender. It’s crucial that the pork falls-off-the-bone.
• Customize the heat. I used bird’s eye chilies. If you prefer a milder heat, you can use a less spicy chili or remove their seeds. Avoid using fewer chilies, as the chilies add their flavor as well.
• Taste test. Adjust the flavor of salt, spice, and sourness to your taste.

Kitchen tools

• Cutting board and chef’s knife
• Measuring spoons and cups
• Large pot for soup
• Mortar and pestle
• Ladle

How to serve

Traditionally, the bones are shaped into a tower and then topped with the broth and many fresh herbs. Pair with a bowl of steamed rice or sticky rice.

Tip: Use a spoon to scrape the meat off the bones, and mix it with the spicy, flavorful and chilies. So good!

How to store and reheat

Store the leftover pork bones and broth separately in an airtight container in your refrigerator. It’ll stay fresh for up to 3 days.

Reheating instructions: Reheat the broth in a pot over medium heat, add the bones, and cook until warm.
