Grilled Beef Ribs with Trinidad Moruga Nam Jim Jeaw
Charcoal-grilled beef short ribs meet the fierce heat of Trinidad Moruga Scorpion peppers in this boundary-pushing take on Thailand's beloved nam jim jeaw—a smoky, tangy dipping sauce that transforms simple grilled meat into something unforgettable.
Beef short ribs meet the fire of Trinidad Moruga peppers in this extreme take on northeastern Thai grilled meat with nam jim jeaw dipping sauce.
Ingredients
For the Ribs
- 3 lbsbeef short ribs, cut flanken-style, 1-inch thick
- 2 tspkosher salt
For the Nam Jim Jeaw
- 4 wholeTrinidad Moruga Scorpion peppers, fresh, stems removed
- 6 wholedried Thai chilies, prik kee noo haeng
- 6 clovesgarlic, unpeeled
- 3 wholeshallots, unpeeled
- 3 tbspfish sauce
- 3 tbsplime juice, fresh
- 2 tsppalm sugar, or brown sugar
- 1 tbsptamarind paste
- 2 tbspglutinous rice, uncooked
Method
1. Toast Rice and Season Ribs Get a dry skillet going over medium heat and toss in the glutinous rice. Keep it moving and toast until it turns golden and starts smelling nutty—this takes about 5 minutes. Grind it up in your spice grinder to a coarse powder. While that's happening, give those ribs a good coating of salt and let them hang out at room temperature.
Watch for: Rice should smell nutty and turn light golden
2. Char Aromatics on the Grill Fire up your grill with one hot zone and one cooler spot. Toss the Trinidad Moruga peppers, dried chilies, garlic, and shallots (leave the skins on) right over the flames. Turn them now and then until they're properly blackened and give a little when you press them. The shallots and garlic take the longest to get tender inside.
Watch for: Everything should look charred outside but feel soft when pressed
Tip: Seriously, use tongs for those peppers—your skin will thank you later
3. Make the Nam Jim Jeaw Peel those charred garlic cloves and shallots once they're cool enough to handle. Now comes the fun part—grab your mortar and pestle and start with the peppers and dried chilies, pounding them down first. Add the garlic and shallots, then work in the fish sauce, lime juice, palm sugar, tamarind paste, and that toasted rice powder. You want it chunky and loose, not smooth.
Watch for: The sauce should coat a spoon but still be loose enough to drip
Tip: Go easy when you taste this—it packs a serious punch
4. Grill the Ribs Get those ribs over the hot zone and let them char up nicely, about 3-4 minutes per side. Once they've got good color, move them to the cooler side and start painting them with the nam jim jeaw every few minutes. You'll know they're ready when the meat starts pulling back from the edges of the bones.
Watch for: Aim for about 135°F inside if you've got a thermometer handy
Equipment
- Charcoal or gas grill
- Large mortar and pestle
- Spice grinder
- Tongs
- Instant-read thermometer
Make ahead
- The nam jim jeaw actually gets better after sitting for an hour—all those flavors meld together beautifully. You can make it up to 2 days ahead and keep it covered in the fridge. Just bring it back to room temperature before serving.
Storage
- Those leftover ribs will keep in the fridge for 3 days, and the sauce stays good for about a week. Store them separately though—the used sauce doesn't keep as well.
Reheat
- Wrap leftover ribs in foil and warm them in a 350°F oven, or give them a quick kiss on the grill again. Always serve with fresh sauce rather than reheating the used stuff.
Top tips
- Keep half that nam jim jeaw at the table—people will want to add more as they eat
- Flanken-cut ribs are your friend here—they cook faster and are perfect for this style of grilling
- Have some milk or coconut water ready to go. This isn't a joke-level heat
Substitutions
- Carolina Reapers or 7-pot peppers hit the same heat level if you can't find Trinidad Moruga
- Regular jasmine rice works fine if you don't have glutinous rice lying around
- Brown sugar does the job perfectly well instead of palm sugar
Serve with
- Sticky rice is non-negotiable—you'll need something to cool down your mouth
- Those butter lettuce leaves make perfect little wraps for the meat
- A crisp Thai-style papaya salad on the side cuts through all that richness beautifully

Why this recipe works
Editorial notes before you cook
There's something magical about nam jim jeaw, the fiery northeastern Thai sauce that turns any grilled meat into a celebration. This version takes that magic and cranks it way up, swapping in Trinidad Moruga Scorpion peppers alongside the traditional dried chilies. Yes, it's much hotter than what you'll find at your local Thai spot, but it keeps everything that makes the original so addictive—that perfect balance of smoke, salt, and bright acidity. The beef ribs get nothing more than salt and fire, letting the sauce do all the talking. Just make sure you have some sticky rice and cold drinks within reach.
The goal here is not just heat. It is contrast, pacing, and texture: enough richness to feel satisfying, enough brightness to keep the plate moving, and enough chile character that the spice actually tastes like something.

FAQ
The repeat questions
How hot is this compared to restaurant Thai food?
Think of your spiciest restaurant Thai dish, then multiply that by about 20. Trinidad Moruga peppers clock in around 2 million Scoville units, while most restaurant food tops out around 100,000. This is for serious heat lovers only.
Can I make this with milder peppers?
You absolutely can, but you'll be missing the whole point of this recipe. If you want to dial it back, try habaneros or bird's eye chilies—still hot, but much more manageable.
What if I don't have a mortar and pestle?
A food processor can pinch-hit, but pulse it carefully. You want to keep that chunky texture that makes nam jim jeaw what it is—don't turn it into baby food.
