Save It I first tasted chili crab at a hawker center in Singapore during a humid evening, watching the cook crack shells with bare hands while sauce splattered everywhere. The sweet tang hit first, then the heat crept in, and I couldn't stop licking my fingers despite the mess. That night I promised myself I'd recreate it at home, even if it meant turning my kitchen into a seafood battlefield. It took three tries to get the sauce balance right, but now it's the dish I make when I want to feel that same thrill of discovery all over again.
I once made this for friends who'd never eaten crab with their hands before, and watching them navigate the shells with chopsticks was both charming and hilarious. By the end of the night, everyone had sauce on their sleeves and wide grins on their faces. We soaked up every last drop with fluffy mantou buns, and someone declared it the best dinner party they'd ever attended.
Ingredients
- Whole live mud crabs: Fresh crab makes all the difference here, the meat stays sweet and tender when cooked in the shell, and the shells infuse the sauce with deep seafood flavor.
- Vegetable oil: A neutral oil lets the aromatics and sauce shine without competing flavors.
- Onion: Chopped fine, it melts into the base and adds a subtle sweetness that balances the heat.
- Garlic and ginger: These two create the aromatic backbone, filling your kitchen with that unmistakable wok hei fragrance.
- Red chilies and birds eye chilies: Red chilies bring color and mild heat, while birds eye chilies pack the punch, adjust based on your tolerance.
- Tomato ketchup: It sounds simple, but it's the secret to that glossy, tangy sweetness that defines the sauce.
- Chili sauce: I use sambal oelek for a rougher texture and more complex heat than plain Sriracha.
- Sugar, soy sauce, and fish sauce: This trio balances sweet, salty, and umami, rounding out the bold tomato and chili base.
- Chicken or seafood stock: It thins the sauce just enough to coat the crab without being too thick or sticky.
- Cornstarch slurry: A quick stir at the end gives the sauce body so it clings to every piece of crab.
- Eggs: Beaten and drizzled in, they form those silky ribbons that soften the heat and add richness.
- Spring onions, cilantro, and lime: Fresh garnishes that brighten the whole dish and cut through the richness with a burst of green and citrus.
Instructions
- Start the aromatics:
- Heat the oil in your wok until it shimmers, then add the onion and let it soften without browning. The smell alone will make you hungry.
- Build the flavor base:
- Toss in the garlic, ginger, and both types of chilies, stirring constantly so nothing burns. The fragrance will bloom and fill the room within seconds.
- Sear the crab:
- Add the crab pieces and toss them hard in the wok, coating them in all those aromatics. You'll see the shells start to blush red, that's when you know they're ready for the sauce.
- Pour in the sauce:
- Add the ketchup, chili sauce, sugar, soy sauce, fish sauce, and stock all at once, stirring to coat every piece. The sauce will bubble up and turn a vibrant orange red.
- Simmer until cooked:
- Lower the heat and let the crab simmer, turning the pieces every few minutes so they cook evenly. The shells will deepen in color and the meat will turn opaque and sweet.
- Thicken the sauce:
- Stir in the cornstarch slurry and watch the sauce go from loose to glossy and clingy. Don't skip this step or the sauce will slide right off the shells.
- Add the egg ribbons:
- Drizzle the beaten eggs slowly into the bubbling sauce, stirring gently so they form soft, silky ribbons instead of scrambling. This is the magic moment that transforms the dish.
- Garnish and serve:
- Pull the wok off the heat, scatter the spring onions and cilantro over the top, and serve with lime wedges on the side. Eat it hot, messy, and with your hands.
Save It The first time I nailed this recipe, I sat alone at my kitchen table with a bowl of rice and a pile of crab shells, and I felt absurdly proud. It wasn't just about the flavor, it was about capturing a memory and bringing it home, one messy, delicious bite at a time.
Choosing Your Crab
Mud crabs are traditional and have rich, sweet meat, but if you can't find them, blue swimmer or Dungeness crabs work beautifully. Look for crabs that feel heavy for their size, that's a sign the meat is full and fresh. If you're squeamish about handling live crabs, ask your fishmonger to clean and portion them for you, no shame in that.
Adjusting the Heat
The birds eye chilies bring serious fire, so start with fewer if you're cautious and taste as you go. I like to keep a few deseeded red chilies on the side and stir them in at the end if I want more color without more burn. The eggs and sugar both help temper the heat, so don't skip either if you want a balanced dish.
Serving Suggestions
Steamed mantou buns are the classic pairing, their soft, pillowy texture soaks up the sauce like a dream. If you can't find mantou, crusty bread or jasmine rice work just as well, though you'll miss that fun of tearing and dipping. Set out finger bowls with warm water and lemon slices, and have plenty of napkins ready because this dish is gloriously hands on.
- Serve with a cold beer or iced lime juice to cut the richness.
- Have crab crackers and picks at the table so everyone can dig in properly.
- Leftovers reheat well, just add a splash of stock to loosen the sauce.
