Why I Love This Recipe

Singapore Chilli Crab is arguably the island nation's most iconic dish, created in the 1950s by Cher Yam Tian and her husband Lim Choon Ngee at their humble seafood stall. What started as an experiment with tomato sauce, chilli, and egg ribbons has become a national treasure that draws food lovers from around the world. This dish perfectly embodies Singapore's culinary philosophy - taking the best from different cultures and creating something uniquely local. The sauce strikes a perfect balance between sweet and spicy, with a glossy finish that coats every piece of succulent crab meat. While messy to eat, that's part of the charm - you'll need plenty of napkins and the iconic fried Chinese mantou buns to soak up every drop of that addictive sauce.

  • •National treasure status – Experience Singapore's most famous dish that represents the country's culinary identity

Ingredients You'll Need

Here's what you'll need – nothing too fancy, just good ingredients that work together beautifully.

  • 2 whole live mud crabs (about 600g each, or use frozen if unavailable)
  • 3 tablespoons vegetable oil
  • 6 cloves garlic (minced)
  • 2 cm piece ginger (minced)
  • 3 whole red chillies (sliced, adjust to taste)
  • 4 tablespoons tomato ketchup
  • 2 tablespoons chilli sauce (sweet chilli sauce preferred)
  • 2 tablespoons tomato sauce
  • 1 tablespoon rice vinegar
  • 2 tablespoons sugar
  • 1 tablespoon light soy sauce
  • 120 ml chicken stock
  • 1 tablespoon cornstarch (mixed with 2 tbsp water)
  • 2 whole eggs (lightly beaten)
  • 2 stalks spring onions (chopped)
  • 2 tablespoons coriander leaves (chopped)

Step-by-Step Instructions

  1. 1

    Prepare the crabs by cleaning them thoroughly under cold running water, scrubbing the shells with a brush. Remove the top shell, gills, and stomach sac. Cut each crab into 4-6 pieces, keeping the claws whole but cracking them slightly with the back of a cleaver. Pat completely dry with paper towels.

    ~10 min

    Tip: Dry crabs are crucial for proper searing
  2. 2

    Combine all sauce ingredients (ketchup through chicken stock) in a bowl and whisk until smooth. The mixture should be glossy and well combined. Set aside until needed.

    ~3 min

  3. 3

    Heat oil in a large wok or heavy-bottomed pan over high heat until shimmering. The oil should be very hot to achieve proper searing of the crab shells.

    ~2 min

    Tip: High heat is essential for the signature 'wok hei' flavour
  4. 4

    Add crab pieces to the hot oil and stir-fry vigorously for 3-4 minutes until the shells turn bright red and the meat is just cooked through. Work in batches if necessary to avoid overcrowding. Remove crabs and set aside temporarily.

    ~4 min

  5. 5

    In the same wok, reduce heat to medium-high and add minced garlic, ginger, and sliced chillies. Stir-fry for 30 seconds until fragrant, being careful not to burn the garlic.

    ~1 min

    Tip: Keep ingredients moving constantly to prevent burning
  6. 6

    Pour in the prepared sauce mixture and bring to a vigorous boil. The sauce should bubble actively and begin to thicken slightly after 2-3 minutes of cooking.

    ~3 min

  7. 7

    Return the crab pieces to the wok and toss vigorously to coat every piece with the sauce. Cook for 2-3 minutes, ensuring the sauce penetrates the crab shells and meat.

    ~3 min

  8. 8

    Stir the cornstarch slurry once more to recombine, then pour it into the wok while stirring constantly. This will give the sauce its signature glossy, clingy texture that coats the crab beautifully.

    ~1 min

    Tip: Add cornstarch gradually while stirring to prevent lumps
  9. 9

    Create egg ribbons by slowly drizzling the beaten eggs into the wok while stirring the contents with chopsticks or a fork. The eggs should form silky ribbons throughout the sauce rather than scrambling into chunks.

    ~2 min

  10. 10

    Remove from heat immediately and garnish with chopped spring onions and coriander leaves. Serve immediately while piping hot, with plenty of napkins and fried mantou buns on the side.

    ~1 min

How Do I Know It's Ready?

Crabs are done when shells turn bright red-orange and meat is opaque white throughout. The sauce should be glossy and coat the back of a spoon lightly. Egg ribbons should be silky and just set, not rubbery or overcooked.

Frequently Asked Questions

Yes, frozen mud crabs work well for this recipe, though the texture won't be quite as sweet and tender as live crabs. Thaw them completely in the refrigerator overnight, then pat them completely dry before cooking. You may need to reduce the initial stir-frying time by 1-2 minutes since frozen crab is partially pre-cooked.
