📝 About This Recipe

Born in the high-end kitchens of 1980s Hong Kong, XO Sauce is the pinnacle of Chinese condiments, named after premium XO cognac to denote its luxury status. This 'sea-savory' oil is a concentrated explosion of flavor, blending the intense sweetness of dried scallops and shrimp with the funk of cured ham and a slow-burning chili heat. It is a labor of love that transforms even the simplest bowl of noodles or steamed vegetables into a five-star gastronomic experience.

🥗 Ingredients

The Seafood Core

  • 150 grams Dried Scallops (Conpoy) (soaked in warm water for 2 hours or overnight)
  • 100 grams Dried Shrimp (soaked in warm water for 1 hour)
  • 100 grams Jinhua Ham or Prosciutto (finely minced)

Aromatics & Heat

  • 200 grams Shallots (peeled and finely minced)
  • 100 grams Garlic (peeled and finely minced)
  • 4-5 pieces Fresh Red Chilies (Thai bird's eye or Fresno, finely chopped)
  • 2-3 tablespoons Dried Chili Flakes (adjust to preferred heat level)
  • 2 tablespoons Fresh Ginger (finely grated)

The Liquid Gold & Seasoning

  • 2.5 cups Neutral Oil (Grapeseed, canola, or peanut oil)
  • 3 tablespoons Oyster Sauce (premium quality preferred)
  • 2 tablespoons Shaoxing Rice Wine (for deglazing)
  • 1 tablespoon Dark Soy Sauce (primarily for deep mahogany color)
  • 1 tablespoon Brown Sugar (to balance the saltiness)
  • 1 teaspoon Chicken Powder or MSG (optional, for authentic restaurant depth)

👨‍🍳 Instructions

  1. 1

    Drain the soaked scallops, reserving the soaking liquid. Steam the scallops for 15-20 minutes until very tender, then use your fingers or a fork to shred them into fine, hair-like fibers.

  2. 2

    Drain the dried shrimp and pulse them in a food processor until they reach a coarse, sandy texture. Do not over-process into a paste.

  3. 3

    Finely mince the Jinhua ham or prosciutto. If the ham is very hard, you may steam it for 10 minutes before mincing to soften it.

  4. 4

    In a large heavy-bottomed wok or Dutch oven, heat the 2.5 cups of oil over medium-low heat. The oil should be shimmering but not smoking.

  5. 5

    Add the shredded scallops to the oil. Fry gently, stirring constantly, for about 10-15 minutes until they turn golden brown and crispy. This step develops the base flavor.

  6. 6

    Add the minced shrimp and ham to the wok. Continue to fry for another 10 minutes. The mixture will foam slightly; this is normal as moisture evaporates.

  7. 7

    Stir in the minced shallots. Cook for 5-8 minutes until they become translucent and start to turn golden.

  8. 8

    Add the garlic, ginger, and fresh chilies. Fry for another 5 minutes until the aromatics are fragrant and the garlic is pale gold. Be careful not to burn the garlic.

  9. 9

    Add the dried chili flakes and stir well to infuse the oil with a vibrant red hue.

  10. 10

    Pour in the Shaoxing wine to deglaze, followed by the oyster sauce, dark soy sauce, brown sugar, and chicken powder. Add 2-3 tablespoons of the reserved scallop soaking liquid for extra depth.

  11. 11

    Reduce the heat to the lowest setting and simmer the mixture for 15-20 minutes. The sauce is ready when the oil has separated from the solids and the color is a deep, dark mahogany.

  12. 12

    Remove from heat and let the sauce cool completely in the pan. The flavors will continue to meld as it cools.

  13. 13

    Transfer the sauce and all its oil into sterilized glass jars. Ensure the solids are completely submerged under the oil to preserve freshness.

💡 Chef's Tips

Patience is key; never rush the frying process or use high heat, as burnt garlic or shallots will turn the entire batch bitter. Always shred the scallops by hand or fork rather than a blender to maintain the signature 'stringy' texture of authentic XO sauce. If you can't find Jinhua ham, a high-quality dry-cured Prosciutto or Smithfield ham is an excellent substitute. For the best flavor, let the sauce mature in the refrigerator for at least 3 days before using; it only gets better with time. Ensure your jars are bone-dry before filling; any water introduced to the oil can cause spoilage.

🍽️ Serving Suggestions

Toss two tablespoons into a simple bowl of al dente egg noodles with a splash of black vinegar. Use it as a premium topping for steamed scallops on the half-shell or grilled king prawns. Stir-fry with snap peas, asparagus, or bok choy for an instant side dish upgrade. Serve alongside a dim sum spread as a dipping sauce for turnip cakes or har gow (shrimp dumplings). Fold a spoonful into your morning fried rice or over a soft-boiled egg on toast.
