Preparation

  • Wash the Choy Sum thoroughly. Remove any hard or old parts from the root end.
  • Use a knife to peel the outer tough skin of the stems if necessary. This makes the inside more tender, but be careful not to overcook as they might lose their crunch.
  • Finely mince the garlic. If you have onions or shallots, chop some as well.

Prepare the Sauce Base

  • In a small bowl, mix 5g soy sauce, 5g oyster sauce, 3g sugar, and about 100ml (half a bowl) of water.
  • Note: Adding a little cornstarch can help the sauce cling to the vegetables better and gives a stronger flavor, though this is less traditional in some Cantonese styles.

Blanch the Vegetables

  • Bring a pot of 500ml water to a boil. Add 5g salt and 10g cooking oil to the water.
  • Place the stems of the Choy Sum into the boiling water first and blanch for about 1 minute until they turn deep green.
  • Immerse the whole Choy Sum into the water and blanch for another 1 minute until cooked through.
  • Remove from water, drain well, and arrange neatly on a serving plate.

Make the Sauce and Serve

  • In a small pan, heat some oil. Once hot (about 50% heat), add the minced garlic and onion/shallot (if using). Sauté until fragrant.
  • Pour in the prepared sauce mixture. Add chopped bird's eye chili and ginger strips if desired.
  • Bring to a simmer. Let it reduce slightly or boil for a few seconds.
  • Pour the hot sauce directly over the arranged Choy Sum. Do not use too much sauce, but ensure there is plenty of garlic.

Recipe Notes:

  • Choose fresh Choy Sum for the best texture and flavor.
  • Adding oil and salt to the blanching water helps keep the vegetables glossy and green.
  • Peeling the thick stems is a great tip for tenderizing older Choy Sum.
  • The sauce quantity is for reference; adjust salt and sugar to your taste.
  • This dish is best served immediately.
