Kaeng Phet Pet Yang

Central Thai·Medium·25 min active + 5 min resting

Red curry of sliced Cantonese-style roast duck simmered in coconut milk with lychee, pineapple, cherry tomato, and Thai basil — fruit is the signature.

Kaeng Phet Pet Yang is a Bangkok-Chinese-Thai hybrid that became standard in central Thai restaurants in the mid-20th century. The duck is almost always Cantonese roast duck from a Chinatown shophouse — the crisp-skin Thai-Chinese pet yang lineage descends from Teochew migrants. Adding fruit (lychee, longan, pineapple, grape) to red curry is a Bangkok refinement; older central Thai red curry uses bamboo shoot or eggplant. The fruit version became a hotel-restaurant favourite for Western diners in the 1970s onward.

A Bangkok-Chinese hybrid built on Cantonese roast duck from Chinatown shophouses — the pet yang lineage descends from Teochew migrants. Fruit (lychee, pineapple, tomato) goes in for the last 3 minutes only; longer and lychee turns fibrous, tomato disintegrates. Skip the taek man stage and the curry tastes thin.

Coral-red curry with a slick of orange coconut oil floating on top. The duck is two-textured — crisp-skin remnants softened by the broth, the meat absorbing curry like a sponge. Then the fruit hits: sweet lychee burst, sour pineapple, tomato pop. Heat is medium, balanced by palm-sugar sweetness and fruit. If the fruit is mushy or the curry tastes flat-sweet without crack-cream gloss, the cook skipped the taek man stage.

Two technique points: first, 'taek man' — the thick coconut cream must be reduced until oil splits before the paste goes in, so the paste fries in coconut oil rather than boils in water. Without this the curry tastes thin and the spice never blooms. Second, the fruit goes in last for 3 minutes only — lychee and pineapple turn fibrous and tomato disintegrates if simmered with the duck. Roast duck is added pre-cooked; you are warming it, not cooking it.

Variations

Bangkok hotel restaurants from the 1970s onward run lychee-and-tomato; Chiang Mai cooks add longan; Phuket houses sub in mangosteen and pineapple; Nahm (Bangkok) plates a David Thompson version using bamboo shoot instead of fruit; older Central Thai red curry with duck used only eggplant.

How it's made

6 steps · 25 min active + 5 min waiting

  1. 1
    8 min

    Quarter 500g pre-roasted duck (Cantonese-style char siu duck or Thai pet yang) along the bone, then slice meat off into 1cm-thick pieces; reserve any duck skin.

  2. 2
    5 min

    Crack 400ml thick coconut cream into a wok over medium-high heat. Stir until the coconut oil splits out and the cream reduces to a glossy paste — about 5 minutes. This is the 'taek man' stage.

    Watch out

    Reduce the thick coconut cream until you see the oil break out and it turns glossy — the paste has to fry in that oil, not boil in liquid, or the spice never blooms.

  3. 3
    2 min

    Add 4 tbsp red curry paste (kaeng phet) and fry in the split coconut oil for 2 minutes until the paste darkens and smells of toasted spice and shrimp paste.

    Watch out

    Fry the paste in the split oil until it darkens and smells toasty of shrimp paste — that shift from raw-red to deep is the flavor turning on.

  4. 4
    8 min

    Pour in 400ml coconut milk and 200ml chicken stock. Add the sliced duck, 6 torn kaffir lime leaves, 1 tbsp palm sugar, 2 tbsp fish sauce. Simmer 8 minutes — duck warms through and absorbs curry.

  5. 5
    3 min

    Add 12 peeled lychees, 100g pineapple chunks, 8 halved cherry tomatoes, 2 sliced red Thai chiles. Simmer 3 minutes — fruit must stay firm, not collapse.

    Watch out

    Give the fruit only three minutes — lychee and pineapple must stay firm and the tomato whole; simmer longer and they go stringy and collapse.

  6. 6
    2 min

    Off heat. Stir in a fistful of Thai basil (horapha — sweet basil, not krapao). Serve with jasmine rice; the curry surface should glisten with split coconut oil.
