What Pad Priew Wan means

ผัดเปรี้ยวหวาน names the cooking method and the two flavours. Pad means stir-fry, priew means sour and wan means sweet. Pad Preaw Wan is another spelling of the same Thai name. T1 E2 E5

Pineapple adds sweetness and tang, cucumber keeps a little bite, and savoury seasonings give the sauce depth. Chef Thanakorn’s version uses chilli sauce and ground white pepper. The amount of heat you taste depends in part on the chilli sauce you choose. T1

Pholfoodmafia describes the dish as influenced by Chinese cooking. Its recipes illustrate several preparations, while the earliest version and its maker remain uncertain. In one example from the same publisher, Phol Tantasathien coats and fries pork before tossing it with a ketchup, plum sauce and vinegar mixture. Chef Thanakorn cooks his chicken directly in the wok and reduces its sauce before adding the vegetables. T1 T2 T3

For a Thai stir-fry built around aromatics, see Pad Kratiem, Thai garlic and pepper stir-fry.

Choosing pineapple, vegetables and seasonings

Cut the vegetables and pineapple before heating the wok. Remove the wet centre from the tomato and scoop some of the seed core out of the cucumber. The sauce has already reduced a little by the time the vegetables go in, so they need only a brief toss. T1

Ingredients and their roles
IngredientRoleWhat to look for
PineappleSweetness, tang and juicy bites.Cut fresh pineapple into bite-sized pieces, or drain tinned chunks in juice for an adaptation.
Cucumber and tomatoCucumber gives bite and tomato adds a softer, tangy contrast.Remove the watery centres before cooking.
Sweet peppers and onionColour and texture.Three pepper colours are used in the source. One colour works as a practical adaptation.
Ketchup and chilli sauceSweet and tangy seasoning, with heat from the chilli sauce.Check how sweet or hot the chilli sauce is.
Oyster sauce, light soy and seasoning sauceSavoury seasoning.Conventional oyster sauce contains molluscs. Check individual labels for soya, wheat and other allergens.
White pepper and spring onionsPepper warmth and a fresh finish.Add spring onions at the end.

The ingredient table describes Chef Thanakorn’s recipe. For a different sauce, use the measurements from the relevant vinegar or tamarind version. T1 E1 E2 U4

Thai sweet and sour chicken recipe

Adapted from Chef Thanakorn Ployseechomphu’s Thai-language Pholfoodmafia recipe. The source gives 150 g chicken and leaves the yield and timing unspecified. Use a 15 ml tablespoon and a 5 ml teaspoon. The probe check is a food safety addition. T1 U1

Ingredients

  • 2 tbsp rice bran oil and 1 tbsp pounded garlic
  • 150 g chicken breast, cut into even pieces
  • 4 tbsp water
  • 1½ tbsp oyster sauce
  • 1½ tsp light soy sauce and 1½ tsp Thai seasoning sauce
  • 1½ tbsp chilli sauce and 1½ tbsp tomato ketchup
  • Ground white pepper, to season
  • 70 g diced sweet peppers, using a mix of colours if available, and 40 g diced onion
  • 50 g diced, deseeded tomato and 40 g cucumber, cut into pieces with some of the seed core removed
  • 60 g pineapple, cut into bite-sized pieces
  • 2 spring onions, cut into short lengths

Method

  1. Prepare the vegetables. Cut the peppers, onion and pineapple. Scoop out the wet centre of the tomato and part of the cucumber core before cutting them. Slice the spring onions and measure the sauces.
  2. Cook the chicken. Stir-fry the garlic in the rice bran oil, then add the chicken. Cook it through before adding the measured water. Check the centre of a thick piece with a clean probe. One Food Standards Agency combination is 75°C held for 30 seconds. U1
  3. Season and reduce. Stir in the oyster sauce, light soy sauce, seasoning sauce, chilli sauce, ketchup and white pepper. Let the sauce bubble until it thickens slightly.
  4. Add the vegetables and pineapple. Toss the peppers, onion, tomato, cucumber and pineapple through the sauce briefly, keeping some bite in the vegetables.
  5. Finish with spring onions. Stir them in, take the pan off the heat and serve. Steamed jasmine rice is a serving suggestion.

Keep raw chicken and its utensils separate from prepared produce and cooked food. This version uses conventional oyster sauce and light soy sauce. Check the labels of all the prepared sauces for the needs of the people eating. U1 U4

Pholfoodmafia describes it as influenced by Chinese cooking. The cited recipes show how Thai cooks prepare it and leave its first maker and date open. T1 T2

6. How does it compare with Chinese-style sweet and sour pork?

The chicken here goes straight into the wok. In Phol Tantasathien’s Chinese-style pork recipe, the meat is coated and fried separately before it meets a ketchup, plum sauce and vinegar mixture. T1 T3

Taste and heat

7. What does Pad Priew Wan taste like?

Expect sweetness and tang from the fruit and sauce, with a savoury base. The chicken version here has some warmth from chilli sauce and ground white pepper. T1

8. Is Pad Priew Wan spicy?

It depends on the recipe and the chilli sauce. The main recipe includes chilli sauce. Suwanee’s rice-vinegar version gives you a separate option without that ingredient. T1 E1

9. Is the sauce thick?

In the main recipe it reduces just enough to coat the ingredients. Wandercooks uses a cornflour slurry for a thicker glaze. T1 E3

10. What makes it sweet?

Pineapple and the prepared sauces contribute sweetness in Chef Thanakorn’s version. Suwanee adds granulated sugar to her rice-vinegar dressing. T1 E1

11. What gives the dish its sourness?

It varies with the sauce. Pineapple, tomato and ketchup bring tang to the main recipe. Other versions use rice vinegar or tamarind purée. T1 E1 E2

12. Does it taste like sweet chilli sauce?

The overall flavour comes from the fruit, vegetables and savoury seasonings. Chef Thanakorn specifies chilli sauce and ketchup as two ingredients. T1

Sauce choices

13. Does Pad Priew Wan need tamarind?

Chef Thanakorn’s chicken recipe uses ketchup and chilli sauce. World of Thai Food uses tamarind purée in a separate pork version. T1 E2

14. Can I make it without ketchup?

Use a recipe built for that flavour. Suwanee’s version uses rice vinegar, sugar, oyster sauce, soy sauce and fish sauce. E1

15. Can I use tamarind instead of ketchup spoon for spoon?

Use the proportions of a tamarind recipe. Tamarind purée provides acidity, while ketchup contributes both tang and sweetness to Chef Thanakorn’s sauce. T1 E2

16. Does every version use fish sauce?

Fish sauce is part of the Suwanee and World of Thai Food recipes. Chef Thanakorn uses oyster sauce, light soy sauce and seasoning sauce. T1 E1 E2

17. Is Thai seasoning sauce the same as dark soy sauce?

The recipe lists seasoning sauce separately from light soy and gives no dark soy quantity. Buy a Thai seasoning sauce, then check its own label and strength. T1 U4

18. Should I mix the sauce in advance?

For the main recipe, you can measure the seasonings together before cooking and keep the water separate. Suwanee specifically mixes her own sauce in a bowl first. T1 E1

Pineapple and vegetables

19. Can I use tinned pineapple?

Yes. Choose chunks in juice and drain them for a home adaptation. Taste the sauce before adding juice, which adds both liquid and sweetness. E1 E4

20. When should the pineapple go into the pan?

Add it with the other vegetables in Chef Thanakorn’s version. Suwanee puts it in at the end with the spring onions. T1 E1

21. Can cucumber go into a hot stir-fry?

Yes. Brief cooking keeps some bite. Chef Thanakorn removes part of the seed core and cuts the cucumber into pieces before it goes in. T1

22. Why scoop out the tomato seeds?

It reduces the wet centre added to the pan. Chef Thanakorn uses deseeded tomato and cucumber in this recipe. T1

23. Can I use one colour of pepper?

Yes. Three colours are specified in the source for the mix. One sweet pepper colour is a straightforward home adaptation. T1

24. What part of the spring onion goes in?

Cut the spring onions into short lengths and add them last. They need only brief contact with the heat in the main recipe. T1

Wok method

25. Do I need a wok?

A roomy frying pan is a practical alternative. Use enough surface area for the chicken and vegetables to cook without piling up. E1

26. Is the chicken battered?

In this home recipe, sliced chicken cooks directly with the garlic and oil. A separately coated preparation has a different method and texture. T1 T3

27. What do I prepare before heating the pan?

Dice the fruit and vegetables, cut the spring onions and measure the sauces. Slice the chicken on a separate board and wash hands and equipment after handling it. T1 U1

28. When should I add the water?

Add it after the chicken is cooked through, then add the seasonings and reduce the sauce briefly. T1 U1

29. Should I fry the vegetables before adding the sauce?

In the main recipe the sauce goes in first. The vegetables and pineapple follow after it thickens slightly. T1

30. How do I check that the chicken is cooked?

Use a clean food thermometer in the centre of a thick piece. One Food Standards Agency combination is 75°C held for 30 seconds. U1

Protein and plant-based options

31. Can I use chicken thigh instead of breast?

Yes, as a home adaptation. Slice boneless thigh evenly and check the thickest pieces with a clean thermometer. T1 U1

32. Can I use pork?

Yes. Chef Thanakorn names pork as an option, and World of Thai Food publishes a pork tenderloin version with its own tamarind sauce. T1 E2

33. Can I use prawns?

Yes. Chef Thanakorn lists prawns as an alternative. Use a method appropriate to prawns and check crustacean allergy requirements separately. T1 U1

34. Can I use fish?

Yes. Fish is one of Chef Thanakorn’s suggested alternatives. Choose firm pieces and turn them gently so they stay intact. T1

35. Can I use tofu?

Firm tofu is an option for a home adaptation. Pat it dry and brown it separately if you want firmer edges. Check every sauce for animal ingredients if cooking vegan. T1 E5

36. Can I use vegetables as the main ingredient?

Yes. Thai Cookbook TV publishes a vegetable-led version with its own sauce. Check its oyster sauce before using it for a vegetarian meal. E5

Allergens and dietary questions

37. Does the main home recipe contain molluscs?

Yes. It uses conventional oyster sauce. Check the specific bottle and any alternatives against the allergy requirements of the person eating. T1

38. What should I check for a fish allergy?

Check fish sauce, prepared seasonings and any protein choices. Suwanee’s sauce contains fish sauce. At a restaurant, explain the allergy before ordering and ask about preparation. E1

39. Is Pad Priew Wan gluten-free?

Check the complete recipe. Soy sauce, seasoning sauce, oyster sauce and prepared sauces can differ by brand. For coeliac disease, check gluten-free labelling and how the food is prepared. T1 U4

40. Is tofu Pad Priew Wan vegan?

It can be if the sauces and complete preparation are suitable. Conventional oyster and fish sauces need suitable plant-based replacements where used. T1 E1

41. Is it suitable for a soya allergy?

The main recipe includes light soy sauce. Check the seasoning sauce and other prepared products too, and discuss preparation with the person cooking. T1

42. Can Charm Thai Cafe guarantee no allergen cross-contact?

The kitchen is shared and handles allergens. Tell the team about allergies or coeliac disease before ordering so they can discuss ingredients and preparation.

Serving and making ahead

43. What should I serve with it?

Plain jasmine rice is a good choice. It takes up the sauce and gives the sweet, sour and savoury flavours room to stand out. E1

44. How much chicken is in the home recipe?

The source specifies 150 g of chicken breast before cooking. It gives no serving count, so use the measured quantities when planning your meal. T1

45. Can I prepare the vegetables ahead?

Yes. Cut them and refrigerate them covered. Keep raw chicken separately in the fridge so its juices cannot drip onto produce or cooked food. U2

46. Can I double the recipe?

Yes. Scale the ingredients together and cook in batches if the pan is crowded. Bring each batch through the full cooking and temperature check. T1 U1

47. Should I serve it immediately?

Serve it when the vegetables are still firm and the sauce coats the chicken. A long hold in the hot pan softens cucumber and tomato. T1 E5

48. What if I want more heat at the table?

Offer fresh chilli separately or choose a hotter chilli sauce when cooking. Taste first, as prepared chilli sauces vary in sweetness as well as heat. T1 E2

Troubleshooting

49. Why is my stir-fry watery?

A crowded pan, undrained pineapple or wet vegetable centres can contribute extra liquid. Drain and prepare the produce, then let the sauce reduce slightly before the vegetables go in. T1

50. Why did the vegetables go soft?

They were probably in the pan too long. Cut them evenly and add them late so they heat through while keeping some bite. T1 E5

51. How can I adjust a sauce that tastes too sweet?

Taste it before adding the vegetables and make small changes. A few drops of rice vinegar can add tang to a home adaptation. Use a separate recipe if you want vinegar as the main souring ingredient. E1

52. How can I adjust a sauce that tastes too sharp?

Add a little water if the sauce is over-concentrated, then taste again. Suwanee’s version suggests a small touch of sugar as another final adjustment. E1 E4

53. How do I prevent dry chicken?

Slice it evenly, use a roomy pan and avoid extended cooking once the safety check is met. The sauce and vegetables need only brief cooking afterwards. T1 U1

54. How do I make a thicker coating?

Reduce the sauce a little before adding the vegetables. If you want a cornflour-thickened sauce, use the method and proportions in the Wandercooks version. T1 E3

Leftovers and ordering

55. How many calories are in Pad Priew Wan?

A figure depends on the recipe, cooked portion and whether you include rice. Use the weights and yield of the particular version if you want to calculate it.

56. How do I refrigerate the cooked stir-fry?

Divide it into smaller portions, cool and refrigerate within one to two hours. Keep the fridge at 0°C to 5°C and use the stir-fry within 48 hours or freeze it. U2

57. Can I freeze the stir-fry?

Yes. Freeze it promptly once cooled and defrost it in the fridge. Use it within 24 hours of fully defrosting. Cucumber and tomato may soften. U2

58. Can I reheat it?

Reheat the stir-fry only once, until steaming hot throughout. Stir partway through when microwaving so there are fewer cold spots. U1 U2

59. How should I store the rice separately?

Cool cooked rice as quickly as possible, ideally within an hour. Refrigerate it for no more than 24 hours before reheating once, until steaming hot throughout. U3
