Sweet and Sour Pork is one of the most well known and well loved Chinese dishes among the Chinese and non-Chinese alike, with its winning combination of crispy pork bites and tangy sweet and sour sauce.
Wash the pork and cut into 3 cm cubes.
Marinate the pork with all the marinade ingredients, except for the cornflour, rice flour and plain flour. Allow to sit for about 1 hour while preparing the other ingredients.
Cut the cucumber lengthwise and use a spoon to remove the seeds. Then pat dry the cucumber and cut into 1 cm cubes.
In a bowl, add 2 1/2 TBsp of rice wine vinegar, 2 tsp of sugar and 1 tbsp of water. Mix well and add in the cucumber. Let it stand for 1 hr.
Cut the capsicum and tomatoes into 1 cm cubes.
Cut the chilli lengthwise to remove the seeds. Then cut it into strips.
In a bowl, add in the three remaining marinade ingredients (cornflour, rice flour and plain flour) and mix well. After the pork pieces have been marinated for 1 hr, add in the flour mixture and mix until well incorporated, and ready for deep-frying.
In a wok, add in the 250 ml of oil over high heat.
Once the oil is heated up, add in the pork pieces in small batches ensuring they are covered in oil and fry for about 3 mins until it turns golden brown. Transfer onto a plate lined with kitchen towel and let cool for about 10 mins. Turn off the heat.
Sieve out all the burnt bits from the oil. Then turn the heat to high and re-fry the pork pieces for a 2nd time in small batches for about 1 min.
Transfer pork pieces onto a plate lined with fresh kitchen towel and set aside.
In a clean pan, add in 1 Tbsp of oil. Once the oil is heated, add in the chopped garlic and fry till aromatic.
Add in the capsicum and fry for 2 mins. Then, add in the tomatoes, pineapple cubes and chilli, and stir fry for 1 min.
Next, add in the pickled cucumber together with vinegar, the 3 tbsp of tomato sauce, 1-2 tsp light soya sauce and 150 ml water. Continue to cook until the sauce starts to bubble.
Mix the 1 tbsp cornflour with 2 tbsp of water to get a smooth cornflour solution. Slowly add cornflour solution into the sauce, stirring it constantly until it thickens. Taste the sauce to see if more sugar or vinegar needs to be added, according to your preferred taste.
Transfer to a serving dish and serve hot with a bowl of steaming hot rice.
