Step 1

Cut the onions and peppers in 1-inch chunks and set aside

Step 2

If you are using fresh pineapple, core and peel it and then cut them into 1-inch chunks and set aside. If you are using canned pineapple, drain it and cut them into 1-inch chunks if you are using pineapple rings. Put them in a bowl and set aside.

Step 3

Cut the pork into 1-inch chunks and place it in a bowl.

Step 4

Grate the ginger, garlic, and onion and place it in the bowl with the meat.

Step 5

Add soy sauce to the bowl and mix everything very well.

Step 6

Let it marinate for 1 hour.

Step 7

Once the meat has finished marinating, in the bowl or plate - separate the meat slightly so they are not clumped together.

Step 8

Add half the potato starch over the meat and gently toss it in the potato starch until each piece has been coated with potato starch. Let it rest for 5 minutes until the potato starch has absorbed the marinade and moisture, and the batter looks gummy and moist.

Step 9

Add the rest of the potato starch on a large plate and dip each piece of pork into the potato starch one by one until each piece is well coated.

Step 10

If you are using a deep fryer, set the temperature to 350F (180C) and wait for the oil to get to temp. If you are using a frying pan, set the heat to medium heat and make sure there is at least 1 inch of oil in the pan.

Step 11

Add the meat in when the oil is hot, careful not to overcrowd the pan. (Depending on how big your pan is, you may need to do it in 2 batches). Cook the meat for approximately 5 minutes until it is crispy and browned.

Step 12

Remove the crispy pork and let it drain on a rack or a plate with something absorbent like newspaper or paper bag and set aside.

Step 13

In a clean frying pan, add in 2-3 tablespoons of oil, and set the stove to medium heat.

Step 14

Add in the tomato paste when the oil is hot and toast the tomato paste for 1-2 minutes until the oil has turned orange

Step 15

Add in the white vinegar, water, sugar and soy sauce and mix well and let it cook for 5 minutes.

Step 16

In a small bowl, dissolve the potato starch in cold water. Slowly pour it into the sauce but make sure you are constantly stirring it so it doesn't clump.

Step 17

Once the sauce has thickened, add in the peppers, pineapples, and onions and cook it for 1-2 minutes. Use your spatula to separate the onion chunks into smaller pieces.

Step 18

Add in the crispy pork and coat each piece with the sweet and sour sauce once the meat has all been coated, turn off the heat. Try not to cook the crispy pork in the sauce for too long, this will make the batter soggy. You just want to quickly coat the crispy pork with the hot sweet and sour sauce for a 1 minute and then plate it.

Step 19

Plate it and serve with rice! Enjoy! :)
