Prep:
- Marinate the pork: Clean and pat-dry the pork collar meat. Thinly slice against the grain into bite-sized pieces. Add to a medium bowl, followed by the light soy sauce, fish sauce, ground white pepper, and corn starch. Mix well with a spoon to combine, then set aside.
- Make the sauce: Whisk together the oyster sauce, light soy sauce, sweet dark soy sauce, fish sauce, and white sugar in a small measuring cup (for easier pouring) or bowl until evenly combined.
- Prepare the fresh ingredients: Roughly chop the garlic, red and green Bird’s eye chilies, and Prik Kee Nu green chilies, and large red chili. Using a mortar and pestle, pound the garlic until bruised (leave some chunky pieces), then transfer to a small bowl. Add all the chilies to the mortar and a pinch of fine sea salt (to help break down the fibers) and pound into a coarse paste. Transfer to another small bowl and set aside. (Note: You can pound the garlic and chilies together into a paste, but I prefer to pound them separate so that are some big garlicky pieces in the final stir-fry dish. If you don’t own a mortar and pestle, crush the garlic with the flat side of your knife and then roughly chop. Finely chop the chilies.) Prepare the yellow onion, baby corn, and Thai holy basil leaves as indicated in the ‘ingredients’ section.
For the Thai Basil Pork Stir-fry:
- Sauté the pork: Heat the canola and chili oil (if using) in a large wok over high heat. Once hot, add the marinated pork and immediately spread out the pieces in the wok. Allow to cook for 40 seconds, then stir-fry for 30 seconds until lightly browned but still pink in some parts.
- Stir-fry the onion and aromatics: Add the onion and stir-fry for 40 seconds to combine with the pork, then turn the heat down to medium-high and add the smashed garlic and chilies. Stir-fry for 40 seconds until fragrant.
- Add the baby corn and sauce: Add the baby corn and stir-fry for 20 seconds to combine. Then pour in the sauce and toss briefly until everything is evenly coated in it.
- Simmer: Pour in the chicken broth and stir to combine. Simmer at medium-high heat for a minute.
- Add the basil leaves: Stir in the Thai holy basil leaves and simmer for 30 seconds until wilted. Switch off the heat.
- To Serve: Transfer to a serving bowl/dish and serve immediately with warm steamed rice.
