Make sure your container is clean and free of oil. Drain with kitchen paper if there is water inside.
Place the cleaned bok choy in, add garlic cloves, fresh Thai peppers, salt, and rice vinegar. Then pour in hot boiling water.
Place the plate as a weight so that all parts of the Bok Choy are submerged in the brine.
Cover the lid, wait overnight, and you will get beautifully pickled Bok Choy.
Fry it up
Frying can remove the extra water of pickled bok choy and enhance the flavor. The easiest way is to stir fry the bok choy with around 3 tablespoons of oil, should be a little bit more, then add a very small pinch of salt and light soy sauce. You can keep the pickled peppers if you prefer a hot version.
Another way is to fry with pork belly: cut the pork belly into small pieces. Heat the oil and sear the pork belly. Add garlic, ginger, scallion, and chili pepper. Fry until aromatic—season with salt and soy sauce.
