1. Add 3 cups neutral oil to the pot and bring it to 340ºF (170ºC) over medium heat. Make sure your oil is 1¾–2 inches (5 cm) deep in the pot. Tip: If you don’t have a thermometer, stick a chopstick in the oil; you‘ll know the oil is hot enough when you see tiny bubbles start to appear around the tip. Alternatively, you can drop one piece of panko into the oil; if it sinks down to the middle of the oil and immediately pops back up to the surface, then the oil is ready.
2. Gently put one piece of pork into the oil and cook for 1 minute (without flipping). Don‘t touch the pork for 30 seconds. Tip: Why one piece at a time? You don‘t want to reduce the oil temperature drastically. The size of the bubbles should be big when you add the pork. Keep watching the oil temperature and make sure it doesn’t go over 340ºF (170ºC) or else the breading will get dark too quickly before the pork is done cooking, resulting in undercooked meat.
3. After a minute, flip the pork and cook the other side for 1 minute.
4. Take out the pork and remove excess oil by holding it vertically over the pot for a few seconds while the oil drips off. Place it on a wire rack or paper towel and let it sit for 4 minutes. The hot oil on the exterior will slowly continue to cook the meat as it sits.
5. Turn off the heat temporarily and scoop up and discard any fried crumbs in the oil with a fine-mesh strainer. It’s very important to keep the oil clean and crumb free so the oil does not get darker and dirtier with burnt crumbs. Turn on the heat and bring the oil back to 340ºF (170ºC).
6. While the first cutlet is resting on the wire rack, deep-fry the second piece of pork for 1 minute without flipping. Remember not to touch it for 30 seconds.
7. Flip and cook the other side for 1 minute.
8. Take out the pork and remove the excess oil as before. Place it on the wire rack and let the residual heat cook the pork for 4 minutes. Scoop up and discard the fried crumbs in the oil with a fine-mesh strainer.
