Cover the raw peanuts in water and soak for about 15 minutes. Then drain well.
Cut the kaffir lime leaves into thin strips or small pieces.
Heat the oil in a fry pan or wok over medium heat until it reaches 260°F (125°C). We need enough oil to cover the peanuts so the exact amount of oil will depend on the shape and size of your pan.
Add the peanuts to the pan and fry over medium heat. Adjust the heat as needed to avoid overheating and burning the peanuts. Give them a stir every now and then.
Fry for about 20 minutes or until you smell a toasty flavor. Check the doneness to see if the nuts are crisp and golden.
Add the kaffir lime leaves and fry for about 1½ - 2 more minutes. Remove the nuts and leaves from the oil with a slotted spoon. Toss well with salt.
Once the peanuts have cooled, you can store them in an airtight container in the fridge. They will stay crunchy even after a week.
