If using dried wood-ear mushrooms, soak in hot water to reconstitute them. After they have been rehydrated, chop off the stems, then finely mince. You will have about ⅓ - ½ cup of minced mushrooms.
Place ground pork, fish sauce, salt, pepper, shallots, garlic, and minced mushrooms and julienned betel leaves (if using) in a mixing bowl. Mix well to combine. You can cook a teaspoon of filling to taste and adjust seasonings to your liking.
Lay a large wild betel leaf glossy side down on a clean working surface. Place about a tablespoon of the meat filling on the leaf, form into a small log and then wrap with the leaf. Continue to wrap with the remaining filling and leaves.
Place a pan over medium heat. Once the pan is hot, add a generous amount of cooking oil. After the oil is heated, pan-fry the pork rolls in a single layer for 4-5 minutes or until fully cooked. Turn/rotate the rolls every 1-2 minutes.
Transfer to a wired rack or a plate lined with paper towel briefly to absorb excess oil. Serve hot. See Notes on ways to serve these rolls.
