Clean & Soak: Wash the tripe thoroughly, soak it in the vinegar for about 20 minutes, then wash and dry it completely.
Boil: Boil the tripe with the sea salt, kaffir lime leaves, and lemongrass until it is fork-tender (checking every 10 minutes).
Season: Cut into large pieces and toss with the oyster sauce, sugar, chicken bouillon, MSG, black pepper, garlic powder, and crushed lemongrass. Tip: Taste-test the seasoning blend before letting it sit so you can adjust the saltiness or sweetness to your liking.
Grill: Grill on high heat for 5–10 minutes per side over hot coals for that smoky BBQ flavor, watching closely to prevent burning.
