large ox intestine marinated with a sweet teriyaki sauce
Thoroughly clean the large ox intestine by rinsing under cold water. Remove any excess fat and membranes, then soak in a mixture of vinegar and water for about 30 minutes.
In a bowl, combine soy sauce, brown sugar, mirin, minced garlic, grated ginger, and sesame oil. Stir until the sugar is dissolved.
Place the cleaned ox intestine in a large resealable bag or container and pour the marinade over it. Seal and refrigerate for at least 2 hours, preferably overnight.
Preheat the grill to medium-high heat. Remove the intestine from the marinade, reserving the marinade for basting. Grill the intestine for about 15-20 minutes, turning occasionally and basting with the reserved marinade, until nicely charred and cooked through.
Once cooked, remove the intestine from the grill, let it rest for a few minutes, then slice into bite-sized pieces. Garnish with chopped green onions and toasted sesame seeds before serving.
