Then turn it right side out and squeeze out the excess water. Combine softened dried chilies, 1/2 tsp salt, lemon grass, cilantro roots, Kaffir lime zest, galanga, garlic and onions in a blender and grind to a paste. Mix the chili paste, pork, Kaffir lime leaves, cilantro leaves and fish sauce well. Tie a knot a one end of the casing and stuff with the pork mixture. Tie another knot to close. Poke a few holes with a clean needles where the bubbles are present inside. Charbroil or fry over medium-low heat until golden brown and fully cooked. Poke a few holes while cooking to prevent rupturing. Slice into 1/2" thick pieces. Serve with cooked sticky rice and raw vegetables. Makes about 5 servings. From Gail Shimizu.
