To make the pork belly: In a small bowl, whisk together fish sauce, sugar, water, garlic and black
pepper. Place pork belly in a large Ziploc bag, pour in marinade, seal bag, and toss to evenly coat
pork. Place in refrigerator and marinate for 4 hours up to 24.
Fire up smoker or grill to 225°F, adding chunks of smoking wood chunks when at temperature. When
the wood is ignited and producing smoke, place pork belly pieces in the smoker or grill, cover, and
smoke for 3 hours.
To make the glaze: While the pork is smoking, in a small saucepan set over medium heat, whisk
together sugar, honey, fish sauce, and water. Bring to a boil, reduce heat to low, and let simmer until
slightly thickened, about 5 minutes. Remove from heat.
Transfer pork belly pieces to an medium square pan or foil tray, pour in glaze, and toss to coat. Cover
pan with foil and place in smoker for 45 minutes. Remove foil cover from pan and continue to smoke
for 15 minutes more. Remove pork from smoker.
