No hoisin, no nam yue — still sticky, still caramelized, still the dark-edged char siu you want over a bowl of rice. Pantry staples and an air fryer do the work; extra garlic carries the savory backbone where ketchup used to sit.
This is the simplified version — no hoisin, no nam yue. Six cloves of garlic carry the savory backbone where ketchup used to sit; dark soy carries the color on its own. If you don't have dark soy, use 4 tbsp regular soy total and add an extra half tablespoon of brown sugar to compensate.
Pork shoulder or collar (梅頭) gives you the marbling that turns char siu sticky instead of dry. A lean cut like loin will work but the texture suffers — if that's what you have, knock the second-side cooking time down to 7–8 minutes.
The dark, lacquered edges come from the final 200°C / 400°F glaze pass, not from the long cook. Resist the urge to skip it. Watch the meat during those last few minutes — every air fryer runs a little different.
