Common Questions
What cut of pork is best for char siu?
Pork shoulder is the most forgiving and flavorful. Pork butt, shoulder steaks, or country-style ribs work great. Pork tenderloin is leaner and can dry out faster, but it still works if you keep an eye on temperature and do not overcook.
Do I need maltose?
No. Maltose gives the classic glossy, slightly chewy finish, but honey is the easiest substitute. Brown sugar also works. If using maltose, warm the jar in hot water so it loosens, then measure.
How do I get the red color without food dye?
You have options: red yeast rice powder (traditional), beet powder (milder and more natural), or just skip coloring entirely. The flavor is still very much char siu.
Is red yeast rice powder the same as red yeast rice supplements?
Not exactly. For cooking, look for red yeast rice powder or angkak sold as a food ingredient. Supplements vary in strength and additives, and some may contain statin-like compounds (monacolin K). Quality can vary a lot, so buy from reputable food sources and skip the capsules for this recipe.
Can I make char siu in an air fryer?
Yes. Air fryers are basically edge-making machines. You can cook it fully in the air fryer in batches, or do the main roast in the oven and use the air fryer for a quick, sticky finish.
Air fryer method (fully cooked): Preheat to 380°F. Arrange pork in a single layer. Air fry 10 to 14 minutes total, flipping and basting halfway through, until the thickest part hits 145°F (tenderloin) or 150 to 155°F (shoulder for a juicier slice). Then bump to 400°F for 2 to 4 minutes to caramelize, watching closely.
What internal temperature should I cook it to?
For whole cuts of pork, 145°F with a rest is the food-safe minimum. For shoulder, I like pulling it around 150 to 155°F for texture and juiciness, but that is a preference, not a safety requirement. Tenderloin: pull at 145°F. With sugary glaze, it is easy to chase color and accidentally overcook, so trust the thermometer and let the broiler do the browning.
