🐷 Why is roast pork skin so crispy? Uncover the secrets of Hong Kong-style crispy roast pork

I'm a self-proclaimed "siu mei fanatic." Every time I go to a siu mei shop, the thing I look forward to most is the siu rou ! The skin is so crispy it makes a crackling sound, and the gravy is so juicy it's truly addictive! 😍 But here's the question: How does siu rou get so crispy? There's actually a lot of ingredient preparation and cooking techniques behind it. Let's delve deeper!

📜 A short history of barbecue

1. Representative of Guangdong barbecue culture

Roast pork, also known as "crispy roast pork" or "roasted pork belly" in Cantonese, is the heart and soul of Cantonese barbecue. Originally prepared by rural chefs for festivals and banquets, it later became the hallmark of street barbecue shops.

2. Hong Kong style evolution

Hong Kong roast pork places particular emphasis on crispy skin and tender meat. The chef will use traditional hanging oven roasting methods or modern high-temperature ovens, repeatedly adjusting the heat to achieve the effect of crispy outside and fragrant inside.

🧪 Why is the roast pork skin so crispy?

1. Characteristics of cortical structure

• Pig skin itself is rich in collagen and fat.
• When baked at high temperature, the collagen dehydrates and shrinks, the fat is forced out, and a layer of "brittle grid" is formed in the skin.
• This process is the key to making the roasted pork skin "crunchy".

2. Curing and air-drying process

• The traditional method is to marinate the pork belly first, then pierce the skin densely with a needle🪡.
• Then apply vinegar or lemon juice to tighten the skin and prevent bubbles.
• The most important thing is to air-dry the dough. Some chefs even air-dry it overnight to completely remove moisture from the surface. A dry, crispy skin is easier to bake.

3. High temperature peeling technology

• Roasting meat usually takes place in two stages:
  1. First, roast slowly over medium heat until the meat is cooked through and the fat is released.
  2. Then, high temperature is used to "pop the skin"🔥, causing the skin to expand and crack instantly, creating a crispy effect.
• This technique requires precise control of the heat, otherwise it will burn or be too hard.

4. The role of oil

• The pork belly has thick fat under the skin, and when it is grilled, the fat slowly seeps out and penetrates into the surface of the skin.
• Under high temperature, the oil helps to fry the crispy layer, making the taste naturally more crispy.

5. Post-processing

• Some chefs will also use salt to press the skin, or use a torch to burn it after roasting to further make the skin crispy and distinct.
• When cutting the roast pork, be sure to use a sharp knife to avoid crushing the crispy skin and maintain the intact taste.

1. Taste comparison

• Crispy : The skin is crispy and fragrant.
• Tender : The meat remains juicy and not dry.
• Aroma : The fat penetrates and brings out the rich aroma of pork.

2. Visual Effects

The golden roasted pork skin with cracks is enough to make you drool just by looking at it🤤.

3. Symbol of food culture

Crispy roast pork has become one of Hong Kong's "Three Treasures of BBQ" (barbecued pork, roast duck, and roast pork), and it has a place at every family dinner table, wedding banquet, or neighborhood fast food.

🍖 Modern Variations and Innovations

1. Homemade Crispy Roast Pork

Many families use air fryers or ovens to make their own. Although the firepower is not as strong as that of a professional hanging oven, it can still achieve a crispy effect.

2. Fusion of Chinese and Western cultures

Some restaurants pair crispy roast pork with red wine, mustard sauce, or even combine it into a Western-style platter to enhance its international appeal🍷.

3. Molecular gastronomy version

Some high-end restaurants use molecular cooking technology to precisely control temperature and humidity to make the crispy skin more uniform.

💡 Editor's Summary
