Crafting Liu Ting Pig’s Trotter
The preparation of Liu Ting Pig’s Trotter involves meticulous attention to detail, encompassing the following six key steps:
- Ingredient Selection: Only high-quality pig trotters are chosen, which must be fresh, plump, white, and undamaged, with a balanced weight and intact tendons. Typically, trotters from ecologically raised pigs that are grain-fed for a year are used. Each trotter is carefully selected to ensure top-notch quality.
- Cleaning: The trotters undergo thorough cleaning in flowing water to remove surface impurities and are then soaked for an extended period to eliminate any residual blood, resulting in a tender and clean appearance.
- Marination: Natural spices are used in accordance with a standard recipe for marination, which usually takes 24 hours. This step is crucial for allowing the trotters to absorb rich flavors.
- Blanching: Multiple blanching treatments are performed to remove excess fat and odors from the trotters, making the skin more appealing and aromatic.
- Hair Removal and Cooling: Following traditional methods, the hair on the trotters is removed using a flaming technique, followed by washing with running water and rapid cooling to lock in moisture and nutrients.
- Sauce Preparation: Using high-quality Laoshan spring water from Qingdao, the trotters are simmered slowly with a secret broth for about 240 minutes. This long cooking process ensures that the trotters are fragrant yet not greasy, resulting in a glossy and translucent appearance.
Flavor and Characteristics
Liu Ting Pig’s Trotter is renowned for its vibrant color, delightful flavor, and refreshing taste, striking a perfect balance between saltiness and sweetness. The meat is tender yet firm, boasting a chewy and gelatinous texture. The transparent gelatine formed during the cooking process adds a unique crunch that leaves a lasting impression on diners. Additionally, Liu Ting Pig’s Trotter is rich in collagen, minerals, and vitamins, offering numerous health benefits.
Dietary Considerations
Despite its delicious taste and rich nutritional profile, Liu Ting Pig’s Trotter may not be suitable for everyone. Due to its high cholesterol content, individuals with weak digestive systems, such as the elderly and children, should consume it in moderation. It is also advisable to avoid eating pig trotters before bedtime, as this could increase blood viscosity. Furthermore, older adults suffering from chronic hepatitis, cholecystitis, or gallstones are advised to refrain from consuming trotters, as it could exacerbate their conditions or trigger old ailments.
