### **Step 1: Cleaning and Prepping**
Rinse beef tendon thoroughly under cold running water.
Trim any excess fat or tough bits using a sharp knife.
Soak in cold water for 2-3 hours or overnight to remove impurities. Adding vinegar or lemon juice can help tenderize.
### **Step 2: Cooking Methods**
**Option 1: Slow Braising (4-6 hours)**
Place the tendon in a pot with water and bring to a boil. Skim off impurities.
Drain and rinse, then add fresh broth, soy sauce, ginger, garlic, and salt.
Simmer on low heat for 4-6 hours until gelatinous and tender.
**Option 2: Pressure Cooking (45-60 minutes)**
Place tendon in a pressure cooker with broth, soy sauce, ginger, and garlic.
Cook on high pressure for 45-60 minutes, then release pressure naturally.
### **Step 3: Serving Suggestions**
- Slice thinly and serve in Vietnamese pho.
- Add to Chinese beef noodle soup.
- Use as a topping for rice or porridge.
- Enjoy as a crispy snack by frying after braising.
