Reducing Gamey Smells in Broth | Generated by AI
That smell you’re describing—often called “sāo wèi / 臊味”—is actually very common with beef bones (牛椎骨) and certain wild or game-type meats like rabbit, but much less common with pork bones. Here’s why it happens and what to do about it.
Why beef bones have that smell
Beef bones tend to carry a stronger scent because:
1. Higher myoglobin content
Cattle muscles and the tissues around the spine (椎骨) contain more myoglobin than pork. Myoglobin breaks down during cooking and gives off a distinct “raw animal / iron-like / slightly gamey” smell.
Pork has much less myoglobin → milder aroma.
2. More marrow and trapped blood in 牛椎骨
Spinal bones have:
- Deep marrow channels
- More residual blood
- More connective tissue
These release compounds like amines and fatty acids that produce a stronger 臊味.
Pork bones usually have less trapped blood and cleaner fat.
3. Rabbit meat contributes its own wild/game smell
Rabbit (especially farmed rabbit) still carries:
- faint wild/gamey scent
- unsaturated fats that oxidize easily
- sometimes a slight “metallic” smell
When you cook rabbit + beef spine bones together, the smell increases instead of balancing out.
4. Shangyao (山药) doesn’t cover the smell
Mountain yam is neutral and slightly sweet— it does not absorb or neutralize 臊味. So the smell stays in the broth.
How to remove or reduce the smell next time
Here are reliable methods used in Chinese kitchens:
1. Blanch (焯水) properly
This is the most important step.
- Cold water start
- Add bones
- Bring to a full boil
- Remove all foam
- Rinse bones with hot water
If the water smells strong → that’s the 臊味 being removed.
2. Fry the bones briefly before boiling (小煸一下)
A light pan-fry until the bone surfaces turn slightly golden helps remove raw animal smell.
3. Add spices that specifically target 臊味
These are effective:
- 姜 (lots of it)
- 花椒
- 料酒
- 大葱段
- 白胡椒
- 丁香 (very tiny amount!)
Avoid too many herbs (中药材) because they don’t remove 臊味; they just add more aroma layers.
4. Avoid mixing rabbit + beef bones
If you want a very clean taste:
- Rabbit works better with pork bone or chicken bone
- Beef bone works better with radish, carrot, or corn, but not with rabbit
Mixing the two tends to amplify each other’s gamey notes.
5. Remove fat
Beef bone fat can be strong. If you chill the soup later, remove the top fat layer—it reduces the odor a lot.
Summary
Your soup has 臊味 because:
- Beef spinal bones naturally have a stronger, blood-heavy smell
- Rabbit also has a slight game scent
- Combining the two intensifies it
- Shangyao doesn’t neutralize that smell
With proper blanching, spices, and not mixing rabbit with beef bones, the result will be much cleaner.
