rare + noun (steak, meat, lamb, beef)

用法筆記

This sense applies only to red meat (beef, lamb, venison) and tuna. It is never used for chicken, pork, or fish other than tuna. The doneness scale for steak is: blue → rare → medium-rare → medium → medium-well → well-done.

常見錯誤

I ordered my chicken rare.
I ordered my steak rare.
💡never use 'rare' for chicken or pork; they must be cooked through for safety.

❌ 'The steak was very rare.' (acceptable for intensity) — more naturally: 'The steak was cooked rare.' or 'The steak was quite rare.' — 'cooked rare' is the most common pattern.

    technical term used in physiology and mountaineering

反義詞
  • dense

    air containing more oxygen; found at or near sea level

  • heavy
