作法
- 牛肉以紹興酒、生抽、太白粉、小蘇打與1大匙油醃20分鐘。小蘇打是粵式嫩肉劑——改變蛋白結構讓牛肉在大火下保持絲滑。
- 炒鍋以最大火加熱至冒煙閃光。加1.5大匙油晃勻。牛肉鋪一層煎30秒；翻面再煎20秒。在完全熟前撈出。
- 下剩餘油。爆香洋蔥與青蔥20秒。加入河粉，用筷子（不是鏟子）翻拌——筷子撥起，鏟子壓碎。
- 從鍋邊淋入老抽與生抽，讓它們先碰熱鍋。用力翻炒60秒；每根河粉應均勻染上琥珀色。
- 牛肉回鍋並加豆芽。翻拌30秒——豆芽應仍脆，牛肉剛剛熟透。
- 盛盤。應呈光亮，河粉深琥珀色帶焦邊，牛肉絲滑，豆芽淡綠脆口。底部不應積醬汁——鍋氣意指乾、煙、焦。
Common questions
Can 乾炒牛河 be made ahead?
乾炒牛河 is best made and eaten the same day, but the components can be prepped earlier — chop and measure the ingredients up to a day ahead, refrigerated separately. Final cooking takes about 5 minutes.
Is 乾炒牛河 spicy?
乾炒牛河 as written is mild to mildly warming — the heat comes from aromatics rather than chili. Add fresh sliced chili or chili oil at the end if you'd like to push it spicier.
Is 乾炒牛河 vegetarian or gluten-free?
This recipe is suitable for most diets. If you have specific restrictions, the substitutions section in each ingredient note covers the most common swaps.
How hard is 乾炒牛河 to make at home?
乾炒牛河 is more demanding — total time around 20 minutes plus marinating/resting where noted. Specific technique (knife work, wok hei, fermentation) makes the difference between a passable result and the real thing.
Can 乾炒牛河 be scaled up or down?
This recipe is written for 2 servings. To scale, multiply each ingredient proportionally; the cooking times stay the same up to about double the volume. Beyond that, expect to cook in batches because of pan size and heat distribution.
文化背景
乾炒牛河是區別粵廚與業餘者的料理。鍋火必須夠強——香港餐廳爐火達20萬BTU，是家用爐的十倍。家庭廚師折衷做法是分小批炒，並讓鍋在每批間恢復溫度。招牌在於河粉的氣味：焦化的醬油、火氣、難捉摸的鍋氣，無其他技法能複製。家中常見錯誤是醬油下太多；老抽用於上色，生抽用於調味。
