作法
- 所有骨頭放入沸水中汆燙十分鐘。倒掉浮渣水，在水龍頭下把骨頭刷洗乾淨。這個步驟讓博多湯保持乾淨乳白色，而非混濁灰色。
- 把骨頭與豬背脂放回高湯鍋，加入蔥綠、大蒜、薑與5公升新鮮水。大火煮至劇烈翻滾——博多湯必須劇烈滾煮，不能慢燉，這樣膠原蛋白才會乳化。
- 至少滾煮8小時，最好12小時，視情況補熱水以維持水量。湯應從灰色轉為不透明的象牙白。每兩小時用厚湯匙敲碎骨頭，釋放更多骨髓。
- 湯熬煮的同時做叉燒：把捲起的五花肉放入醬油、味醂、清酒和500毫升水中燉煮兩小時至軟嫩。在湯汁中冷卻；這也是你的tare醬。
- 把湯以細濾網過濾，按壓固體濾出湯。每公升湯加入三大匙叉燒湯汁（tare）攪勻。試味——應有深沉的豬肉鮮味、鹹中帶甜。
- 麵條在無鹽水中按包裝指示煮熟——博多細麵通常90秒。瀝乾，用力甩乾。每碗倒入350毫升湯，放入麵條，加上叉燒片、半切味付玉子、青蔥、紅薑與芝麻。三分鐘內吃完——博多麵很快會軟。
Common questions
Can 豚骨拉麵 be made ahead?
豚骨拉麵 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 720 minutes.
Is 豚骨拉麵 spicy?
豚骨拉麵 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 豚骨拉麵 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 豚骨拉麵 to make at home?
豚骨拉麵 is more demanding — total time around 750 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 豚骨拉麵 be scaled up or down?
This recipe is written for 4 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
豚骨拉麵是九州對東京清湯醬油拉麵的回應——1940年代誕生於福岡，那珂川旁的屋台（街邊攤）。決定性的技術是持續劇烈滾煮：慢燉得到清湯；大滾才會讓油脂與膠原乳化成博多食客要求的乳白濁度。點「bari-kata」（極硬麵）並要求「kaedama」（吃到一半時加麵）是當地吃法。
