作法
- 昆布在1公升冷水中浸泡30分鐘（更久更好——冰箱過夜最佳）。慢慢加熱至剛沸前，邊緣冒出小泡時撈出昆布。
- 把柴魚片加入昆布水。立即關火——餘溫足夠。靜置兩分鐘；柴魚片會在釋放風味時下沉。
- 用鋪了廚房紙的細濾網過濾。不要按壓柴魚片；按壓會出苦味。這就是一番出汁，用於清湯的首取高湯。
- 把高湯倒回鍋中。加熱至剛將沸騰——加入味噌後絕不可煮沸。加入豆腐丁與泡好的海帶芽。
- 把味噌放入小湯勺中浸入湯裡，用筷子攪拌至味噌均勻散入高湯不結塊。離火攪散保留活菌與香氣。
- 試味——湯應鹹香，後段有高湯的清楚低音，味噌在上方一層。倒入小漆碗或瓷碗。撒青蔥。直接從碗喝湯，用筷子夾豆腐。
Common questions
Can 味噌湯 be made ahead?
味噌湯 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 8 minutes.
Is 味噌湯 spicy?
味噌湯 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 味噌湯 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 味噌湯 to make at home?
味噌湯 is approachable for a home cook with basic stove skills — total time about 13 minutes, no special technique required.
Can 味噌湯 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
味噌湯是傳統日本早餐三大支柱之一（飯、味噌湯、漬物），也是幾乎所有餐廳定食的收尾菜。高湯品質就是整道菜；即溶高湯粉與味噌醬可做出尚可的一碗，但仔細的昆布柴魚高湯會徹底改變這道湯。味噌有許多地方類型——京都的白味噌甜而快速發酵；名古屋的紅味噌深而幾乎不甜。許多家庭混用。
