Onsen eggs originate from Japan. The whites are a semi-liquid curd, while the yolks are gently set, giving a silky, smooth texture — the opposite of a soft-boiled egg. Eggs are rich in high-quality protein, lecithin, and various vitamins, making them very nutritious.温泉蛋源自日本,蛋白呈半流动凝乳状,蛋黄却温润凝固,口感滑嫩细腻,与溏心蛋恰好相反。鸡蛋富含优质蛋白、卵磷脂和多种维生素,营养十分全面。

Onsen Egg — ingredients and steps overview

Method6 steps

  1. 1

    Preparation and Temperature Control

    准备与控温

    Fill the pot with a certain amount of tap water, ensuring the water level covers the eggs by about 3cm. Insert a thermometer into the water. Turn on the heat and gradually adjust the power to keep the water temperature at 70°C.

    在锅中盛装一定量自来水,确保水面没过约鸡蛋 3cm,水中插入温度计。开火逐渐调整功率,使水温保持在 70 摄氏度。

    5 min

    • If using a mechanical thermometer, the probe must be submerged in the water by at least 6cm.若使用机械式温度计探头需没入水中至少 6cm
    • Use a slightly thicker pot to make temperature control easier.锅可以采用稍厚的锅,方便控制温度
    Step 1: Preparation and Temperature Control
  2. 2

    Add the Eggs

    放入鸡蛋

    Place the eggs into the pot. The eggs must not be stacked on top of each other; they should all rest at the bottom with enough space to move slightly.

    将鸡蛋放入锅中。鸡蛋不可互相堆叠,应皆在底部,并留有空间可以晃动。

    30 sec

    • Handle gently to prevent the shells from cracking.动作要轻,防止蛋壳破裂
    Step 2: Add the Eggs
  3. 3

    Cook at Constant Temperature

    恒温烹煮

    Keep the water at 70°C and continue heating for 25 minutes.

    保持当前 70 摄氏度水温持续加热 25 分钟。

    25 min

    • Watch the thermometer patiently and adjust the heat as needed.需要耐心观察温度计,随时微调火力
    Step 3: Cook at Constant Temperature
  4. 4

    Prepare Ice Water

    准备冰水

    While the eggs are cooking, prepare a cup of ice water.

    在烹煮过程中,准备一杯冰水备用。

    1 min

    • Ice water cools the eggs quickly, preventing residual heat from overcooking the yolks.冰水能让鸡蛋迅速降温,防止余温过度加热蛋黄
    Step 4: Prepare Ice Water
  5. 5

    Chill in Ice Water

    冰镇降温

    Remove the eggs and immediately place them in the ice water. Wait for 3 minutes.

    捞出鸡蛋,并立刻放入冰水中,等待 3 分钟。

    3 min

    • Place them in the ice water immediately.必须立刻放入冰水
    Step 5: Chill in Ice Water

    Serve in a Bowl

    装碗完成

    Crack the eggs into a small bowl, add kombu soy sauce, and garnish with scallions.

    将鸡蛋打入小碗,加入昆布酱油和葱花点缀。

    1 min

    • Onsen egg whites are tender, so crack the eggs carefully.温泉蛋蛋白较嫩,打蛋时需小心
    Step 6: Serve in a Bowl

Extra tips

  • If using a mechanical thermometer, the probe must be submerged in the water by at least 6cm. If using an electronic thermometer, there are no special requirements.若使用机械式温度计则探头需没入水中至少 6cm,若使用电子温度计则无特殊要求
  • Use a slightly thicker pot to make temperature control easier.锅可以采用稍厚的锅,方便控制温度
  • Although 70°C for 25 minutes is sufficient to kill Salmonella, it is still best to eat them in moderation or use certified raw-edible eggs.虽然 70 摄氏度 25 分钟已经完全可以杀死沙门氏菌,但还是要尽量少吃,或购买正规可生食鸡蛋制作
