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。

- 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

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

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

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

- 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

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

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
