How to Make Onsen Tamago
Step 1: Prepare the Water Bath
Fill a medium-sized pot with water and heat it to about 70°C (158°F). This temperature is crucial for achieving the perfect texture.
Step 2: Add the Eggs
Once the water reaches the desired temperature, gently place the eggs in the pot. Make sure to lower them slowly to avoid cracking.
Step 3: Set a Timer
Cover the pot and set a timer for 15 minutes. This is the sweet spot for a creamy yolk and tender whites.
Step 4: Prepare an Ice Bath
While the eggs cook, prepare a bowl of ice water. This will stop the cooking process quickly once the eggs are done.
Step 5: Transfer the Eggs
After 15 minutes, use a slotted spoon to transfer the eggs to the ice bath. Let them cool for about 5 minutes.
Step 6: Crack and Serve
Gently crack the eggs into a small bowl. The whites should be set while the yolks remain beautifully runny.
Step 7: Season to Taste
Sprinkle a little salt over the eggs to enhance their flavor. You can also drizzle some soy sauce or dashi for added depth.
Step 8: Enjoy!
Serve your Onsen Tamago warm and enjoy it as a side dish, on rice, or in your favorite soup. It’s a warm hug in a bowl!
