Onsen Egg Recipe at Room Temperature
Onsen eggs, also known as Japanese hot spring eggs, are a type of soft-boiled egg cooked in hot water at a precise temperature. Unlike traditional hard-boiled or soft-boiled eggs, onsen eggs have a unique texture that is both tender and creamy, with a slightly runny yolk.Cooking
eggs at room temperature allows for more precise control over the cooking process, resulting in a consistent and desirable texture. This method is particularly beneficial for those who prefer their eggs with a slightly runny yolk.
Step-by-Step Instructions for Preparing Onsen Eggs at Room Temperature:
1. Gather your ingredients
fresh eggs, a large pot, a thermometer, and a slotted spoon.
- Bring a large pot of water to a boil.
- Remove the pot from the heat and let it cool for 5 minutes.
- Add the eggs to the hot water and use a thermometer to monitor the temperature.
- Maintain the water temperature between 62-65°C (144-149°F) for 1 hour and 15 minutes.
- Remove the eggs from the water and immediately transfer them to an ice bath to stop the cooking process.
- Peel the eggs and enjoy them immediately or store them in the refrigerator for up to 3 days.
Science Behind Onsen Eggs
Onsen eggs, also known as hot spring eggs, are cooked in water baths at temperatures ranging from 60 to 70°C (140 to 158°F) for an extended period. This low-temperature cooking method yields eggs with a tender, creamy yolk and a firm, custardy white.
Preservation of Texture and Flavor
The low-temperature cooking process coagulates the egg white proteins gradually, preventing the formation of tough, rubbery textures. The yolk remains runny due to the lower temperature, preserving its rich flavor and creamy consistency.
Nutritional Value
Onsen eggs retain a similar nutritional profile to other cooking methods. However, the low-temperature cooking process may preserve certain heat-sensitive nutrients, such as vitamin B12 and riboflavin.
| Cooking Method | Calories | Protein (g) | Fat (g) | Carbohydrates (g) |
|---|---|---|---|---|
| Onsen | 70 | 6 | 5 | 1 |
| Boiled | 71 | 6 | 5 | 1 |
| Fried | 90 | 6 | 7 | 1 |
Variations and Accompaniments
Onsen eggs offer a versatile canvas for culinary creativity. Experiment with various seasonings and sauces to enhance their flavor.
One popular variation is the shoyu onsen egg, where the egg is marinated in soy sauce. Other options include adding mirin, sake, or dashi to the marinade for a richer flavor.
