The marinated is flavored with sesame oil and salt. The eggs look plain and white, but are amazingly good! Try them with rice, or as a great drinking appetizer too!
I thought up a variation on the usual soy sauce marinated eggs you get at ramen restaurants.
I recommend marinating soft-boiled eggs. Add some garlic or ra-yu sesame chili oil to taste. I use coarse salt in the marinade. Regular table salt is very salty so 1 teaspoon should be enough.
