You can make soft or hard boiled eggs the day before and let them sit in a marinade. They soak up flavor like little sponges.
Simple marinade: ¼ cup soy sauce, ¼ cup mirin or water, 1 teaspoon sugar, a crushed garlic clove. Submerge peeled eggs in this for 4–24 hours.
Eat them cold or warm. They’re incredible on rice, noodles, or just alone as a snack that makes you feel like a culinary genius.
