You will need
1/2 dozen eggs, hard boiled
2-3 Tbsp dark soy sauce
1/2-1 anise star
2 tea bags (black or green tea)
Crack hard boiled eggs lightly against a firm surface to create an even crackling throughout the whole egg surface. Do not peel off the egg shell. Place eggs in a small pot, cover with enough boiling water to submerge the eggs. Add the remaining ingredients. Simmer for 1-2 hours and let eggs cool in liquid over night. The longer you keep the eggs in solution, the more noticeable the marble pattern.
