Bring a pot of water to boil, carefully lower eggs into pot. Lower heat and simmer for 7 minutes. Lift eggs out of hot water and place in an ice-water bath.
When cool enough to handle, peel shells and place eggs into a sealable bag.
Combine all marinating sauce ingredients, stirring to dissolve sugar. Pour sauce into bag with eggs. Squeeze out all the air and seal bag.
Let eggs marinate for 1 – 2 hours. Remove and slice in half to serve. Garnish with pepper chili salt.
