Method
- 1 Peel the onions and cut them into 2 cm thick wedges; cutting them thinner will cause them to become mushy after two days.
- 2 Arrange the onions in a glass container that has been rinsed with boiling water and allowed to dry completely.
- 3 Simmer soy sauce with vinegar, sugar, dried chili peppers, cinnamon, star anise, and 120 ml of water for 6 minutes.
- 4 Pour the hot soaking water over the onions and cover immediately; pouring the hot water cooks the onions until tender but still keeps them crisp.
- 5 Let it cool, then refrigerate for 3 days; after that, strain the liquid, boil it again, and pour it back in for a second time to preserve it for longer.
