Step 1

Bring shallots, garlic, oil, cinnamon, and star anise to a simmer in a medium saucepan over medium heat. Cook, reducing heat as needed to maintain a gentle simmer and swirling pot occasionally, until garlic and shallots are browned and crisp, 20–25 minutes. (Take your time—you want to drive all the moisture out before they brown.)

Step 2

Mix ginger, red pepper, soy sauce, and sugar in a medium bowl. Strain shallot mixture through a fine-mesh sieve set over ginger mixture. Let garlic and shallot cool in sieve (this will allow them to crisp further) before stirring back into chile oil.

Step 3

Do Ahead: Crisp can be made 1 month ahead. Cover and chill.
