How to Make It
In a small saucepan, heat the oil over low heat to 175°. Add the ginger, star anise, cinnamon, shallot, garlic, Sichuan peppercorns and chiles and cook over moderately low heat until the oil reaches 225°. Simmer at 225° for 5 minutes, then transfer to a heatproof jar and let cool. Stir in the sesame oil.
The Ma La Oil can be kept in a sealed jar at room temperature for up to 1 week.
Roasted peanut oil, as opposed to neutral peanut oil, smells richly nutty. Boyajin’s Fragrant Peanut Oil is available at specialty markets and from mingspantry.com.
