How to Make It
In a blender, combine the ginger, soy sauce, sesame oil, peanut butter, sugar, vinegar, rice wine, garlic, sesame paste, shallot and 3 tablespoons of the peanut oil and puree until smooth. Transfer the sauce to a bowl and refrigerate for 45 minutes.
In a large pot of boiling water, cook the noodles until al dente. Drain and rinse under cold running water until chilled. Shake out the excess water and blot dry; transfer the noodles to a bowl and toss with the remaining 2 tablespoons of peanut oil. Add the peanut-sesame sauce and toss well to coat. Garnish with the cucumber and scallions and drizzle with Ma La Oil, leaving the solid spices behind.
The peanut-sesame sauce can be refrigerated for up to 3 days.
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.
