Step 1

In a wok, medium pot, or saucepan, heat the oil over medium heat. Whisking constantly, make a roux by adding the flour, turmeric, and paprika. Continue whisking for 15-20 seconds, then add the garlic and shallot.

Step 2

Whisk for another 30 seconds. Next, whisk in 3 cups of the chicken stock. Bring the mixture to a simmer. Add the oyster sauce, light soy sauce, dark soy sauce, sesame oil, and white pepper to taste.

Step 3

Combine the cornstarch with the remaining ¼ cup of chicken stock (or use water) to make a slurry. Slowly stir in two-thirds of the mixture.

Step 4

Let the gravy cook and continue to thicken for 30 seconds. Add more of the cornstarch slurry if needed. The gravy should be thick enough to coat a spoon. Taste and adjust seasoning with additional salt or soy sauce according to your preferences. Serve!
