Chicken with Black Pepper and Garlic
Using either a mortar and pestle or a food processor, combine the black peppercorns with the garlic.
Place the chicken strips in a large mixing bowl. Add the garlic-pepper mixture and the fish sauce, and stir to combine.
Cover the bowl, place in the refrigerator, and let marinate for 20 to 30 minutes.
Heat the vegetable oil over medium heat in a wok or skillet. When it is hot, add the chicken mixture and stir-fry until cooked through, about 3 to 5 minutes.
Stir in the sugar. Add additional sugar or fish sauce to taste.
The Glory of the Mortar (and Pestle)
Serve the chicken with mounds of Jasmine rice. Garnish plates with slices of cucumber and tomato.
