1 Coarsely chop the scallions.
2 In a shallow bowl, combine the cornstarch, salt and pepper. Dredge the chicken breasts in the seasoned cornstarch. Reserve the excess cornstarch mixture.
3 In a large skillet, warm 1 tablespoon of the oil over medium-high heat until hot but not smoking. Add the scallions and garlic and saute until the scallions begin to wilt, about 2 minutes.
4 Add the remaining 2 tablespoons oil to the skillet, add the chicken breasts and cook until golden all over, 2 to 3 minutes per side.
5 Stir the chicken broth into the reserved cornstarch mixture.
6 Add the broth mixture to the skillet. Add the curry powder, basil and raisins (if using). Bring the liquid to a boil, reduce the heat to medium-low, cover and simmer for 5 minutes.
7 Uncover the skillet and increase the heat to medium-high. Turn the chicken over, add the peas and cook, stirring, for 5 minutes longer.
