In the medium bowl, stir together the wine and cornstarch. Add the chicken and mix well.
In the small bowl, stir together the sugar, vinegar, soy sauce, orange juice concentrate, and orange zest (optional).
In the wok, heat 1 tablespoon of canola oil over medium heat, until the wok is hot but not smoking. Add the snow peas and cook while stirring just until they turn dark green, about 30 seconds. Remove to a platter, spreading them around so they aren’t layered on top of each other. You want them to stop cooking.
In the wok, heat the remaining canola oil with the peppers. If using dried chiles, cook until they turn dark brown, almost black. Discard. If using sliced jalapenos, cook until the edges turn dark, then remove to a small bowl. Set aside for garnish.
Add the garlic and ginger and stir around the pan a few times until they sizzle.
Increase the heat to high and add the chicken. Stir for about 1 minute, then add the orange sauce and continue stirring for another minute or two. When the chicken is almost done, remove the garlic and ginger slices.
Add the mandarin oranges and stir gently to heat them and finish the chicken, about 1 more minute.
Spoon the chicken and oranges on top of the plated snow peas and serve immediately with steamed rice.
