Heat a wok over high heat. Add the canola oil. Add the ginger and onions and saute until translucent, about 3 to 4 minutes. Add the garlic and the fermented black beans and cook for another 1 minute. Add the hoisin sauce, rice wine and chicken stock. Bring to a simmer and let cook for 5 minutes for flavors to combine. Combine the cornstarch and water to make a slurry. Whisk the slurry into the mixture and let simmer for 3 minutes. Add the clams and cover. Cook, covered, for 3 minutes, or until the clams begin to open. Remove the cover and add the bell peppers, snow peas and jalapenos. Toss the mixture together until all of the clams open. Remove from heat and garnish with scallions and cilantro. Discard any unopened clams.
