Heat a large skillet over medium-high heat. Heat the oil and add the bacon. Cook until crisp, 2 to 3 minutes, and then add corn, letting the sugars develop and caramelize at the edges. Add the garlic, onions, bell peppers and jalapenos, and cook 2 to 3 minutes to soften. Add the stock, sugar, vinegar, Worcestershire and tomato sauce. Simmer to thicken the sauce, then add the edamame and stir in Sriracha to taste. Reduce the heat to low until ready to serve, adding a little more stock or water if the dish gets too thick. Garnish with scallions to serve.
