In the skillet, cook the bacon until crisp. Transfer bacon to a paper towel-lined plate. Discard all but 2 tablespoons the drippings.
Melt the butter with drippings in the same pan over medium heat.
Add the bell pepper, sliced scallion, and jalapeño. Cook until softened, about 5 minutes.
Add garlic and cook until fragrant, about 1 minute.
Deglaze the pan with sherry, scraping up any brown bits. Cook until sherry is nearly evaporated.
Add the corn, edamame, cream, and sugar. Simmer until the cream thickens, about 3 minutes.
Add the cooked bacon back to the skillet and stir to combine.
To serve, stir sliced scallion greens or herbs into the maque choux. Season with salt and pepper.
