Pour the olive oil into a wide, heavy-bottomed frying pan. Then add the chile and garlic and, over moderate to low heat, to infuse rather than to color, fry for 2 minutes, stirring all the time. Then turn the heat to high, add the shrimp, and stir-fry them for another 2 minutes or until they turn pink and are just, delicately, cooked; you want the flesh to stay tender. Pour in the white wine and let it bubble up. You don't want a liquid puddle around the shrimp, just enough wine to let the juices ooze into a winy sauce. Another minute or so should do it. Season with the salt, if necessary, and then turn into your bowl and sprinkle with parsley. Eat with some good hunks of baguette. I eat these carapace, head, and all: one of the reasons I designate them for solitary dinner.
If you want, you can add a tablespoonful or so of brandy before throwing in the wine.
