Heat a nonstick pan. Put in the concasse and stir over medium heat until all the liquid evaporates, about 10 minutes; turn up the heat for the last minute.
Add the capers, ginger, and garlic and cook another minute. Put in a bowl over ice to stop the cooking. When just cool, stir in the oil, salt, and pepper. Let sit 1 hour. Serve at room temperature.
