Ají de langostinos is a traditional dish originating from Peru. It's usually made with a combination of shrimps, onions, oil, butter, yellow peppers, white wine, heavy cream, thyme, tarragon, salt, and pepper. The shrimps are boiled until pink, drained, and set aside.

The onions are sautéed in oil until soft and mixed with thyme, tarragon, yellow peppers, and white wine. The mixture is seasoned with salt and pepper and mixed with heavy cream in order to thicken the sauce. The shrimps are added near the end of cooking, and the dish is traditionally served with Peruvian-style white rice on the side.
