1. Wash artichokes well, cut off stem of each at base. Trim off top 1/3 of each leaf with scissors; place in large enamel covered pot. Cover with water, add oil, vinegar and spices. Cook over high heat until base of artichokes can be easily pierced with a fork, or a bottom leaf can be easily removed-about 40 to 60 minutes depending on size of artichoke.
2. Drain well, upside down, squeezing a bit to remove moisture. Spread leaves apart and remove choke with a spoon. Season with salt and pepper to taste. Prepare following vinaigrette sauce to serve in separate little saucers with the artichokes.
