Wash artichokes by plunging up and down in cold water. Cut off stem to within 1 inch of base. Remove bottom leaves and tough outer leaves of artichokes. Place artichokes, stem ends down, in an 11 x 7-inch baking dish; add water to depth of 1 inch. Cover with heavy-duty plastic wrap, and vent. Microwave at HIGH 10 minutes or until a leaf near the center of each artichoke pulls out easily. Drain. Remove fuzzy choke from center of each artichoke with a spoon.
Melt butter in a small saucepan; stir in garlic. Cook over medium heat, stirring constantly, until garlic is lightly browned. Add lemon juice and remaining 4 ingredients; heat just until hot. Serve as a dipping sauce with whole artichokes.
