Haven't tried this yet, but it's on my to-do list. I'd like to experiment using whipped cream cheese in place of the yogurt, or adding some finely-chopped sun dried tomatoes. Sometimes I use recipes as a guide line & add the goodies I like.
Wash artichokes. Cut off stem ends and trim about 1 inch from top of each artichoke and about a fourth of outer leaves. Rub top of artichoke and trimmed leaves with a lemonwedge. Wrap in wax paper and microwave until tender and an inner leaf releases when gently pulled upon (approximately 6 minutes rotating once during the process).
Place upside down on a rack to cool. Gently spread center leaves apart and remove the choke with a spoon and discard. Chill if desired.
Bring 1 1/2 cups water to a boil in a saucepan. Add shrimp. Reduce heat and cook 3 minutes, drain well and rinse with cold water. Chill and set aside.
Combine yogurt and next 4 ingredients in a small bowl. Stir well. Spoon 1/4 cup yogurt mixture into the center of each artichoke. Arrange shrimp around upper edge of each artichoke, hanging over.
