1 lb. shrimp, shelled & deveined
1/3 c. butter
1/4 c. cooked, sliced mushrooms
1 tbsp. catsup
1 tsp. chopped parsley
1/4 tsp. onion salt
1/4 tsp. garlic salt
Few drops Worcestershire sauce
Pinch monosodium glutamate
Parchment paper or aluminum foil

Cook shrimp 3 to 5 minutes in boiling salted water. Cut 4 heart-shaped pieces of parchment about 8" to 10" long. Place cooked shrimp in center of 2 separate paper hearts.

In a saucepan, melt butter and add remaining ingredients. Mix well and divide over shrimp. Cover each pile of shrimp and sauce with a paper heart and crimp edges all around to seal packets tightly. Place packets on cookie sheet and bake in 400 degree oven for 10 to 15 minutes until bag is puffy.

If shrimp have been cooked ahead of time and are chilled, add about 5 minutes to baking time to allow for thorough heating. Make an "X" shaped slit in packet with knife. Fold out points of slit and serve in the packet. Makes 2 servings.
