As promised here is the recipe to the pickled shrimp. It has a lot of ingredients and each one is important. It is best if you make it about 3-4 days ahead to let it marinate. It makes enough for about 20 appetizer servings. It is so good.
6 pounds of medium cooked shrimp peeled with tale on
2 cups of tarragon vinegar
2 cups of sugar
2 tablespoons of dill
2 purple onions sliced thin
1 cup of lemon juice
2 tablespoons of sweet basil
2 tablespoons of minced garlic
1 cup of olive oil
1 cup of vegetable oil
2 teaspoons of Lawry's seasoning salt
2 tablespoons of red pepper flakes
2 tablespoons of parsley
6 small cans of sliced mushrooms
2 tablespoons of seasoning pepper (I use Monterey seasoning for steak)
1 small jar of capers (an option that I use)
Mix all together and marinate for several days stirring twice each day.
Serve cold with crackers.
