here is a simple recipe - just a snack (served with beer
1,0 - 1,5 litre of water for half a kilo of frozen shrimps pour into a bowl and leave to boil on a kitchen-range. when it starts boiling put into the water 6-7 pieces of black pepper, 3-4 bay leaves and salt about one tea-spoon. And boil it without shrimps in it for about 8 minutes to make the water spicy and steaming, then put unfrozen shrimps in it and boil for about 5-10 minutes after the water starts boiling again then leave with the unopened lid for about 10 minutes. Fish out the shrimps with a spoon and serve with milled black pepper. The packed frozen shrimps sold in shops are often half prepared already, I mean boiled, that's easier to use them.
also you may add shrimps into salads. Sorry, I'm so weak to make nice descriptions
