Fill a deep saucepan with water covering the lobster. Put into the water one tea spoon pepper grains and the juice from the lemon, together with the peel. Put the water on the hob plate to boil. Put the lobster into the boiling water and cook according to its weight. For the specified amount, the necessary time for cooking is 8 minutes. The time changes proportionally to the weight. If you use a cooking thermometer, the temperature of the meat in the center should be 80°С/180°F. Another sign that the lobster is ready is the change in its color - it should become dark red.
