There are lots of different ways to cook a lobster, here comes my favorite and easiest one, I call it lobster a la Ula:
Recipe is for 2 people:
2 lobsters 1.1/2 lbs each
2 liters of water
1 tsp. salt
1/2 tsp. black pepper
4 bay leaves
4 cloves of garlic with their skin, crushed
1 onion, cut in quarters
a few sprigs each of parsley, thyme, sage, oregano or any other herb you like
juice of one lemon
1 stick of butter
Put all of the ingredients except lemon zest and butter in a large pot and bring to a boil, cook for about 15 minutes, add lobsters head side down and cook for about 15 minutes at moderate heat, remove lobsters and put in colander to cool slightly, sautee butter in pan until slightly brown, add lemon juice and lemon zest, cut lobster tails open and drain any water that might be in the cavity, remove flesh and dip into butter. This goes well with steamed vegetables like asparagus, broccoli, carrots and potato or sweet potato wedges.
If you like spice, you can cook the lobster with a few hot peppers in the broth.
