1.- Cook the spaghetti. We put a handful of salt in a pan with plenty of water, and bring it to a boil. When it boils in a gulp, we put the spaghetti and let them cook for about 10 minutes.
2.- While they are cooking, we peel and chop the garlic cloves.
3.- In a large skillet, put a drizzle of olive oil, very soft fire. We put the chopped garlic and let them cook very soft fire for about 3 minutes. That do not catch color.
4.- We raise the heat and add the prawns now. We let cook 1 minute more. Enough time for both prawns and garlic to take on a golden color.
5.- Drain the spaghetti from the water, reserving two tablespoons of the cooking broth. Add the spaghetti to the pan, with the garlic and prawns. We added the cooking water we had reserved and some chopped parsley. We let cook one more minute, while stirring constantly. Spaghetti ready!
