Start by bringing a large pot of water to a boil for the spaghetti. While waiting for the water to boil, start another smaller pot of water for boil. Just enough water to cover the garlic cloves. Once the water in the smaller pot starts to boil, add in the garlic cloves and boil for 1 minute. After 1 minute, strain the water, and bring another round of water to boil, then add in the garlic cloves and boil for 1 minute. Repeat this process for a total of 3-4 times.
Once the water starts boiling for the pasta, season the water with sea salt, then add in the spaghetti. Cook as per containers recommendations.
Add the garlic cloves to a blender, and pour in the 1/2 cup of cool water, and 1/4 cup of extra virgin olive oil. Blend until smooth. Pour the contents into a medium sized pot. Do not turn on the heat. Sprinkle in cayenne pepper, small amount of chopped parsley, and a pinch of sea salt.
Once the pasta is done cooking, strain the water, and dump the pasta into the pot of the blended garlic. Stir the pasta to evenly coat it with the creamy garlic sauce. Serve on a dish, top off with another sprinkle of cayenne pepper, parsley and your choice of cheese.
