Ok, so this more than just boiling water. It's about making spaghetti with homemade marinara sauce. My assumption is, you probably already know how to boil water and cook pasta. However, there might be someone in the crowd who doesn't understand the process, so let me break it down for you.
Here are some simple tips for boiling water and pasta
Pasta with Marinara Sauce
Bring a pot of water to a boil. As you are waiting for the water to boil, begin making the sauce.
Place the olive oil, red pepper flakes, and garlic in a cold sauté pan or skillet. Place the pan on the stove over medium heat. Doing this helps infuse the flavors of the red pepper flakes and garlic into the oil. Once the garlic begins to sizzle, add the tomato paste. Stir it around and cook for 1 minute. Add the red wine; cook for 1 minute. About half of the wine will cook off. Add the tomatoes and season with salt and pepper (about ½ teaspoon of each). Reduce heat to medium low and simmer for 10-15 minutes. Taste and adjust the seasonings. At this point, you have a choice to leave the sauce chunky or puree it for a smoother sauce. I chose to puree half of the sauce using a hand blender (do this in a deep bowl, to prevent wearing the sauce). You can also use a regular blender or food processor. Once I pureed the sauce, I returned it back to the pan and added the basil.
Once the water begins to boil, add a hefty pinch of salt to the water and add the pasta. Cook pasta according to package directions, but reduce the cooking time by 1 minute.
Drain the pasta, reserving a ½ cup pasta water. Add the pasta and pasta water to the sauce. Cook for 2-3 minutes over medium low heat. Serve with bread and parmesan cheese.
