Pre-measure how much spaghetti you need for how many people you will need to serve.
Put a pot of cold water on the stove to boil
Pour some salt (1 tsp per serving) in the boiling water.
Break the spaghetti in half with your hands over the pot.
Carefully pour/place the spaghetti in the pot without causing any splashing.
Use a fork to stir the spaghetti for a few seconds, then allow the water to return to boil.
Turn the dial down to half-way (like a 5) or to minimum and allow the spaghetti to cook.
Stir occasionally, and allow the spaghetti to get soft.
Turn off the burner once the spaghetti is done.
Strain the spaghetti in a strainer and then put them back into the pot or a heat-resistant bowl
While the spaghetti is cooking, in a separate pan, pour in some pre-made sauce, cover with lid and set it to boil.
Turn the heat down immediately once the sauce starts to boil.
Mix some sauce into the spaghetti
Enjoy your meal!
