For some reason, it has become relatively common knowledge in the US that the one thing you should always do when boiling water for pasta is drizzle in olive oil to prevent the pasta from sticking. And it's just downright wrong — at least, according to Italians.
Italians often use olive oil (specifically extra virgin olive oil) to dress cooked pasta. This can be as simple as a liberal drizzle over a finished pasta dish, but the most famous example is pasta aglio e olio, or pasta with olive oil and garlic.
Olive oil is said to prevent the pot from boiling over and prevent the pasta from sticking together. But, the general consensus is that it does more harm than good. It can prevent the sauce from sticking to the pasta.
Contrary to popular myth, adding oil into the water does not stop pasta sticking together. It will only make the pasta slippery which means your delicious sauce will not stick. Instead, add salt to the pasta water when it comes to the boil and before you add the pasta.
Italians tend to use olive oil for both cooking and seasoning.
DON'T SPILL THE OLIVE OIL
Some Italians believe that spilling olive oil will bring bad luck. This belief likely originates from the fact that the oil was an expensive commodity in the past. Let's be honest, it was probably regarded rather foolish for someone to waste such an pricy product.
Olive oil has a lower smoke point-the point at which an oil literally begins to smoke (olive oil's is between 365° and 420°F)-than some other oils. When you heat olive oil to its smoke point, the beneficial compounds in oil start to degrade, and potentially health-harming compounds form.
Most veteran pasta makers add oil to their pasta water to prevent the noodles from sticking together, or to keep the water from boiling over.
The flavor compounds in olive oil are delicate and will evaporate when heated. Heating olive oil does not damage the health benefits but it will make the olive oil lose some flavor. Some people consider this to be a good thing as they do not want their foods to taste like olive oil.
Even though olive oil has a lower smoke point than other cooking oils, quality extra virgin olive oil is still a good option option for cooking. The main thing that happens when olive oil is heated is that some of the flavor compounds will evaporate.
This is very dangerous. Water and oil do not mix. The water expands and at some point has to find a way past the oil. Like the trapped magma of a volcano, the boiling water can suddenly explode past the oil and blow bits of hot oil everywhere.
A small amount of fat—extra-virgin olive oil or butter—is essential to good pasta sauce texture. Without fat, you have at best watery sauce (nobody has ever said, "Waiter, my pasta is not quite wet enough"), and at worst sauce that over-thickens with starch alone and takes on a pasty texture.
The ancient Greeks imported the tree around 1,000 BC and since then Italians have used olive oil for dressing, cooking, and preserving food – as well as in medicinal and beauty treatments.
Sure, Italians boil pasta in water, but that's not the only way they prepare Italy's fabulously versatile ingredient.
Do Italians rinse pasta after cooking it? No, they don't. Italians usually don't rinse pasta after cooking it because the starch released is useful for binding the sauce. In many first course recipes, in fact, you have to add a little cooking water to mix the condiment with the pasta.
3. Salt the water – any Italian will tell you, always salt the pasta water. It is recommended to use at least 1-2 TBSP salt per 4-5 quarts water, to season the noodles while they cook.
The idea derives from the fact that oil, a slippery substance, once poured into the water for pasta then comes in contact with the pasta itself, so it greases and insulates each and every spaghetti or piece of pasta while cooking, preventing it from sticking afterward.
In fact, starting your pasta in cold water has a myriad of benefits: It takes less energy to heat, it takes less time since the noodles come to a boil with the water, and you end up with concentrated starchy cooking water that gives a silky, creamy finish to pasta sauces.
You must salt your pasta water.
In The Essentials of Classic Italian Cooking, Marcella Hazan had this to say about salting pasta water: "For every pound of pasta, put in no less than 1 1/2 tablespoons of salt, more if the sauce is very mild and undersalted. Add the salt when the water comes to a boil.
Benefits of adding olive oil in pasta water
The best choice is to add 1 teaspoon of Italica Olive Oil. This will keep the pasta from sticking while cooking and will also improve the flavor and texture. Pasta and oil are the perfect combination to help regulate intestinal transit.
Not just cooks, everyone in Italy will salt the water! Yes, not only cooks but everyone. You put salt before the water boils. It's something you learn as a child, the perfect amount of salt for the water, and we do it automatically.
First of all, it can be expensive. Plus, it has a relatively low smoke point, which, according to food scientist Harold McGee, is the "temperature at which a fat breaks down into visible gaseous products." That breakdown can ruin the taste of foods.
