Always Measure Your Pasta Before Cooking

It is always better to measure your pasta before cooking to avoid wasting food. Use a food scale to measure the pasta.

One serving of pasta equals one-ounce uncooked pasta, which is also the recommended quantity for a person.

A food scale works best for all pasta shapes: spaghetti or elbow pasta. Alternatively, you can also get a pasta measure, which is a tool that has holes in it for measuring the portion size.

All you need to do is fill the holes for the required serving, and you are good to go.

Pasta measures are inexpensive and especially work well with strand pasta.

If you do not have a food scale, you can use a measuring cup to get the correct quantity needed. But it is trickier as the measurement may vary according to the shape.

If you want to make one serving of pasta for shapes such as rotini, shells, penne, elbow, and cavatelli, then you should take ¼ cup of these dry pasta shapes.

The rule of the thumb is that one serving of uncooked pasta equals ¼ cup, whereas one serving of uncooked pasta is ½ cup.

Resist the Temptation to Empty the Whole Box

Did you know that most dried pasta is made of only two ingredients? Any guesses?

Well, it is fairly simple. Semolina flour and water.

Because dried pasta does not contain eggs, it is quite easy to prepare. Semolina flour and water are made into a paste and pushed through a mold.

It is then cut into the desired shapes dried at a low temperature and stored.

do not empty box

Fresh pasta, on the other hand, is often made with eggs and generally has more fat and cholesterol.

We know that you might feel the urge to empty the whole box into boiling water, but you might end up making way more than required.

Do not worry uncooked pasta has long shelf life!

So, if you don’t intend to entertain more people, you will not need that much.

Generally, the pasta box you get from the supermarket is good enough to make four portions of pasta.

Tip: If a recipe mentions 2 cups of pasta, you should take the required amount of dry pasta.

If your pasta is made with white flour, it will increase twice its size after boiling in salted water.

On the other hand, if you go for whole wheat or gluten-free options, they do not swell up as much as the regular pasta. So, use more uncooked pasta.

When the pasta is made fresh, it doesn’t expand in size and requires much less water for cooking. Also, fresh pasta cooks pretty fast, i.e., in one to three minutes, so you need to keep an eye on it.

Stir it continuously so that it does not stick to the bottom of the pan.

On the other hand, dried pasta swells up when dropped in boiling water, it is easier to store, and has a longer shelf life.

Tip: Don’t rinse your pasta in cold water once it is cooked, as the sauce will not stick to the pasta making it less flavorful.

Avoid Using a Small Pot for Cooking Pasta

The size of the pot is often overlooked when boiling pasta.

However, it can make a huge difference, so always go for a giant pot when cooking pasta.

avoid cooking in small pot

It is best to have a pot that can hold up to five or six quarts of water. When you opt for a bigger pot, you don’t need to break the pasta if you are using strands such as spaghetti.

Moreover, as the pasta increases in size when cooked, it needs more space, or else the starch released upon boiling will make the pasta sticky.

There is one more reason to avoid using a smaller pot. The water temperature drops when you add pasta to a small-sized pot.

So, it takes a long time for the water to boil again, thereby making your pasta mushy.

Tip: If you don’t want your pasta to be sticky, stir the pot during the first two minutes of cooking.
