If you want to fit in with the locals in Italy, eat your pasta with only a fork, not a fork and a spoon.

If possible, serve warm pasta in warm, shallow bowls instead of on dinner plates. The sides of the bowl aids in turning pasta noodles on the fork. You don’t have to use the spoon. Twirl the pasta with a fork keeping the fork tip in contact with the plate.
Some also feel that cutting spaghetti into small bite-sized pieces is not proper. However, it should be fine to cut the strands to shorten slightly before twirling.
Slurping pasta is the only method that is never proper.

During the 18th and 19th centuries, the ordinary people ate spaghetti with their hand. The addition of sauce made pasta a messy dish to eat with the hands and an instrument that was as curious as it had been neglected until that time, soon began to appear on the tables of the middle class: the fork.

That implement had been around in various forms for several centuries and had filled various functions at the tables of refined and snobbish households throughout Europe. However, its use as a standard utensil had not been established. The fork was put out on the tables of a restricted number of nobles in order to impress guests rather than assist them in eating.

The spread of the practice of eating pasta dressed with tomato sauce led to the adoption of the fork as an everyday utensil. The new standard implement had four curved tines, the length of which was no more than twice their combined width.

When the fork was invented, pasta became food fit for royalty as well, because they could now eat it without a loss of dignity.
