One answer:
To preserve food. because they did not have refrigerators back then so they needed the spices for that.
Another answer:
Spices were used to flavor food, just as they are today. They were an important status symbol. Some European seasonings, such as onion, and thyme, were available, but people wanted things that were less ordinary, such as pepper, cinnamon, turmeric, and saffron.
Some spices may have been used to preserve food, but this is not a primary use, and does not work very well compared to other methods medieval people had. In those days, there were many ways of preserving food, including drying, salting, smoking, and fermenting. Those people who lived in colder climates even used cold storage areas, which was done from prehistory by using ice in cellars or caves.
Pepper is said to have been used as a preservative, but this is not the case. In fact fresh peppercorns rot very quickly unless they are preserved. There is a source link on this below.
Cinnamon can be used to inhibit bacterial growth when it is added to food, but it was too expensive to be used widely in this way.
Other things such as honey and even sugar can also be used to inhibit bacterial growth, and are much less expensive than imported spices would have been.
There is a source on medieval food preservation below. I did not see any reference to spices in it.
Yes, polyphony was used during the Middle Ages. We do not have any real idea of when polyphony was introduced, but the earliest texts describing it date to the Early Middle Ages.

The answer is probably "spices." "Salt" is another possibility.
Salt was the only thing they had to preserve food.
In the Middle Ages, the people used to salt meat to keep it fresh for later, as salt is a preservative and protects against bacteria, fungi, and insects. Therefore, they used to spice their food heavily when they ate it to camoflage the heavy and therefore unpleasant taste of the salt.
Spices were desirable to the wealthy because it gave them a chance to show off their wealth by adding new exotic flavors to food. Spices were imported from other countries and quite expensive so the low class did nit have much access to them.
