There are more steps to making these skins into fine shoe leather, with the result of turning waste products into noble ones.

We move on to Biella, northwest of Milan, where the quality of the water contributes to the excellent quality of the woolen fabrics produced by the historical Zegna company.

Gratitude for the bounty of nature is a primary value for the Zegna Foundation. It might be helpful for the viewer to know that l'abito is a noun (think "monk's habit") meaning a gown or suit, but it is also the first person singular of the verb abitare (to inhabit, to live).

Tortona is an area of Milan, where steel mills stood previously. The huge structure turned out to be perfect for housing, once renovated, the Ansaldo workshop for the sets of Teatro alla Scala. The area has become very trendy and popular, especially during the Milan Fashion Week.

We get a glimpse of the spaces where a show takes shape, from sewing the costumes, to creating the sets and backdrops. When a model of a set arrives, the job of the team is to translate it into reality, into something big.

The founder of the Jonian Dolphin Conservation describes one of its projects: Ketos, Euro-Mediterranean center of the sea and cetaceans, based in Taranto.

The deepest part of the Mediterranean is located between Apulia and Greece. There, conditions are such that there is plenty of food for predators. With the "Researcher for a Day" program, the association gets precious help searching for cetaceans in these waters.

The bread from Altamura (in Apulia) is very famous among Italian bread connoisseurs. Beppe di Gesù, our host in this segment, comes from a long line of bakers. Breadmaking is so special that it's called l'arte bianca (the white art), because of the color of the flour.

Here we go with a new series with Anna and Marika. Each video will feature an oral quiz — just like in actual Italian schools — about a region of Italy. A separate cooking video will feature a recipe from that region. We start in the "heel of the boot": Puglia.

Anna gets grilled on Sicily by Marika. Oral quizzes are very frequently used in Italian schools. Grading is done on a scale from 1-10 for primary and secondary schools, and from 1-30 at the university level.

Anna and Marika are going to make a delicious recipe from Puglia. They explain what panzerotti are and the necessary ingredients and utensils for making them.

Anna and Marika complete the recipe and the resulting “panzerotti” look mouth-wateringly delicious.

In this video Anna and Marika show us how to cook the famous pasta dish named after the opera Norma by Vincenzo Bellini. The ingredients are few and simple, but there are some norms to stick with. ;)

Marika completes the recipe for "pasta alla Norma," and serves it up. It's evident that Anna thinks it's real good, too. In fact, she describes it as troppo buono (too good), a typical colloquial way to say "very, very good."

Anna is quizzed on Sardinia and can easily identify the capital and its major cities, its nuraghes (characteristic low towers), its cantu a tenore (traditional singing), but comes up short on providing the name of a typical Sardinian dish.

Marika and Anna assemble the ingredients and utensils to make this Sardinian speciality that's similar to ravioli.

In this phase, Marika and Anna roll up their sleeves and get their hands dirty. They start making the dough by hand, and are very excited about using their new pasta machine.

Here we are in the final phase of this delicious pasta recipe from Sardinia. This is the fun part, for sure.

It's time to talk about Calabria, a southern region with both sea and mountains. Let's hope Anna did some studying.

Anna and Marika provide the list of necessary ingredients for this Calabrese specialty. This recipe calls for sheep's milk ricotta. When you go to buy ricotta in Italy, storekeepers will ask if you want cow, sheep, or goat ricotta. You can also specify a mix.

All the ingredients are ready, and Anna and Marika go to work, making the ricotta ball mixture. They share with us a common saying about prezzemolo (parsley).

Anna and Marika form the Calabrian ricotta balls and cook them in tomato sauce. The ricotta balls can also be fried and served without sauce.

Let's see if Anna has studied one of the northernmost regions of Italy. It's a border region and as such, has some peculiarities.

You don't need much to make this recipe from the north of Italy. It's best with aged cheese, however, and even leftover rinds will do. Anna and Marika tell us about the ingredients and utensils necessary.
