Alice introduces us to her group of friends. They've called themselves "JAMS" and we find out why in this episode. She begins telling us the story of how they got to know one another. Alice talks about la prima media. This is equivalent to the first year of middle school or the 6th grade of elementary school. The kids are about 11 or 12 years old.

It's the first day of school for our friends. In fact, it's their first year of middle school. The desks are set up for pairs of pupils, so choices have to be made as to where to sit and whom to share a desk with.

The class is welcomed by the principal as well as the art teacher. The surprise is that there will be a cooking course twice a week, as well as a group cooking contest. Who's on board? As we know, Joy is enthusiastic about it, but what about the others?

Alice, Joy, and Max want to win the contest, so they go around the neighborhood to find some traditional recipes. One stop they make is at the home of Joy's father's friend. The three classmates meet up with Stefano more than once, making them curious.

At the park, the kids try to come up with a recipe and they invite Stefano to take part in the project. One thing leads to another.

Joy has an interesting idea about where they can practice cooking. But it's a bigger challenge than she expected.

After the recap from the previous episode, the kids get to work on the cake they have to make in order to beat Davide and gain permission to use his kitchen for practice.
