optional: mozzarella (if you like your béchamel sauce stringy

Mozzarella is a semi-soft, mild cheese traditionally produced from the milk of water buffalo (Bubalus arnesi) or, more commonly in modern production, cow's milk. Originating in southern Italy, particularly the Campania region, mozzarella is characterized by its white color, smooth texture, and high moisture content. The cheese is produced through a pasta filata (stretched curd) process, where curds are heated and stretched to create the cheese's distinctive elastic texture and stringy quality when melted. Traditional mozzarella di bufala possesses a delicate, slightly tangy flavor, while cow's milk versions are milder and creamier. The cheese's low melting point and ability to develop long, cohesive strands when heated distinguish it from harder cheeses.

Fresh mozzarella differs fundamentally from aged varieties; it is consumed within days of production and has a high moisture content (approximately 50-52%), while low-moisture mozzarella has been partially dehydrated for longer shelf life and develops greater elasticity.

Mozzarella serves as a foundational ingredient in Italian cuisine and beyond, most prominently in pizza, where its melting properties and stringiness are essential. It is a core component of classic Caprese salads (paired with tomatoes and basil), lasagna, baked pasta dishes, and gratins. In béchamel and cream-based sauces, shredded or diced mozzarella contributes a stringy, cohesive texture when incorporated into hot preparations, creating the characteristic "pull" desired in applications like baked pasta or gratinéed vegetables. Fresh mozzarella, typically sold as balls (bocconcini) or logs, is served cold as an antipasto or incorporated into salads, while low-moisture mozzarella is preferred for cooking applications due to its superior melting and browning characteristics. Mozzarella is versatile across Mediterranean and American cuisines, appearing in sandwiches, vegetable dishes, and cheese-forward applications.
