What are three types of unripened cheese?

1. Feta: This crumbly, salty cheese is made from sheep's or goat's milk and is a staple in Greek cuisine.

2. Ricotta: This soft, whey cheese is made from the leftover whey after making other cheeses, primarily mozzarella. It's often used in sweet and savory dishes.

3. Queso Fresco: This fresh, mild cheese is popular in Mexican cuisine. It has a slightly crumbly texture and is often used in salads, salsas, and tacos.

While these are three common examples, there are many other unripened cheeses around the world.
