Native speaker’s answer

Rebecca

A "building block" is a basic unit from which something is built or created. Thus, "curds ... became the building blocks of cheese" here means that curds became the basic unit or thing from which cheese was created. The speaker here is talking about the process of how people discovered cheese, calling the discovery of curds the "building blocks" (early basic unit) from which cheese was created. Ex: Sounds are the building blocks of language. Ex: Writing is one of the building blocks of culture.
