Cacio e pepe

Cacio e pepe – simple and tasteful

Cacio e pepe is a very very simple dish which originally comes from Rome in Italy. The signification of the name is ‘cheese and pepper’ and that is exactly the two main ingredients. The trick is to use the pasta water which contains starch to melt the finely grated cheese and with the correct temperature you create a creamy sauce. Pure magic!

Cacio e pepe

There are several ways of making the sauce. You can mix pasta water and cheese to a creamy sauce. Or you can mix water, pasta and cheese together. It is all about melting the cheese and avoiding big rubber lumps due to a wrong temperature. A tablespoon of butter is your helper in this process.

It sounds so easy and yet I found it a bit hard to make the perfect sauce by mixing hard cheese and pasta water. I did get the lumps. But every time I melt the cheese when mixed with pasta and pasta water, I succeed.

A few words about the cheese

Originally, this dish was made with pecorino romano. It is quite salty and sharp which brings character to the dish. I have used pecorino sardo, another sheep milk cheese which also has a lot of taste but is more balanced in my opinion. You may also use parmigiano reggiano, grana padano or another matured cheese which can be grated finely.

Think about the cheese as you would do with spices – which taste of cheese do you want in the final dish?
