Italians are more likely to have you over for lunch than to meet you for lunch. At least that's the case with Rolando. This is his cacio e pepe. Rolando founded the company Manicaretti, which imports all kinds of fine artisinal goods from Italy, the most well-known of which is Rustichella di Abruzo pasta — you know, the stuff in the pretty brown bags. For this pasta, he used their new primo grano line of pastas, made using grains from the first harvest. It has a subtle wheat flavor and slightly grainy texture that really comes to life in this very simple dish.
