La cacio e pepe It is one of the most iconic dishes of the Roman tradition, a triumph of simplicity and taste that, if prepared correctly, gives a velvety cream and an explosion of authentic flavors. But did you know that science has found the perfect method to make it without errors? Let's discover together the history of this dish and the scientific trick that guarantees its impeccable success.
Perfect Cacio e Pepe, its origins
The roots of cacio e pepe are deeply rooted in the ancient pastoral traditions of Lazio. The shepherds, forced to travel long distances across the vast countryside, had a limited number of provisions, favoring long-lasting and highly nutritious ingredients. Among these, dry pasta, aged pecorino romano and black pepper proved to be an ideal combination: practical, easily transportable foods that could provide sustenance without the need for refrigeration or elaborate equipment.
Over time, this rustic preparation has become an authentic symbol of Roman gastronomy, conquering the palates of generations thanks to its intensity of flavours and its irresistible creaminessAnyone who has tried making cacio e pepe knows how complex it can be to obtain a perfectly velvety consistency.

The main risk is the formation of lumps, rather than the desired creamy emulsion. This inconvenience is due to the very nature of pecorino romano, a hard cheese with a low melting point. If exposed to excessive temperatures, the cheese tends to separate into its fundamental components – fats and proteins – compromising the texture of the sauce and generating an inharmonious result.
La key to success It therefore lies in the meticulous control of temperature and the adoption of precise techniques, which allow a few essential ingredients to be transformed into a masterpiece of Italian cuisine.
The perfect solution and recipe
Recently, a team of physicists analyzed the cacio e pepe emulsion process and came up with a brilliant solution: use a starch gel to stabilize the sauce. But how does it work? Let's see it step by step.
Ingredients for people 2:
- 200 g of tonnarelli (or spaghetti)
- 100 g grated Pecorino Romano DOP
- 4 g of corn starch

Prepare the starch gel: Dissolve 4 g of cornstarch in 40 ml of cold water and heat the mixture until it becomes a gelatinous consistency. This gel will allow the sauce to remain stable and creamy.
Toast the pepper: In a pan, toast the whole black peppercorns to release their essential oils, then grind them freshly.
Cook the pasta: In a pan with a little water (so that it is richer in starch), cook the tonnarelli until they are al dente.
Manteca with the perfect sauce: Drain the pasta, leaving it slightly damp, and combine it with the starch gel and the pecorino cheese grated, stirring vigorously. Gradually add cooking water until desired consistency is achieved.
Serve with fresh pepper: Plate and garnish with a generous sprinkling of ground black pepper.
The starch gel improves the emulsion between water and cheese fats, avoiding lumps and ensuring a smooth and creamy sauce. Also, the trick of letting the pasta cool slightly before adding the cheese helps prevent the excessive heat from curdling the cream.
