Physicists stirred up controversy with scientific cooking tips in 2025

2025 was a year filled with groundbreaking discoveries in the world of food science. Two particular studies that gained widespread attention were the innovative recipes for cacio e pepe pasta sauce and perfectly boiled eggs. These studies, conducted by esteemed scientists, sparked both excitement and controversy within the culinary community.

In January, Ivan Di Terlizzi and his team at the Max Planck Institute for the Physics of Complex Systems in Germany unveiled their findings on how to achieve the perfect cacio e pepe pasta sauce. By introducing a small amount of cornstarch into the traditional recipe of black pepper, pecorino cheese, and water, the researchers were able to create a smooth and creamy sauce without any clumps. Despite the scientific rationale behind their discovery, the results were met with mixed reactions, especially in Italy, where the dish originates.

While some critics argued that cooking should be more about tradition and passion rather than scientific precision, the scientific community praised Di Terlizzi and his team for their innovative approach. Their work even earned them an Ig Nobel prize, a prestigious award that recognizes research that is both humorous and thought-provoking.

Meanwhile, in February, Ernesto Di Maio and his colleagues at the University of Naples introduced a new method for cooking boiled eggs that required careful attention and precision. By alternating the egg between pans of water at specific temperatures, the researchers were able to ensure that both the white and yolk cooked evenly, resulting in the perfect boiled egg.

Although some criticized the time-consuming nature of the recipe, it gained popularity online and even made its way onto international television programs. Furthermore, the scientific principles behind the egg-cooking technique are now being applied to other fields, such as the production of layered plastics.
