## Summary

In their manuscript titled "Food-bridging: a new network construction to unveil the principles of cooking," Tiago Simas, Michal Ficek, Albert Diaz-Guilera, Pere Obrador and Pablo R. Rodriguez propose a new principle behind traditional cuisine known as the Food-bridging hypothesis. This hypothesis is compared to the food-pairing hypothesis using the same dataset and graphical models employed in a previous study by Ahn et al. (2011). The Food-bridging hypothesis suggests that if two ingredients do not share a strong molecular or empirical affinity, they can still become affine through a chain of pairwise affinities. In other words, there can be a path that connects these ingredients in a graphical model with the shortest path representing the strongest pairwise chain of affinities between them. Food-pairing and Food-bridging are different hypotheses that aim to explain the mechanisms behind traditional cuisines. While food-pairing focuses on intensifying flavor by mixing ingredients with similar chemical compounds, food-bridging aims to smooth out contrasts between ingredients. The authors observe that both food-pairing and food-bridging principles are observed in traditional cuisines. Based on their analysis, the authors identify four classes of cuisines according to their adherence to food-pairing and food-bridging principles. East Asian cuisines tend to avoid both food-pairing and food-bridging principles while Latin American cuisines follow both principles extensively; Southeastern Asian cuisines avoid food pairing but follow food bridging; Western cuisines follow food pairing but avoid food bridging. Overall, this study provides insights into the different mechanisms at play in traditional cuisines and highlights how these principles vary across different culinary traditions. The Food Bridging hypothesis offers a new perspective on ingredient combinations and could contribute to further understanding and innovation in cooking techniques.
