What's for Lunch? A systematic ordering of foods in the Soup-Salad-Sandwich phase space
Madelyn Leembruggen, Caroline Martin

TL;DR
This paper applies principles of statistical physics to map out a comprehensive phase space of foods, classifying dishes into Soup, Salad, and Sandwich regimes, and resolving debates like whether a hotdog is a sandwich.
Contribution
It introduces a novel thermodynamic framework to categorize and analyze culinary dishes, providing a scientific basis for food taxonomy and phase behavior.
Findings
Identifies three distinct food phase regimes: Soup, Salad, Sandwich.
Maps out phase boundaries and co-existence regions in a 3D food phase diagram.
Concludes that a hotdog qualifies as a sandwich based on phase analysis.
Abstract
The statistical physics of phase transitions has been hugely successful at describing numerous natural, physical, and technological phenomena, and now a rigorous examination of the phase space of the culinary regime is likewise ripe for the picking. Despite great demand for the resolution of many scientific debates over the taxonomy of food, past attempts have failed to account for complex phase behavior and co-existence, and have thus left the public hungry for a more substantial theory. By applying the principles of statistical physics and thermodynamics, we here map out the complete phase space of all culinary dishes and find three distinct phase regimes: Soup, Salad, and Sandwich. We consider the effect of different state variables on these phase boundaries, as well as regions of co-existence and triple points. With this complete 3-dimensional phase diagram of all foods, we can…
