Show Notes

In the 1980s, a low-sodium diet was seen as the gold standard for healthy behavior. In 2026, salt has been repackaged as “electrolytes” and is now cast as a core component of wellness. How did we get here?

Also, an important correction: One pound of butter to one pound of potatoes is Joel Robuchon’s recipe.
