In this context, "salty milk and coins" is not a recipe; it is a mood. It is the taste of childhood mistakes, a Proustian madeleine for the scraped-knee generation.

It is, by all conventional standards, repulsive. Yet, it is this very transgression against culinary norms that gives the phrase its power. It is a collision of the organic (milk) and the inorganic (currency), the biological necessity of sustenance and the societal construct of value.

Outside of its internet-meme status, the phrase functions as a vivid, albeit unusual, descriptor for a specific flavor profile:

Represents the oxidation of iron. When blood (or sweat) touches the skin, oils react with the iron to create a distinct metallic scent similar to handling a pocketful of old pennies. Guy Drinks Menstrual Cup - Salty Milk and Coins Remix
