Some soups are comforting because they hit hard. Gomtang is comforting because it does not. It does not arrive bubbling red. It does not smell aggressively garlicky from across the room. It does not ask you to brace for spice or richness or a long list of things happening in the bowl. It gives you broth, beef, and the kind of quiet warmth that starts working on you before you even notice you were craving it.
