Yes. While vinegar doesn’t actually “remove” the salt, the acidity provides a flavor “counterpoint” that tricks your taste buds. Adding a splash of vinegar (or lemon juice) distracts the palate and balances the harshness of the salt, making the dish palatable again. You still might be thirstier than usual. Add 1 teaspoon at a time of a mild vinegar (like Apple Cider or Rice Vinegar) and taste after each addition. Be careful—you want to balance the salt, not make the dish sour.
