Your cousin is a big food snob. He spends millions of dollars at hipster gourmet butchers and cheese shops. He is never not talking about a new restaurant that he "discovered." Guess what the perfect gift for him is? Best Made Salt & Salt Cellar ($45, Best Made Co).
I know you're thinking, "If someone gave me salt for a present, I would punch them in the goddamned face." But I guarantee that this foodie will LOVE it. The salt is hand-harvested in Oregon by Jaconsen Salt Co., and the cherry wood salt cellar will look great in his kitchen, amongst all of his ridiculously expensive olive oils.
