On this episode of “What Is X,” Justin brings back a seasoned veteran for one last job: he invites on his friend Seb Emina, former editor of the London Review of Breakfasts blog and author of The Breakfast Bible, to ask: What is breakfast? Now the editor-in-chief of The Happy Reader, Seb is no longer in the breakfast game—but when this podcast comes calling, one must answer. Together, Justin and Seb plumb their past and present as breakfasters, as post-Kelloggian subjects, as staunch opponents to the tyranny of brunch. Breakfast, that humble first meal of the day, is not just a meal, Seb asserts, but a mindset. Why is that? And what makes it such a universal, unifying experience compared to lunch and dinner? Listen in and you’ll also learn why cereal deserves a There Will Be Blood-style epic about its early days in Battle Creek, Michigan, what the Full English reveals about Brexit and the geopolitics of Western Europe, and the dishonor the BBC regularly casts upon breakfast. Plus: a peek into the secret language of Justin’s childhood.
