This week, we sit down with Martin Kastner, the award-winning designer responsible for some of the most iconic objects in modern gastronomy. From Alinea’s game-changing serviceware to the now-legendary Porthole Infuser, Martin has spent his career reshaping how we experience food and drink — and the rituals around them. He takes us from his early days as a Czech metalsmith, to conceptual art school, and into a decades-long collaboration with Grant Achatz that helped redefine fine dining. We talk about the origins of his most influential pieces, the importance of “good friction,” designing objects that guide behavior, and so much more.
