Relevés is French and, in a culinary context, is an adjective meaning "spiced" or "highly seasoned" (it is used in the plural form here, implying that there are several such dishes).
About 35 minutes into the episode, while on the plane with Will Graham (Hugh Dancy), Abigail Hobbs (Kacey Rohl) mentions that she and her mother were going to climb Eagle Point in Minnesota for her mom's birthday. In the first episode of American Gods (2017) (The Bone Orchard (2017)) around the 45 minute mark, Mr Wednesday is driving the Cadillac past a sign that says "Eagle Point". Both shows were written and produced by Bryan Fuller.
