What ritual, involving Calvados, occurs between courses during a lavish meal in the Normandy region?

Answer

The trou Normand (Norman hole).

Calvados, the apple brandy originating from the Normandy region, is famously incorporated into a specific dining ritual known as the trou Normand, or the Norman hole. This practice involves drinking a small measure of the spirit not at the end of the meal, but specifically between courses. The intention behind this consumption is not to conclude the dining experience, but rather to serve as a stomach 'kick start' or palate cleanser to prepare the diner for the subsequent course, highlighting a unique aspect of regional culinary etiquette contrasted with the typical digestif consumption after the final course.
