+          Mise en place is a French term that literally means “put in place.” It
+          also refers to a way cooks in professional kitchens and restaurants
+          set up their work stations—first by gathering all ingredients for a
+          recipes, partially preparing them (like measuring out and chopping),
+          and setting them all near each other. Setting up mise en place before
+          cooking is another top tip for home cooks, as it seriously helps with
+          organization. It’ll pretty much guarantee you never forget to add an
+          ingredient and save you time from running back and forth from the
+          pantry ten times.
