Potato, Celery, and Gruyère Pie
Try some thin-sliced fennel instead of some of the celery. You'll need a total of one-and-a-half cups of the sliced vegetables.
Pinotage is a grape unique to South Africa. It makes a soft, juicy, berry-flavored red wine with smoky accents akin to Syrah. A Pinotage will be lovely with the Gruyère in this dish.
