Carbonades Flamande is a favourite in Flemish regions of Belgium, made with their local dark abbey-style beers such as Leffe Brune or Brugse Zot Dubbel. Most will prefer to use onions in the recipe, but I used leek in mine to change it up a little bit as I have a family member who is intolerant to onion. It makes for a slightly different but welcome texture. As with all stews, it takes patience to cook, but is well worth it for the end result.
