A delicious French dip sandwich, perfect for the working mom! Nobody, not even teetotalers, have been able to detect the presence of beer in this recipe, but it adds a wonderful flavor! French fries make a great side dish, and they are good for dipping, too.
For maximum tenderness and flavor, consider searing the rump roast on all sides in a hot pan before adding it to the slow cooker; this develops a rich crust through the Maillard reaction. When slicing the cooked roast, always go against the grain and aim for very thin slices to ensure each bite is tender. The slow cooker liquid is your precious au jus; for a more concentrated flavor, strain it, skim any excess fat, and reduce it slightly over medium heat on the stovetop. To enhance the French bread rolls, after buttering, consider a quick toast under the broiler for a minute or two until golden and slightly crisp, providing a better textural contrast and preventing sogginess from the au jus. While the recipe calls for beer, its primary role is to add depth and a subtle malty note, not a distinct beer flavor.
