Beef bouillon cubes are a type of bouillon cube that is made up of dehydrated meat and/or vegetables, MSG, salt, and various seasonings. They are tightly compressed beef stock and are used to replicate beef stock. Beef bouillon cubes dissolve into liquids and typically require 1 cup of liquid or water to make beef broth. Bouillon cubes are used to add flavor to soups and sauces, as a substitute for stock, and to thicken and spice a curry. They come in a few different varieties, and beyond that, each brand puts its own spin into the cubes with an array of spices. The main varieties of bouillon cubes are chicken, beef, vegetable, and lamb, though the latter isnt as common as the other three. Bouillon cubes can also be dissolved in water to make broth. Some grate the cubes to create a rich powder that can be tossed with popcorn or sprinkled on food like salt. Beef bouillon cubes can be found in the spice or broth and stock aisle of the grocery store.
