Ingredients

 * 2 fresh beef (or other species) marrow bones, each at least 1 in long
 * water
 * 1 beer

Directions
In about a 2 qt pan, put the bones, and add enough water to cover the bones. Bring water to a boil; continue to boil for at least 10 min. (More time is ok, for a richer broth.)

Remove bones, and return any beef marrow to the liquid, along with any meat that you can get off the bones. Cool the broth to room temperature. Pour liquid only into 2-4 ice cube trays. Chop up the marrow/meat/gristle into little bits, and put them into each section of the tray. Freeze solid. Serve 2-3 cubes to your beardie on a very hot day. (Not too many if you made the broth very rich with extra bones or lots of marrow.)
