Here in Texas one finds beef shank in Caldo de Res (beef soup).
It is relatively easy to prepare at home and you can find lots of recipes on the web.
Some of the hispanic markets will have "kits" of the veggies trimmed and ready in a bundle to take home. All you need to add is the beef shank, water, and spices.
Many Tex Mex restaurants serve Caldo de Res on weekends along the the well known hangover cure Menudo.

Love mine. One could make a smoothies out of bricks with it if so inclined. It is used daily for smoothies, soup, dressing, etc.
One thing. It is a big kitchen appliance, almost 21 inches tall and relatively heavy. You really need a place to have it ready to go anytime. Not just a blender that one pulls out of the cabinets on occasion.
Give it that spot and it will become part of the daily routine.
Woo hoo! I am a chow hound lurker for many moons and finally made a post. I hope it was of use.
