This is a great dish for a Fall or Winter meal. One of my
favorite ingredients, oxtails, were on sale and it’s hard to resist buying a
favorite ingredient on sale. Oxtails are mainly bone, but are full of gelatin and
together with tapioca starch, serves to thicken the sauce. The oxtails can
either be browned in a wok or Dutch oven the night before.
Star anise and cassia bark are the main spices used in this
dish. Cassia bark has a cinnamon-like flavor, but does taste slightly different
than “normal” cinnamon, and is sold as dried cinnamon sticks at Asian markets.
You can substitute regular cinnamon for cassia bark if you cannot find it. All
the soak-out cooker ingredients (except for the ginger and garlic) can be found
in the preserved/dried section of your local Asian market.
Tapioca starch is used to thicken the liquid and holds up
well in a slow cooker. I originally got this information from America’s Test Kitchen and they
use Minute Tapioca made by Kraft. I’ve used both the Minute Tapioca and plain
tapioca starch to thicken liquids in a slow cooker, and both work equally as
well. You can find Minute Tapioca in any grocery store and tapioca starch at
your local Asian supermarket. The tapioca starch is much more inexpensive than
the Minute Tapioca. Corn starch and other thickeners will break down and not
thicken during the long cooking times in a slow cooker.
Enjoy!
