Chatty, I usually make my gravy after doing a pot roast in the crock pot on top the stove in a sauce pan with the liquid from the crock pot. My crock pot doesn't bring the temperature up high enough to make a gravy thick enoigh to my liking.
I thought it would be interesting to attempt a gravy in the crock pot because I do like meat cooked in a gravy. Like Salisbury steaks, Swedish meat balls,Stews ect. I'm also a big fan for hot open faced sandwiches using left over roast or poultry. Slow cooking left overs in a gravy sounds very appealing to me. Crock pot casseroles slow cooked using a gravy for a sauce instead of using cream of mushroom or chicken soup just makes it more home made.
Honestly, lol. I like to try new things and using the Tapioca has sparked my interest and it's something I want to try.
