Thanks. The replies reinforce what I was thinking already. But to answer your specific question: it's my belief that the drippings just add good 'ole flavor. This is what I don't want to miss.
I am making a sauce which recipe calls for some beef drippings/grease. I know that this will add some flavor, but i don't want the calories, etc. What can I substitute for this? Organic shortening? Anything else? Thanks.
