Now that is amazing. I can’t believe I never thought to do it. All the stress is gone!
Since it's just Hubby and I at home now, I'm not in the habit of cooking large meals anymore. Boy, when the holiday's come, I'm always scrambling around. This make ahead gravy is wonderful! Takes the "fire drill" effect away! :)
