Here’s what I put in the drip pan that was under the turkey to make the gravy. Turkey parts, onions, carrots, celery, chicken stock. The turkey parts were browned first and the pan deglazed with the chicken stock. Once the turkey was done the remaining liquids in the drip pan was poured into a saucier and reduced. Right before serving I added a roux. Most delicious gravy I’ve ever had.
