Once every three/four weeks, me and DP do a roast. I take care of the meat and he does the vegetables. Last Christmas we went round to stay with my parents (in our support bubble); when we there we helped them cook the turkey on the day.
A few hours after getting back to our home, DP asked me why I hadn't just used shop bought gravy granules or the like. I explained (as I've tried to before) that it was traditional for me and my parents to make our own gravy - we boil the bones in a pressure cooker to make the stock. At Christmas I add the turkey neck, giblets, etc to the mix, as I don't like throwing them away when they can be used. When I've got the time I cook more for fun than just necessity, so I enjoy seeing what comes out of leftovers that might have otherwise gone to the bin.
Am I really the only one who makes their own gravy?
