1) Cook a whole turkey. Bones, giblets, parsons nose, neck, gizzard, etc.
2) Roast your potatoes in some goose fat, along with some parsnips and a butternut squash. Leave the seeds in the squash.
3) Boil up your veggies. Cook whichever ones you like but always do sprouts even though nobody that is coming round for dinner actually likes them. But it's tradition, right?
4) Stick the whole lot in a food processor, blend until the turkey bones are very small and unlikely to make your elderly relatives choke too much.
5) When your ingredients are nicely blended, throw in some instant gravy granules and a few cranberries. Give it another blitz in the food processor.
6) Pour in half a bottle of Jack Daniel's, and give it a final spin.
7) Et voila! Christmas Dinner Smoothie. I think it satisfies your criteria.
