I've used dandelion & burdock mixed with stout and cacao as an injection for beef before now. It's good, you might find you want to add a little sugar to the injection though.
Everyone agreed It was an excellent result, even though no one could taste the Dandelion!
Ingredients:
1.15 Kg Joint of Pork
Method:
1, Unrolled the Joint and using a sharp knife cut several deep holes into it.
2, Seasoned with crushed garlic and salt (including the holes)
3 Poured Dandelion and Burdock into the holes and around the unrolled Pork
4, Rolled up the Pork and tied it with string then left for around 6 hours to marinate.
5, Cooked for 2 hours with the water bowl, smoking with hickory wood chips 3 times
6, Removed the water bowl and cooked for a further hour basting the Pork with honey for the last 15 min.
