Add the bacon and onions to a stock pot and cook over medium-low hear, stirring occasionally. Allow the onions to caramelize and the bacon to cook through.
Remove the bacon and onions to a paper towel lined plate and drain off the fat. Add the bacon and onions back into the pot along with the remaining ingredients for the bacon jam.
Allow to simmer until thickened, approximately 20 minutes, stirring occasionally.
Remove from heat and transfer to a container for storage.
Celery Root Puree
Add all of the ingredients to a stock pot and bring to a boil over medium heat. Cook for approximately 20 minutes, or until the celery root is fork tender.
Transfer all of the ingredients to a blender or food processor and blend until desired consistency.
Seared Scallops
Heat a large skillet over medium-high heat.
Remove the side muscle from the scallops and thoroughly pat them dry. Season with BBQ seasoning and salt.
Space scallops out in the pan, careful not to crowd. Cook the first side for approximately 1.5 minutes, or until you begin to see a golden brown crust form on the bottom coming up the sides. Flip over and cook the other side approximately the same time.
Scallops are done with they are seared golden brown but still have a spring to the touch.
To plate give a base of celery root puree, add the scallops, and top with bacon jam. Garnish with microgreens.
