Mix Ginger, Herbs, Maple, bourbon, lemon juice, and a little oil, salt and pepper. Marinate the scallops in this mix for about an hour.
Peel and Cut Celery Root and Yams into 1 inch Pieces. Boil in salted water, in separate pans until soft (They cook at different rates). Drain both well. Place celery root in food processor. Pulse and mix until smooth, scraping down sides as needed. Add in the yams, continue processing until smooth and mixed well. Add in honey, butter, salt, and pepper. Place in a pan to reheat when needed.
Make the slaw: Julienne the vegetables and apples into 1 inch strips. Mix the cider vinegar, dijon, maple, salt and pepper, drizzle in the oil while whisking until the dressing becomes emulsified. Mix all ingredients together. Set aside until needed.
Heat a little oil in a saute pan over medium high heat. Remove the scallops from the marinade. Save the marinade. Sear the scallops about 2 minutes per side until golden brown. Add the marinade to the pan and cook another minute or two until the scallops are completely cooked. Remove the scallops and continue reducing the marinade until it becomes a glaze.
Reheat the yam/celery root mix. Place on a plate. Top with the scallops. Brush or drizzle the glaze over the scallops. Then top with the slaw. Serve immediately.
