Seared scallops are my current favorite appetizer, and while their cost can be rather exorbitant, you don't need more than 4 per person for a wonderful, filling appetizer. This vinaigrette balances their meaty flavor with a fresh zing and orange supremes can complement is beautifully with their sweetness. Thanks Chef John over at Foodwishes.
Dissolve sugar in vinegar. Add to blender. Add washed and seeded jalapeno, oil and mustard. Blend until smooth. Season with salt and pepper. Serve over seared scallops with supremed orange slices.
