Combine egg yolks, lemon juice, salt and red pepper in container of electric blender; set on high speed and process 3 seconds. Turn blender to low speed; add butter to yolk mixture in a slow, steady stream. Turn blender to high speed and process until thick.
Combine wine, vinegar, shallots,tarragon and pepper in a small saucepan; cook over high heat until almost all liquid evaporates. Add to mixture in blender and process at high speed 4 seconds. Serve over meat, seafood.
My preference is for clarified butter.
