How to make the vinaigrette in a stand blender: Place the honey, lemon juice, cider vinegar, salt, garlic, onion, crushed red pepper flakes and black pepper in the blender. Cover and pulse on medium high until combined. On low speed, drizzle the olive oil in slowly in a steady stream through the top blending until emulsified and slightly thickened. Place into a mason jar and chill until serving. Shake well.
