✅ What This Tells Us (From a DIY Perspective)

1. It’s not just mustard + heat.
   The flavor balance comes from mustard, vinegar, sweetness (corn syrup), creaminess (oil + yolk), and spice depth (paprika, garlic, pepper).

2. The heat is subtle, not intense.
   Despite the name, it’s not overly spicy—more like a mild chili warmth, probably from paprika or a dash of cayenne extract.

3. The emulsification is key.
   Commercial sauces stay thick and glossy thanks to xanthan gum, oil, and egg yolk working together—this is often missing in copycat recipes.
