Notes
Description of the Finished Sauce
A creamy, off-white sauce flecked with black pepper and horseradish, tangy on the nose with a gentle heat and a clean, bright finish that cuts through rich smoked poultry without overpowering it.
Texture & Thickness Tips
For a dippier/drizzlier sauce, whisk in 1–3 tbsp cold water or buttermilk until it coats a spoon but drips in a steady ribbon.
If it thickens after chilling, whisk in 1 tbsp liquid at a time to loosen.
Pro Tips
Sandwich magic: Toss warm shredded smoked chicken with this sauce for a tangy sandwich filling (great with pickles).
Pepper pop: Use coarse cracked black pepper for speckled look and bigger bite.
Brighten it: A pinch of lemon zest adds fresh aroma without thinning.
Serving Suggestions
Drizzle over smoked chicken halves, turkey breast, or grilled fish.
Use as a wing sauce (toss right after the cook).
Thin slightly for a coleslaw dressing or potato salad binder.

Texas Twist: Stir in 1–2 tsp finely minced pickled jalapeño or 1 tbsp jalapeño brine.
