For best flavor, let the dip rest even longer (up to a few hours) so the mustard and spices can fully develop, and always taste again just before serving to fine-tune salt, acidity (a splash more vinegar), or sweetness (a drizzle of honey). Use full-fat sour cream and mayonnaise for the creamiest texture, and if you prefer a thinner dip, whisk in 1–2 teaspoons of milk or water at a time until it reaches your desired consistency. This dip keeps well covered in the refrigerator for up to 4–5 days, making it easy to prepare ahead for parties; just give it a quick stir before serving and pair it not only with pretzels but also with veggies, sausages, or soft pretzel bites.
