**Combine the ingredients**
In a mixing bowl, whisk together the harissa paste, yogurt (or your chosen creamy base), lemon juice, and garlic until smooth and well combined.
**Adjust the seasoning**
Taste the sauce and add a pinch of salt or more lemon juice if needed to balance the flavors.
**Chill (optional)**
For best results, let the sauce chill in the refrigerator for 15–30 minutes to allow the flavors to meld together.
**Serve**
Use the sauce as a dip, drizzle, or spread, and enjoy with your favorite dishes.
