In a medium mixing bowl, combine tahini, lime juice, chili powder, smoked paprika, garlic powder, and salt. Whisk until a creamy mixture forms.

Gradually add water, one tablespoon at a time, whisking after each addition until you achieve a smooth and pourable consistency.

Taste the sauce and adjust the seasoning as needed, adding more chili powder for heat or lime juice for brightness.

Serve the sauce immediately or store it in an airtight container for later use.
