Identify what smoked paprika is doing in your recipe: color + mild smoke (common), or spice layering (also common).
Pick the substitute that matches your constraints: choose chipotle powder for smoke + punch, or paprika + liquid smoke for a closer “paprika-only” taste.
Use the listed ratio as your starting point, then adjust after cooking if the substitute is too spicy or too salty.
For salty options (like smoked salt), reduce added salt elsewhere so the final seasoning stays balanced.
Taste at the end: add a tiny pinch more of the substitute for smoke, or thin the flavor with a neutral ingredient (like yogurt, broth, or oil) if it’s too intense.
