- ½ cup sour cream

- ¼ tsp paprika
Directions
1. Make the Cajun Mustard Sauce

2. Sear the Tuna
- Coat tuna cubes heavily with blackening seasoning.

Pro Tips:
- Don’t Overcook: Tuna is best medium-rare (internal temp: 125°F).
- Substitutions: Use jumbo shrimp or salmon instead of tuna.
- Spice Control: Reduce horseradish for milder sauce.
