Chef Tips for Perfect Spicy Cajun shrimp cold pasta salad
Use these chef tips to perfect your Spicy Cajun shrimp cold pasta salad every time you make it.
- Chill components quickly by running cooked pasta under cold water and refrigerating shrimp immediately, which preserves texture and keeps the dressing from breaking.
- Season aggressively on the shrimp but keep the pasta light, since the dressing will carry spice evenly through the salad.
