I let some tilapia marinate in this for a day. It took some of the fishy taste away and gave a hint of lime, but no real strong flavor. I would have liked more kick.

Key West Marinade

3/4 cup reduced-sodium chicken or vegetable broth
2 tbsp chopped fresh parsley
2 tbsp fresh lime juice
1 tbsp dried onion flakes
1 tsp finely grated lime zest
1/4 tsp garlic powder
1/4 tsp ground black pepper

Combine all ingredients in a medium bowl and mix well to combine. Refrigerate until ready to use.
