- 1/2 cup canola or vegetable oil
- 1/2 cup chopped fresh lemongrass (from bottom 4 inches of 2 stalks)
- 3 tablespoons chopped peeled fresh ginger
- 2 tablespoons fresh lime juice
- 2 teaspoons grated lime peel
- 4 7- to 8-ounce mahimahi fillets (each about 3/4 inch thick)
- Cook oil, lemongrass, and ginger in small saucepan over low heat 15 minutes to develop flavor. Cool completely. Strain oil into small bowl.
- Whisk 1/4 cup ginger oil, lime juice, and lime peel in medium bowl to blend. Season vinaigrette with salt and pepper.
