20 wild-caught spot prawns or other shrimp (about 2 pounds)
1 1/2 cups cornstarch
Directions
Heat a small saucepan over medium heat and add the Grand Marnier to burn off some of the alcohol. Don’t reduce the liquid further. Once the alcohol fumes burn off, remove the pan from the heat immediately.
In a separate pan over medium-low heat, reduce the orange juice to a syrup until about ½ cup is left. Cool; then combine with the Grand Marnier and orange zest powder.
Chill until completely cold; then combine with the mayonnaise. Keep refrigerated until serving.
Heat the canola oil to 350°F in a Dutch oven over medium-high heat. Dredge the prawns in the cornstarch, shaking off any excess. Fry the prawns in small batches until crispy, about 2 minutes, and drain on paper towels.
In a large bowl, toss the hot prawns in the Grand Marnier mayonnaise to coat. Serve immediately.
