Stir mixture with a spoon until mixture is thoroughly combined adding additional olive oil as needed. Mixture should be fairly thick but pourable.

Place shrimp in a large bowl and mix in about 2/3 of the sauce reserving 1/3 for serving. Stir until shrimp are evenly coated with the sauce about 2 minutes. Transfer shrimp to a resealable plastic bag. Refrigerate 2 to 3 hours. Cover and refrigerate remaining sauce.

Preheat an outdoor grill for high heat and lightly oil the grate.
