I learned you should never use hickory wood when grilling shrimp.
the Hickory wood was great for salmon, steaks and sausages this past summer. But, while the texture of the shrimp came out absolutely perfect, the shrimp really sucked up the hickory flavor just too much. It had the perfect texture of grilled shrimp, but it tasted like wood - keeping in mind I had used a rub on the shrimp AND had a tomato alfredo sauce. Neither the rub nor the sauce cut the wood flavor down. The shrimp completely soaked up the wood flavor and let it overpower everything else.
I killed two pounds of shrimp in this disaster.
Learn from my mistake. Don't ever grill shrimp using hickory wood. From now it, it's gas grilling or in the frying pan for me!
