1) Deer tastes like deer....but the backstrap is the mildest tasting cut. Most people, if served backstrap, would probably never know it was venison
2) Backstrap & tenderloin are also the most naturally tender portions of any large animal, as those muscles do little work in the course of the critter's life
3) Garlic gives it additional flavor.
Avoid handling any venison with methods that are labeled as "drawing the blood out", "taking the gaminess away", or "tenderizing". The best way to treat venison is like you would any other steak you've ever cooked. Dry cooking methods for already tender cuts and wet cooking methods for tougher ones that require more time to break down. It's a lot to type out in just one post, but keep an eye on these boards to learn a ton about great ways to cook game. The guy called Poser is a fantastic wealth of knowledge, and you can take whatever he posts on here as Gospel. He's done a helluva job applying non-typical cooking methods to game.
