Venison Tenderloin
The two small muscles inside the body cavity are the deer's filet mignon - the tenderest cut on the animal, traditionally eaten fresh in camp within days.
Inside the body cavity, tucked under the spine behind the last ribs, hide two slim muscles that do the least work of any on a deer - the tenderloins, venison's filet mignon. They're small (a pound-ish pair on a whitetail), sublime, and traditionally the hunter's immediate reward: pulled during field dressing or butchering and eaten within days, seared whole in a cast-iron pan while the rest of the deer hangs. If backstrap is the crown jewel, tenderloin is the private one nobody outside the family ever sees.
What it is
The psoas muscles along the INSIDE of the lower spine (the cavity side) - distinct from the outside backstraps, smaller, finer-grained, and the single tenderest tissue on the animal.
Why it eats this way
These muscles barely fire in life - stabilizers, not movers - so they carry almost no connective tissue at all. Texture is butter-soft at medium-rare; flavor is the mildest on the deer, a gateway cut for venison skeptics.
Breaking it down
Retrieve them EARLY - they dry-crust and discolor fast once the cavity is open (many hunters pull them at field dressing). A fingertip and knife-tip peel each one from under the spine membrane in a minute. Trim the thin silver, leave whole or portion once; there isn't much to engineer.
How to cook it
Whole-seared, always: ripping-hot pan or grill, 2-3 minutes per face to 54°C, butter-thyme baste, long rest, slice thick across the grain. Small enough to overcook in a distracted moment - this is a stand-at-the-stove cut. Medallions only from big-deer loins; whitetail tenderloins sliced raw-then-cooked just turn into gray coins.
Recipes that fit
Camp-classic cast-iron tenderloin with salt, pepper and butter (the traditional first-night meal); whole loin over coals; sliced rare on crostini with horseradish cream for the New Year's table; venison tartare or tataki for the confident - this is the cut clean and fresh enough to earn it, though eating venison raw carries pathogen and, in CWD-affected areas, prion risk that freshness does not remove, so do it only with meat from a healthy, tested animal.
Common mistakes
Forgetting them in the cavity (they ruin hanging there - retrieve day one), overcooking the small muscle by treating it like a backstrap section, marinating the mildest cut into tasting like the marinade, and saving them 'for a special occasion' so long they freezer-fade - the special occasion is the week you took the deer.
