Elk Tenderloin is a super tender cut of meat that is tucked inside the abdominal cavity under the spine. It can be cooked and served manyways: leave it whole and slice after cooking, stuff it with various savory ingredients, cut into thin steaks, or cut into thick medallion steaks.
Using a filet knife, cut the thin ends of the tenderloins off, about 1.5-2" from the ends. This will leave you with a more uniform piece to cut into medallions.
Then cut the middle halves into 2 or 3 pieces each, depending on the size of the tenderloin and your desired steak thickness. The medallions should be about 1-1.25" thick.
