Put orange juice in a small nonreactive saucepan and bring to a boil over high heat. Cook until reduced about 1/4 cup. Let cool to room temperature.
Put the butter, cool orange syrup, zest, jalapeno and sage in a food processor and process until smooth, season with salt and pepper. Scrape into a bowl. Can be made 1 day in advance and stored, covered in the refrigerator. Bring to room temperature before using.
Preheat oven to 450 degrees F. Remove neck and gizzard from the turkey and discard. Rinse the bird thoroughly with cold water and pat dry. Rub the entire surface with 1/2 of the butter. Season the skin and the cavity liberally with salt and pepper. Truss the turkey and place on rack in a large roasting pan.
Roast the turkey for 30 minutes, then turn the temperature down to 375 degrees and continue roasting for 1 1/2 hours or until the internal temperature reaches 165 degrees F, brushing with the remaining butter every 15 minutes. Remove the turkey from the oven and let rest for 20 minutes before carving.
