1. Pulse first 4 ingredients in a food processor 3 or 4 times or until dough forms a ball and leaves sides of bowl. Divide dough into 8 portions, shaping each into a ball. Wrap each separately in plastic wrap; chill 1 to 24 hours.
2. Preheat oven to 375°. Cook pepper jelly in a small saucepan over medium heat, stirring often, 2 to 3 minutes or just until melted.
3. Roll 1 dough ball into an 8-inch circle on a lightly floured surface. Brush dough with 1 to 2 Tbsp. melted jelly; sprinkle with 2 Tbsp. pecans. Cut circle into 8 wedges, and roll up wedges, starting at wide end, to form a crescent shape. Place, point sides down, on a lightly greased parchment paper-lined baking sheet. Repeat procedure with remaining dough balls, pepper jelly, and pecans.
4. Bake at 375° for 15 to 20 minutes or until golden brown. Transfer to wire racks. Cool completely (30 minutes).
