Porchetta

Directions

1. 1.

   Put belly skin side down; arrange loin in center. Roll belly around loin so the short ends of the belly meet. If any of the belly or loin overhangs, trim meat. Unroll; set loin aside.

2. 2.

   Toast fennel seeds and red pepper flakes in a small skillet over medium heat until fragrant, about 1 minute. Tip spices into a bowl; let cool. Finely grind spices in a spice mill and transfer to a small bowl, along with the sage, rosemary, and garlic; set fennel mixture aside.

3. 3.

   Assemble porchetta according to steps 1-5.

4. 4.

   Refrigerate roast, uncovered, for 1-2 days to allow skin to air-dry; pat occasionally with paper towels.

5. 5.

   Let porchetta sit at room temperature for 2 hours. Preheat oven to 500°F. Season porchetta with salt. Roast on rack in baking sheet, turning once, for 40 minutes. Reduce heat to 300°F and continue roasting, rotating the pan and turning porchetta occasionally, until an instant-read thermometer inserted into center of meat registers 145°F, 1 1/2-2 hours more. If skin is not yet deep brown and crisp, increase heat to 500°F and roast for 10 minutes more. Let rest for 30 minutes. Using a serrated knife, slice into 1/2" rounds.

6. 6.

   1. Set belly skin side down. Using a knife, score the belly flesh in a checkerboard pattern 1/3" deep so roast will cook evenly.

7. 7.

   2. Flip belly skin side up. Using a paring knife, poke dozens of 1/8"-deep holes through skin all over belly. Don't be gentle! Keep poking.

8. 8.

   3. Using the jagged edge of a meat mallet, pound skin all over for 3 minutes to tenderize, which will help make skin crispy when roasted.

9. 9.

   4. Turn belly and generously salt both it and loin; rub both with fennel mixture. Arrange loin down middle of belly. Top with orange slices.

10. 10.

    5. Roll belly around loin; tie crosswise with kitchen twine at 1/2" intervals. Trim twine. Transfer roast to a wire rack set in a rimmed baking sheet.
