Here are my notes, i have done a couple and the results have been good
Porchetta
Pat dry before seasoning
Baking powder in the seasoning to help crisp
Let sit in fridge wrapped in pink butcher paper 10 to 12 hours to draw moisture out after seasoning
Direct on rotisserie
Add drip tray 20 to 30 minutes in, or once it flares up
385 degrees until 115 degrees internal temp
Then raise temp to 500 for 20 minutes to crisp
Or
The Wilbur Method, i found that on this forum
“Roll it and dust with baking powder and salt (the Wilbur method). Baste with the rendered fat every 30 minutes. Increase heat to 400 until the skin crisps. Outside crispy like a chip and inside could be eaten with a spoon.”
