I’m jumping in before getting to the end of the thread as I tend to get distracted but, back to your project.
I suggest butterflying a nice half pork loin, making up a “stuffing” of sautéed red onion, garlic, fresh fennel (sliced very thinly) maybe some Meyer lemon zest and some dried fruit like chopped apricot, or craisins etc. Lay it open on your board spread the filling on most of the opened loin, drizzle with some brandy or calvados, the juice of the 1/2 the lemon maybe a light dusting of breadcrumbs (Or not) roll, tie in the most even careful string work you can muster. Spit and spin! Roughly 45-60 minutes, it should be a delightful color, the fennel will offer a nice flavor and some chopped fennel fronds will be a pretty garnish! Serve with a drizzle of excellent EVOO and the rest of the lemon.
Some fava beans and a nice Chianti...
