Place saffron in a small pot with the stock. Bring to a low simmer and reduce heat to keep warm and infuse the saffron into the stock.
Bring chops to room temperature and season liberally with Kosher salt and black pepper.
Heat a wide, deep skillet with a lid over medium-high to high heat with a turn and a half of the pan of oil (not extra-virgin, use a filtered, innocuous oil). Brown the chops on both sides and the edges and remove from pan. Add onions, garlic, chili flakes, orange or lemon zest or peel, thyme, rosemary and bay to the pan, reduce the heat a bit and cook to soften, 7-8 minutes. Stir in tomato paste until fragrant then add wine and raise heat again to reduce by half. Add saffron stock to the pan and bring to a bubble. Add chops, cover with the lid and braise at a low simmer for 30 minutes. Uncover and simmer to thicken, 15 minutes more.
Transfer meat to a warm platter. Whisk sauce up a bit and reduce if you wish to thicken a bit more. Chop mint and parsley and stir in herbs just before serving.
Meanwhile, place potatoes in pot and cover with cold water. Bring to a boil, salt water and cook to tender but not falling apart. Drain and return them to the hot pot. Add lemon juice and EVOO to coat lightly; toss and season with flaky sea salt to taste.
