Add a bunch of peppercorns to a pestle and mortar and grind them to a coarse consistency.
Cook the green cabbage on high heat with algae oil, searing it for about 3-4 minutes on each side until it has a nice char.
Remove the seared cabbage and season it with a little salt on each side.
Place the cabbage into an oven preheated to 400 degrees Fahrenheit and roast for about 45 minutes for a large cabbage.
In the same pan, add butter, shallot, thyme, a little salt, garlic, and the ground peppercorns. Cook for a few minutes.
Add some wine, such as a rosé, and cook that down.
Add cream and a little more salt, then boil until the sauce is reduced to the desired consistency.
Once the cabbage is out of the oven and charred, douse it generously with the peppercorn cream sauce.
Sprinkle chives over the top to finish the dish.
