Red Cabbage Porterhouse Steaks with Herb Butter

To prepare cabbage: Place each cabbage on a cutting board, stem-side up. Using a large chef's knife, cut two 1-inch-thick slices from the center of each head. (Reserve the remaining cabbage for another use.)

Mash garlic and salt with a fork or the side of a chef's knife to form a paste. Combine the garlic paste with wine, oil, tamari, mustard, rosemary, brown sugar and 1/2 teaspoon pepper in a 9-by-13-inch baking dish. Dip the cabbage slices in the marinade to coat both sides, then place in a large sealable plastic bag. Pour the remaining marinade on top. Refrigerate for at least 8 hours and up to 1 day, turning occasionally.

To prepare herb butter: Combine butter, herbs and pepper in a small bowl. Scrape onto a piece of plastic wrap and shape into a 1-by-2-inch cylinder. Roll up in the plastic. Refrigerate.

Preheat grill to medium-high and preheat oven to 400 degrees F.

Remove the cabbage from the marinade (discard the marinade). Grill, turning occasionally, until very charred, 16 to 20 minutes total. Transfer to a large baking sheet. Bake until tender, about 15 minutes. Serve with the herb butter.
