Grilled Short Ribs and Lettuces with Mustard-Orange Dressing

Directions

1. 1.

   Stir red pepper flakes (if using), 1/2 cup marmalade, 2 Tbsp. mustard, 1 Tbsp. vinegar, and 1/2 tsp. black pepper in a small bowl.

2. 2.

   Place ribs in a glass baking dish; season all over with 2 tsp. salt. Pour marinade over and turn ribs to coat. Let sit at room temperature at least 15 minutes and up to 1 hour.

3. 3.

   Whisk garlic, 1/4 cup plus 2 Tbsp. oil, 1/2 tsp. salt, 1/2 tsp. pepper, and remaining 1 tsp. marmalade, 2 tsp. mustard, and 2 Tbsp. vinegar in a small bowl or measuring cup.

4. 4.

   Prepare a grill for high heat; oil grate. Grill ribs until lightly charred and crisp around the edges, about 2 minutes per side. Transfer to a platter, season with salt, and let rest 5 minutes.

5. 5.

   Drizzle cut sides of romaine and radicchio with oil, then season with 1 tsp. salt. Grill, turning occasionally, until lightly charred and warmed through, about 2 minutes for the romaine and 5 minutes for the radicchio. If using bread, grill alongside radicchio until lightly charred and warmed through, about 2 minutes per side. Transfer to platter with ribs.

6. 6.

   Pour dressing over charred lettuces and ribs; season with more salt and pepper.
