Ingredients
2 pounds brussels sprouts (about same size, if possible), discolored outer leaves removed and a thin slice cut off from base
1 tablespoon whole-grain mustard
2 tablespoons white-wine vinegar
2 tablespoons olive oil
Coarse salt and ground pepper
Preparation
Fill a large bowl with ice water; set aside. Place a steamer basket in a large saucepan with a lid; fill with 1 inch of water. Bring to a boil; add sprouts, cover, and cook until easily pierced with the tip of a paring knife, 10 to 15 minutes (depending on size).
In a small bowl or liquid-measuring cup, combine mustard, vinegar, and oil. Season with salt and pepper, and whisk until combined.
Lift basket and transfer sprouts to ice water. Let stand until cooled, about 5 minutes. Drain well and pat dry; cut lengthwise through core into quarters. Serve sprouts drizzled with vinaigrette.
