This is really good!

Ingredients
1/4 cup canola oil
2 -1/4 pounds baby brussels sprouts or regular brussels sprouts that are halved lengthwise
Salt and freshly ground pepper
1 stick (4 ounces) unsalted butter, cut into tablespoons and softened
2 tablespoons light brown sugar
1/4 cup Grade A pure maple syrup
2 tablespoons apple cider
1 tablespoon balsamic vinegar

Directions

Heat the canola oil in a very large skillet until shimmering. Add the brussels sprouts and season with salt and pepper, then cook over high heat without stirring until they are browned, about 2 minutes. Add the unsalted butter and brown sugar and cook over moderately high heat, stirring occasionally, until the brown sugar is melted. Add the maple syrup and cook, stirring occasionally, until the brussels sprouts are just crisp-tender, about 7 minutes. Stir in the apple juice and balsamic vinegar.

Using a slotted spoon, transfer the brussels sprouts to a bowl. Boil the cooking liquid over high heat until thickened slightly, about 2 minutes. Pour the sauce over the brussels sprouts and serve.
