Ingredients

1/4 cup (1/2 stick) unsalted butter, softened

2 teaspoons finely chopped fresh flat-leaf parsley

2 teaspoons finely chopped fresh chives

2 teaspoons finely chopped fresh tarragon

Coarse salt and freshly ground pepper

1 pound very small Yukon gold or other small waxy potatoes

1 bunch (about 6 medium) carrots, peeled

Preparation

Stir together butter, parsley, chives, and tarragon in a small bowl until smooth. Season with salt and pepper. Butter can be refrigerated, covered, up to 2 days.

Fill a medium pot fitted with a steamer insert with 2 to 3 inches water. Bring water to a simmer over medium-high heat. Add potatoes to insert; sprinkle with 3/4 teaspoon salt, and cover. Reduce heat to medium-low. Steam until potatoes are just tender, about 15 minutes. Add carrots; cover, and steam until vegetables are tender when pierced with a knife, about 5 minutes.

Transfer to a serving platter. Spoon about 2 tablespoons tarragon butter over vegetables. Serve immediately with remaining butter on the side.
