Ingredients

3 pounds medium new potatoes 

Coarse salt 

1 fresh bay leaf 

2 tablespoons Dijon mustard 

2 tablespoons grainy mustard 

1/4 cup Pickled Green Garlic 

6 tablespoons pickling liquid (from Pickled Green Garlic) 

3/4 cup extra-virgin olive oil 

2 tablespoons fresh tarragon leaves 

2 tablespoons fresh flat-leaf parsley leaves 

Preparation

Place potatoes in a large pot and add enough water to cover; generously salt water and add bay leaf. Bring to a boil over high heat and cook until potatoes are easily pierced with the tines of a fork, 15 to 20 minutes. Slice crosswise into 1-inch-thick rounds.

Preheat a grill: If using a charcoal grill, make a fire in your grill. When the charcoals are completely covered in gray ash, hold your hand about 5 inches above the grill grid; count how many seconds you can comfortably leave it there. When you can hold it there for 2 to 3 seconds, you have medium-high heat and are ready to grill. If you are using a gas grill, heat the grill for 15 minutes with the lid closed. Before beginning to cook, reduce the temperature by turning the knobs to medium-high.

Place potatoes on grill and cook, turning, until grill marks appear.

Meanwhile, in a large bowl, whisk together mustards, pickled green garlic, pickling liquid, and olive oil.

Transfer grilled potatoes to large bowl and gently toss to combine. Garnish with herbs and serve.
