Fingerling Potato Salad

Cook potatoes in large pot of boiling, salted water until just tender when pierced with fork, about 15 minutes. Drain and cool slightly.

Meanwhile, slice 1 lemon into 1/8-inch-thick rounds. Combine sliced lemon, 2 cups water and 2 tablespoons kosher salt in small saucepan; bring to boil. Reduce heat and simmer until lemon slices are tender, about 10 minutes. Drain lemons, then very coarsely chop. Cut remaining lemon in half and squeeze out enough juice to measure 2 tablespoons. Mix chopped lemons, 2 tablespoons lemon juice, white balsamic vinegar and oil in small bowl. Coarsely crush cumin and coriander seeds using mortar and pestle (or wrap in foil and pound firmly using rolling pin). Mix seeds into lemon dressing. Season to taste with pepper.

Cut lukewarm potatoes lengthwise in half. Place in large shallow bowl. Mix in green onions and dill. Pour lemon dressing over and toss to coat. Season to taste with salt and pepper. Add arugula and toss gently.

Serve salad slightly lukewarm or at room temperature.
