A fragrant soup that lets the flavor of the vegetables shine through.
Parsnips contribute sweetness and texture to this fragrant soup. I used water, not stock, and the flavor of the vegetables shines through.
02Blend the soup in batches in a blender (cover the top with a towel and hold it down to avoid hot splashes), or through a food mill fitted with the fine blade. The soup should be very smooth. Return to the pot. Stir and taste. Adjust salt, add freshly ground pepper, and heat through. Serve in small bowls or espresso cups with a drizzle of yogurt swirled over the top and a sprinkling of tarragon.
