A tangle of green and yellow summer beans is tossed with a tangy buttermilk-chive dressing and finished with basil, shallots, and sea salt.
Combine the buttermilk, egg yolk, lemon juice, and kosher salt in a blender. Blend on high speed, and then slowly stream in the olive oil.
Blend until smooth, about 1 minute. Transfer to a bowl and stir in the chives. Chill in the refrigerator for 1 hour before serving to allow the flavors to develop.
Cut the Romano beans and french beans into pieces. Bring a pot of salted water to a boil. Blanch the beans until tender, 4 to 5 minutes. Transfer to an ice bath and, when cooled, remove and reserve.
Slice the shallot very thinly on a mandoline.
Dress the beans and half of the sliced shallots with the buttermilk dressing in a medium bowl.
