"Our seven-year-old, Arwen, has been making this vinaigrette since she was five - she tastes it as she goes," says Levy Redzepi. "It's fresh and acidic and as good as the leaves. Frillice lettuce is crunchy but it's thin so it's like a perfect mix of cos and iceberg."
|01||Rinse the lettuce and put it in a bowl with very cold water to give a little extra crispness.|
|02||Meanwhile, mix balsamic vinegar and the mustards in a small bowl to combine, then while stirring slowly add the olive oil. Season to taste.|
