How to Make It
In a large bowl, mix the Champagne vinegar with the minced shallots and season the mixture with salt and pepper. Let the shallots stand in the vinegar for 10 minutes. Meanwhile, using a sharp, thin knife and working over another bowl, cut the kernels from the ears of white corn.
Whisk the olive oil into the Champagne vinegar and shallots until blended. Add the arugula and toss with the dressing. Add the cherry tomatoes and the corn kernels and toss gently. Transfer the salad to a large platter, scatter the nasturtiums on top and serve.
