At Benu, chef Corey Lee fries almonds and peels grapes for his compelling salad. At home, use roasted marcona almonds and unpeeled green grapes.
In a large bowl, whisk the verjus with the canola oil and season with salt and freshly ground pepper. Add the sliced endives, watercress, halved grapes and almonds; toss to coat and serve.
Verjus is the pressed, unfermented juice of unripe grapes. It is sweet and slightly acidic and is frequently used in place of vinegar. The bottles are available at specialty-food stores.
