2 medium cucumbers
1/2 cup salted roasted cashews, coarsely chopped (2 ounces)

2 teaspoons lemon juice, juice
1/4 cup extra-virgin olive oil
1/4 cup coarsely chopped flat-leaf parsley
1/8 teaspoon sea salt

1 teaspoon cumin seeds
2 tablespoons minced seeded serrano chile

1/2 teaspoon kosher salt
1-1 1/4 pounds dry sea scallops, (see Note), tough muscle removed

Preparation
1.To prepare salad: Peel and seed cucumbers; quarter lengthwise and slice 1/4 inch thick. Combine the cucumbers, cashews, scallions, lemon juice, oil, parsley and salt in a large bowl.
2.To prepare scallops: Toast cumin seeds in a small skillet over medium heat until fragrant, about 1 minute. Transfer to a cutting board and let cool, then coarsely chop. Combine the cumin seeds, chile, pepper and salt in a small bowl. Rinse scallops, pat dry and rub with the spice mixture. Thread the scallops onto four 12-inch skewers.
3.Preheat grill to medium-high. Oil the grill rack. Grill the scallops until cooked through, about 4 minutes per side. Carefully remove the scallops from the skewers. Serve warm with the cucumber salad.
