Caesar Salad with Roquefort & Walnuts

Dressing:
4 flat anchovy fillets or to taste, rinsed and drained
4 garlic cloves, peeled
2 teaspoons sherry vinegar
2 teaspoons fresh lemon juice
1 teaspoon Worcestershire sauce
1/2 teaspoon dry mustard
1/2 cup extra−virgin olive oil

Walnuts:
2 cups walnut halves
3/4 cup confectioners' sugar
vegetable oil for frying
1/2 teaspoon salt
1/8 teaspoon cayenne pepper
4 heads romaine lettuce, the pale green inner leaves washed, spun
dry, and torn into bite−size pieces (about 12 cups)
1/2 cup Roquefort cheese, crumbled

Make the dressing: Mince and mash the anchovies with the garlic to
form a paste. Whisk together the anchovy paste, vinegar, lemon juice,
Worcestershire sauce and the mustard in a small bowl. Add the olive
oil in a stream, whisking, and whisk the dressing until it is
emulsified.

Make the crispy walnuts: In a saucepan simmer the walnut halves in
water to cover for 5 minutes, or until they are slightly softened.
Drain the walnuts and transfer to paper towels to dry completely.
In a bowl toss together the walnuts and the confectioners' sugar.
Deep fry the walnuts at 350F in batches for 1 to 2 minutes, or until
they are brown and crisp. Transfer the walnuts as they are fried with
a slotted spoon to a baking sheet and season with salt and cayenne
pepper. Cool.
