Tarator SaucePlace the walnuts, bread, garlic, lemon juice, stock, salt and pepper in a food processor. Whirl for a few seconds until smooth. Slowly add the oil in a stream through the container top opening while running the processor. The result should look like a mayonnaise.

Drain, let cool and separate the flowerets. Arrange on a serving platter. Pour tarator sauce over the cool cauliflower. Refrigerate. Serve at room temperature. Serves 6.
