The use of watercress gives this dressing peppery overtones, and the jalapeños are what really gives it some zing. It is good served over salad greens, as well as poured over tender-crisp cooked vegetables such as asparagus. You might even like it as a dip for carrots, jicama, turnip spears, and celery.

• 2 teaspoons dry mustard

• 1 tablespoon horseradish

• 1 teaspoon soy sauce

• 1/4 cup plain yogurt

Instructions

Combine all of the ingredients in a food processor or blender and puree. If the mixture seems too thick, add a few teaspoons of yogurt or ice water.
