This sauce is an example of not simply being able to substitute one ingredient for another. The spiciness of the arugula is far different than the sweetness of basil or dill. It took me about five tries to get the balance right in this recipe. Adding the Splenda softens the bitterness of the arugula without robbing it of the spicy flavor. Notice that there is no lemon juice in this recipe as there is in the Basil Pesto and the Dill Pesto.
Arugula
Known as Rocket (or Roquette) this is a member of the same family as cabbages and cresses. Arugula is pungent and spicy with a slightly peppery flavor. It is an essential ingredient in the Provençal mixed greens, mesclun.
Shop for arugula that is bright green with a soft texture. The younger leaves are not as spicy and I avoid very large leaves because they can be more bitter and tough.
