What traditional pesto ingredient can arugula replace for a sharper flavor profile in culinary applications?

Answer

Basil

Arugula’s culinary versatility extends beyond raw salads, especially when heat is briefly applied, as its peppery edge softens nicely. When used in the preparation of pesto, arugula can serve as a direct substitute for the traditional primary herb. By replacing some or even all of the customary basil with arugula, a cook can create a homemade pesto that possesses a noticeably sharper and more complex flavor profile than the standard version. This substitution highlights arugula's strong taste, which means that even using modest amounts can significantly influence the overall flavor of the finished sauce or dish.
