Which ingredient is not part of the Dijon Peppercorn sauce?

Dijon Peppercorn sauce typically consists of a base that includes Dijon mustard, peppercorns, and heavy cream. Honey is sometimes added to balance the sauce's flavors, particularly to add sweetness and depth. Heavy cream serves as the primary liquid component, providing a rich and creamy texture that complements the tanginess of the mustard. Peppercorns contribute the characteristic spice and heat to the sauce.

In contrast, olive oil is not a traditional ingredient in Dijon Peppercorn sauce. While olive oil may be used in various sauces and dressings, Dijon Peppercorn sauce relies on other components to achieve its intended flavor and consistency. Thus, recognizing the specific ingredients that contribute to classic recipes helps in identifying which elements do not belong.
