What common allergen is present in the limoncello pie?

The presence of tree nuts in limoncello pie can be attributed to particular ingredients often used in its preparation. Pine nuts, for example, are sometimes included in pie crusts or as toppings, contributing to the flavor profile while also serving a decorative purpose. Additionally, limoncello itself may be made with nuts as part of a broader culinary style or influenced by regional recipes. It’s essential for individuals with nut allergies to be aware that tree nuts may be a common ingredient, as they can provoke serious allergic reactions.

In contrast, gluten, which is a protein found in wheat and other grains, would depend on the type of crust used in the limoncello pie. Dairy might also be present, but it is not inherently a standard component of all limoncello pie recipes. Peanuts, while a common allergen, are less likely to be included as they are not typically associated with traditional limoncello or Italian desserts in general. Understanding these nuances helps in allergy-aware food preparation and service, ensuring the safety of individuals with specific dietary restrictions.
