Storage: Store in an airtight container at room temperature for up to two weeks.
Serving Tip: For enhanced flavor, brush or pour a little extra anisette or anise-flavored liqueur over the cookies just before serving.
Variation: You can omit the lemon rind if you prefer a purely anise flavor profile.
Substitution: Sliced almonds can be used in place of hazelnuts if preferred or unavailable.
