For an enhanced lavender flavor, consider steeping the crushed lavender in warm milk or oil for 30 minutes before adding it to the dry ingredients. Strain the milk or oil before using. To prevent the biscotti from becoming too hard, ensure they are completely cooled before storing them. If they do become too hard, try placing a slice of bread in the airtight container to soften them slightly overnight. Experiment with different flours such as almond flour or oat flour to create variations of this recipe. Adjust the liquid content as needed to achieve the desired dough consistency.
