Crunchy Biscotti - Gluten Free, Nut Free and Top Allergy Free, Vegan. Biscotti are Italian cookies that are baked twice to achieve a supremely crunchy texture. They are perfect for dipping into a hot beverage, and are eaten year-round. You will commonly see them in cafes and they are traditionally made in a variety of flavours that may have dried fruit or nuts as well as spices and sometimes chocolate. However my version is free from the top 8 allergens, and is vegan and gluten free.
