Long, think, ladyfinger cookies with an airy, delicate bite. Savoiardi measure about three inches long, 3/4-inch wide and 1/2-inch tall, ballooning outward slightly at both ends. A thin layer of sugar is sprinkled on top before baking. They are also known as biscotti al cucchiaio. Found on https://garrubbo.com/italian-food/glossary/
