What is the main ingredient in Italian cookies Ricciarelli?
Ricciarelli are dense, chewy Italian almond cookies originating in Siena. In this type of cookie, you fold almond flour and icing sugar into whipped egg whites, and you leave the shaped cookies on the baking sheet for a while to dry out before baking in order to form a little crust on the outside.
They are typical of Siena, where they are usually enjoyed during the Christmas season. They are covered with icing sugar, with a soft heart that melts in your mouth, fresh and moist, with a distinctive aroma of bitter almonds.
