About Baci di dama
The biscuits are associated with Tortona in Piedmont. Italia.it links their name to the two halves meeting like lips, while Italian culinary sources trace the older Tortona style to hazelnuts.
The classic proportion is notably simple: equal weights of hazelnut meal, flour, butter and sugar create a short dough with little free water.
Cold handling is the technical control. Warm butter makes the tiny hemispheres spread; chilling shaped pieces lets them keep their rounded profile in the oven.
Chocolate should join, not dominate. A narrow layer is enough to hold each matched pair after the biscuits are fully cool.
