Beat the egg whites
with a drop of vinegar or lemon juice until fluffy. Slowly beat in the
sugar and the vanilla sugar. Melt the chocolate, add the nuts and stir
in the egg whites. Make little heaps on a greased oven tray and bake
the cookies 10-12 minutes at 175 degrees
Beacon Hill is
a 19th century neighborhood in Boston with a strong community feeling,
which is probably the reason why they bake this kind of cookies.
