Excessive breathing creates low levels of carbon dioxide in your blood. This causes many of the symptoms of hyperventilation. Feeling very anxious or having a panic attack are the usual reasons that you may hyperventilate.
Ladyfingers (often called savoiardi and in British English sponge fingers) are low density, dry, egg-based and sweet sponge biscuits roughly shaped like a large finger. They are a principal ingredient in many dessert recipes, such as trifles, charlottes, as fruit or chocolate gateau linings and for tiramisu.
In a medium bowl, beat yolks with sugar and vanilla until smooth and light yellow. Fold mascarpone into yolk mixture. Set aside. Dip ladyfingers briefly in coffee and arrange 12 of them in the bottom of an 8x8 inch dish. Spread half the mascarpone mixture over the ladyfingers. Repeat with remaining cookies and mascarpone. Cover and chill 1 hour. Sprinkle with cocoa just before serving.
