Tiramisù Charlotte
makes 1 6×3 inch cake
note: brew some strong coffee before starting, then allow it to cool.  If you are making ladyfingers, make those right after the coffee and let them cool as well.  You can always use store-bought.
for the savoiardi (ladyfingers):
makes 1 1/2 sheet pans of 4×1 inch savoiardi
ingredients:
3.5 egg yolks (1/2 yolk is approximately 1 1/2 teaspoons, or 0.3 ounce)
3 tablespoons sugar
3.5 egg whites (1/2 white is approximately 1 tablespoon, or 0.5 ounce)
pinch cream of tartar
4 tablespoons plus 1 1/2 teaspoons sugar
3/4 cup cake flour
directions:
Preheat oven to 350 degrees F.
Draw out 4×1 inch grids on two sheets of parchment paper; place them on two sheet pans, pencil or pen side down.
Have a pastry bag fitted with a 1 inch tip at the ready.
Place the egg yolks in a bowl with 3 tablespoons of sugar.
Place the egg whites in the bowl of a stand mixer with the cream of tartar.
Whip the egg yolks briskly (or with a hand mixer) until they become pale, thick, and double in size.
Meanwhile, whip the egg whites, slowly streaming in 4 tablespoons plus 1 1/2 teaspoons sugar once they begin to foam.  
Beat the egg whites until they hold stiff peaks.
Sift the cake flour over the egg yolks, but don’t mix in, then fold the egg whites into the egg yolk/flour until homogenous; be careful not to overmix.
Place into pastry bag and pipe out finger shapes, approximately 4×1 inch tall/wide.  (They will touch each other during baking.)
Bake for 8-10 minutes, until they are golden and puffy but not particularly hard. (They should not feel raw or look runny, but should still be slightly spongy to the touch.)
Remove from oven and allow to cool completely.

for the mascarpone cream:
adapted from Chef Dennis via Bake and Bait
ingredients:
3 egg yolks
3 tablespoons sugar
1/2 cup plus 2 tablespoons mascarpone
scant cup heavy cream
directions:
Whisk yolks and sugar together very well; place in a small pot over low heat and cook until sugar is completely dissolved.
Remove from heat, pour into a different bowl, and whip until thick and about doubled in size.
Whisk in mascarpone.
In a separate bowl, whip the heavy cream to stiff peaks, then fold it into the zabaglione/mascarpone mixture.
Set in fridge until ready to use (but not for too long; an hour at most before you should use it).

to assemble:
ingredients:
1/4 cup coffee, cold but strong
1 tablespoon liqueur (Marsala, Kahlua, etc.  Go nuts.)
1 teaspoon vanilla extract
cocoa powder, for dusting
1 pint of raspberries, optional
mascarpone cream, recipe above
ladyfingers (about 30 small ones, less if you have larger), either store bought or homemade, recipe above
directions:
Line a 6×3 inch pan with ladyfingers standing upright.
Place a cake board in the bottom, then place as many ladyfingers as can fit along the bottom, using torn pieces to fill in gaps.
Stir the coffee, liqueur, and vanilla together.
Using a pastry brush, lightly brush the coffee mixture over the ladyfingers- they should absorb it, but do not add so much that they are soaked.  
Smooth 1/3 of the cream mixture onto the soaked ladyfingers.
Layer more ladyfingers over the cream mixture, brush with coffee, and layer with cream.
Repeat layering once more.
Dust the top of the tiramisu with cocoa powder, and top with raspberries, if desired.
Refrigerate for at least 1 1/2 hours before unmolding.
Tie a ribbon around the outside for clean presentation.
Enjoy!
