I really love your 30 for 3 fic series (most of all the Yule fics) and the KH/Furuba crossover. XDD And also A Shoggoth on the Chimney, which is just plain awesome. XD
And for a recipe... how about pavé? Bear with me, though, 'cuz I'm translating the ingredients from portuguese XD;; and I'm really not all that familiar with english cooking terms.
The covering cream thingie 1 can of milk cream, without the watery part 3 egg whites 6 soup spoons sugar
The filling cream thingie 3 egg yolks 1 can condensed milk 1 same can of normal milk (use the previous can for measuring) half a soup spoon of corn... corn flour thingie... oh, jesus, I've no idea what it's called in english. I'm pretty sure normal flour also works. It's mainly for consistence, it doesn't add much flavor, and some recipes skip it alltogether
Decorate with Half a tablet of bitter chocolate bar shaved or cut in little pieces Bakery sugar for sprinkling
Take the flour, the yolk, the condensed milk and normal milk to low cooking and stir until it's thick and consistent (the thickness is a matter of personal taste). Then let it cool down. Meanwhile whip the egg whites, then add the sugar and whip it further. Add the milk cream little by little, stirring carefully, and set it aside.
Mix the vermouth with a teacup of water and heat it until it boils. Lightly humidify half the cookies in this mix (don't overdo it or they'll turn into a sloshy paste) and use them to cover the bottom of a round or rectangular recipient. Spread the yolk cream over the cookies, add another layer of humidified cookies and then the covering. If you have more cookies and more filling you can add more layers. Decorate with the chocolate and sugar at will and put on the fridge for about 4 hours.
If you don't want to use vermouth or liquor, or plan on serving it to minors, you can use warm milk with sugar and cinnamon to humidify the cookies. :D
