Well, since my Virgin America Flight has free wifi and an electric outlet for our netbook, i figured I might as well be productive :)
The recipe for the christmas trees was a modificiation from this recipe on Bread & Honey.
The only difference is that I used whipping cream instead of milk, and I used ground cloves instead of nutmeg.
For the white chocolate ganache simply bring 2 cups of heavy whipping cream to a simmer. As soon as it begins to bubble around the edge of the pot, pour it over 8-11 oz of white chocolate. Let it sit for a minute or so, then whisk together untilu all the chocolate has melted. Refrigerate until the sauce thickens and it ready to pipe onto the cookies.
