This looks like just what you're looking for.
I have spent years looking for the best tiramisu recipe and have tried dozens to no avail. There have been some good ones, but none of them were amazing, until last night. The combination of Grand Mariner, Espresso, and Dark Rum is a fantastic combination with the mascarpone cheese!
This recipe for Tiramisu is from Sally's Baking Addiction, but is actually a reprint from the book Happiness is Baking Cakes, Pies, Tarts, Muffins, Brownies, Cookies: Desserts from the Queen of Cake by Maida Heatter. Honestly, who cares where it comes from, it is simply the best tiramisu I've ever made. Make some today and be happy!
