I have very few loves when it comes to sweet dishes and a good tiramisu is one of them. Combining some of my favourites, and surprisingly some of my least favourite ingredients, this Italian dessert make for a wonderfully light finish to a dinner or an indulgent treat at any other time of the day.
According to wikipedia tiramisu is not all that old as a recipe, apparently only coming into popularity in the 1960's, however there is a fair amount of contention on its origins with claims going back to the 1700's. But honestly, who cares :-)
Tiramisu is a layered dessert of biscuit/sponge and a rich yet light mascarpone mix with Italian liqueur and espresso coffee. The literal translation is 'pick me up' or, and I like this variation, 'cheer me up', as does for me. The recipe is relatively simple but some patience is required.
As always there are variations, some recipes use only egg whites to mix in with the mascarpone, others suggest using whipped cream, unsurprisingly I found a mix of both works well, as per the below recipe.
The part of the recipe that does give me pause is the use of raw eggs. I am no fan of the flavour of eggs usually and eating raw eggs in any form gives me culinary nightmares. However my love of tiramisu was formed well before I knew how it was actually made.
The key here is to 'pasteurise' the eggs, at a minimum, the egg yolk prior or during the preparation. It is simply heating the yolk to approximately ~60℃ (~140℉) for at least 7 mins to kill off most of the bacteria. If you have a sous vide this would be the most reliable option to pasteurise your eggs prior to separating your yolks and whites as the temperature can be controlled, heat the water to 60℃ and let the eggs sit up to and hour. The eggs will retain a 'raw' consistency at this temperature, to actually 'cook' the eggs would require a higher temp. If you don't have a sous vide, then heat the egg yolks to that temperature, at a minimum, as per the recipe below provides.
