Lemon Curd Tiramisu And Specullos Russian Cigarettes Cookies

Pour the 80 grams of sugar, 2 eggs, 3 egg yolks, and the juice of 2 lemons into a saucepan. Mix and bring to a boil over low heat, stirring constantly until thickened. Upon first boil, add the butter all at once and mix quickly. Set aside.
If you end up with any pieces of cooked egg whites you can pass your curd through a sieve to make it smooth. Allow your lemon curd to cool before putting it in a pastry bag.
Split the whites from the yolks for the remaining 3 eggs into two bowls.
Beat the yolks with 100 grams of granulated sugar until the mixture whitens. Add the mascarpone and mix.
Whisk the egg whites until firm peaks form and fold gently with a spatula into the mascarpone/ egg/sugar mixture.
Put a layer of mascarpone cream in a clear bowl.
Using the pastry bag, drop a thin layer of lemon curd (it is important to wait until the curd is cold to use it, otherwise, it would melt the cream).
Cover with a layer of Russian cigarettes from which you had cut the ends with a saw-edgeg knife (for a more even finish).
Repeat all 3 layers for a second time and finish with the mascarpone cream.
As pictured in the photo, you can put small amounts of lemon curd to decorate your tiramisu. Cover your dish with a plastic film and refrigerate for a minimum of 4 hours.
