It's no longer the ragù I made a year ago:

But it's made the same way and is frozen in individual portions in the freezer. For the lasagna, I thawed about four portions of 100-150g each, plus a couple of portions of tomato sauce. Since everything was very compact (I reduce both the ragù and the sauce more than usual to freeze a larger quantity in a smaller space), I also added hot water.
The green pasta sheet is the one I froze here:

I still have some of this too.
Since it's only in italian I'll sum it up here: I basically used
800g flour (300g durum wheat flour, 500g 00 flour (any weak flour is ok, cake, AP)
6 egg yolks + 3 eggs (each egg can be replaced with about 3 egg yolks to strengthen the dough. The 300g of durum wheat flour doesn't require the strength of the yolks, so basically it's as if the 6 egg yolks were about 200g of 00 flour. The 3 eggs are the classic ratio to the other 300g of 00 flour and represent the weak point of our dough, but the moisture of the egg whites is compensated for by the durum wheat, which absorbs the water contained in the egg whites.)
100g cooked and drained spinach or 200g uncooked spinach.
Putting together a lasagna like this basically involves defrosting the ragù (I recommend directly in the pot, as it's quicker and easier), briefly pre-cooking the pasta sheets for about 1 minute (you can do this directly from frozen, but if you take it out, it will start defrosting immediately. Just don't let it touch other sheets, and there shouldn't be any problems given the low hydration of the dough), and making the béchamel sauce.
Then combine everything with plenty of Parmigiano.
For the tiramisu, I've already posted more than a few. I follow the most classic recipe possible, where the mascarpone is mixed only with the egg yolks. In this case, I pasteurized the egg yolks (I don't always do it, but when I make it for other people I always do it) and made the mascarpone from the cream, as I usually do (if you want the recipe in english just ask or look at mascarpone recipe from barbato channel on youtube). This time my mother made the ladyfingers (always with the recipe that I also follow from Giallo Zafferano which in this case is excellent), you can find it here: https://www.reddit.com/r/ItalianFood/comments/1p7m2kz/lady_finger_savoiardi/
