I think the recipe I come out with it closer to the marchigiana version. I didn't have the proper mold, which would be a tall tin cake mold with a bigger diameter at the top (kind of a charlotte mold) so I used a regular cakes spring form 20 cm in diameter with a parchment paper collar. For a 20 cm diameter mold I noticed that the amount of flour I should use it's in the range of the 350 g flour. As a preamble I should also add that as starter I have been using a biga which I have been refreshing daily for the last 20 days, it not like a stiff wild starter but it's working fine. If you don't have a wild starter, or a biga like mine sitting in your kitchen, you could make 12 hours before a "biga" starter mixing about 50 g strong flour and 30 g water and the tip of a knife of yeast, and let it proof covered at room temperature overnight
330 g strong bread flour (the one I used had a 12,9% protein content)
80 g biga refreshed daily (or at least a 12 hour biga)
70 g grated cheese grana or parmigiano and pecorino
65 g of emmental cheese (or better a young pecorino) cubed
2 whole eggs
1 yolk
30 g lard (if you don't have it make a mix of butter and oil)
15 g oil
25 g butter
1/2 teaspoon salt
1/2 teaspoon Saf Gold or other yeast (if you use fresh caked yeast about 10 g)
I kneaded the biga in chunks with 80 g of flour and enough water to make a medium soft dough. Left to double in bulk (it took about 2 and half hours). Meanwhile I beated the eggs and the yolk with the grated cheeses and the salt. Left to rest at room temperature. I soften the butter and lard and mixed with the oil.
Once the dough was doubled in bulk I put it in the stand mixer in chunks with the remaining flour, the egg mixture, the fats and the yeast, I had to add more water, sorry I didn't measure. When it was almost ready I added to the running machine the cheese in cubes.

As I previously said I used a regular spring form, buttered and reinforced with a parchment collar. The dough before rising was a little less the half of the height of the mold.
I covered loosely with wrap and let it proof in a warm place until it reached the rim of the mold. It took 6 hours.

I covered it looosely with foil and baked in a preheated oven at 170 C with vent (I don't have a static option) after 30 minutes I uncovered and let it cook and get a nice golden color about other 15 minutes. I tested the cooking with a long skewers. Let cool on a rack.

It is usually eaten on Easter with salumi or by its own.
