Panettone breaking apart
Hello, I've tried this panettone recipe a couple of times
Ingredients (first dough )
115g pasta madre
400g panettone flour
200g water
125g sugar
90g yolk
120g unsalted butter
-----------Fermentation until it triples in size which takes about 16h at 20 C---------------------------------------------
Ingredients (second dough )
All of the first dough
100g panettone flour (super high protein flour)
110g sugar
50g honey
160g yolk
6.5g salt
215g unsalted butter
350g dried fruits
----------------Fermentation in mold which takes about 12 h at 20 C-----------------------------------------------------
Baking at 180 C for about 50 min
The problem is that when I hang it upside down the panettone breaks apart, I don't know what the problem could be, I've tried decreasing the amount of dried fruits but it still breaks when hung upside down.
My theory is that I should add more gluten to the flour, decrease the fermentation time and let it be in the oven a bit more.
I'm a beginner at this so sorry if I didn't give enough data, will provide more if needed. Thank you for your time!
