Pane Soffiato: Getting hollow Rosetta and Tartaruga rolls

Toast

Success at last. A new technique for forming the rolls by flattening the dough in a pasta machine and then rolling them up under tension like a spring has at last given me the hollow interiors that I have been trying to get for the past 4 years.

Sweet! Looks brilliant. Well done.

Can't see the recipe on the link provided. Just pictures.

EDIT: Ok I see instructions with each picture opened up. Any chance you can post the formula here. I know these breads use a biga with most of the total flour.

Ingredients are on the first picture but I will repeat them here. In any case, it's the classic rosetta recipe, indirect method, 16-20hr biga, 52% final hydration. I use Gold Medal bread flour with good results.

Ingredients:
Biga: 
800g of bread flour ( I use Gold Medal)
350g of water @75 degrees F.
1 tsp instant yeast

Final Mix: 
All the biga (18hr fermentation)
80g bread flour
1 tbsp Diastatic Malt Powder
108g refrigerated H2O
1 tbsp fine salt

and what do you stuff in them?  I can think of all kinds of fillings!  

-not to mention a cheese liner-

That is so cool!

. . . that there isn't some kind of sorcery going on here :-)

I've never seen anything like that before. Thanks for sharing! I'm curious to try it myself.

The two critical components in terms of technique are getting a tight roll that is under tension and lots of steam in the first 5 minutes of baking.

Don't skimp on the biga fermentation either. It's important to have a dough which is both elastic and extensible.

Those are awesome. Well done!

What is the rolling technique after they are flattened? Rolling like a hotdog? Or like rolling into a ball? And then is there a proof time or do they go right into a hot, steamy oven?

This is something I want to try to replicate.

French fry cutter and isn't that an apple slicer/corer?    We are going to play in the kitchen now!  

Wowwee! didn't have to go into zero gravity to do it!   

Took me a while to find the directions but ... ever try cutting using the pill box?

Based on the previous questions, I have made some notes on the batch I made today and also updated the recipe.

1. I fold the doughball 6 times when rolling it out. Four times on the long side and two times on the short side to make a long narrow ribbon.

2. I stretch the ribbon out about 24-28 inches before I roll it up. It should be about 3cm wide after it is stretched.
