Very Large Bubbles in Pizza Dough

Bingo. phatch nailed it, no question./img/vbsmilies/smilies/thumb.gif

 

Unless the OP is describing the common occurance of bubblling in the oven, in which case you would use a pizza poke to pop them while the pizza cooks.
The pizzaoli shouldn't have any problem with this, it should be part of tending the pizzas, just as rotating or spinning them would be, as most ovens have hot spots.

 

what flour are you using ... self raising flour?

 

It might be that every once in a while the yeast is replaced or grows with lactic bacterias.
Bubbles are carbon dioxide created by yeast fermentating the sugar released by starch. The large ones are sometimes created by lactic bacteria who have the possibility to get more sugar from starch.
This is hard to control. check ingredients that you use with flour. Do you add milk? do you add sugar as starter?
Sometimes this happes because something reduce the activity of yeast, example (but will not be your case) is the use of honey as starter.  Other example is the use of salt or if the dough is heated too much, depressing the yeast population and having lactic acid overcome.

 

 hi
I am the op's sous, and i thought i would chime in,
we do use honey in our recipe, not sugar.
our flour is all purpose. we tried cutting it with pastry flour, but found it way too cakie.
docking is not really an option, for both time and quality reasons.
our production system is both time and temperature consistent yet as the week progresses we seem to have more problems (Tuesday is great, Friday is awful)
tuscan chef, can you elaborate more on the lactic bacteria's effects on the dough?

 

our restaurant has been around for 15 years now and they never docked before, 
we got a new oven last year and started to experience inconsistencies.
we modified to dough recipe and production to eliminate as many problems as possible and yet leading up to the weekend there seem to be more large bubbles.
we are trying to find the possible source of the problem, and not just a quick solution.

 

I too can't understand why docking would cause a quality issue but I did want to ask........as far as time.........a docking pin takes less than 2 seconds to run across the pie before you sauce so............

You mentioned Tuesday was fine but Friday wasn't? How often are you making dough and are you combining batches? I.e. adding what's left over fro Tuesday to Fridays batch. Does a different person make the dough Tuesday as opposed to Friday?

Are you using a cold method for dough production? That's adding the yeast directly to the flour and then combining the dough with 50% ice water/tap water instead of blooming the yeast in warn water prior.

Is it cake yeast or dry/active?

At any rate.........

I also believe that tending to the pizza's is a necessary thing. Sometimes....no matter what you do.........a bubble will appear.  JMHPO

 

 what i meant by quality issue is that we are trying to figure out the source of the problem,
with docking being the last possible solution, as it solves a problem at the end of a long process (making the dough, proofing, rolling...)
we are trying to solve the problem earlier in the process. it might have to come to docking, only if nothing else works.
as far as our process goes. we use dry instant yeast, we dont combine batches, we have our formula, and its translated into 3 different size batches and me make the dough every night after service according to what we expect tomorrow  to look like.
we control temp by averaging to 76 (water, flour, room, friction) ala cavel, first autolysing then adding the yeast oil, honey and salt.
then the dough get batch proof in the walkin over night and portioned/balled in the morning.
only my chef and i make the dough, and we use a white board to track temp. and batch sizes

 

seriously? I would have thought that the dough would have to be docked every time, cause you were making right., not wrong.  you have said that it didn't used to do this, i would be worried if it didn't. Its the sign of a healthy dough.   

 

I'm not a professional chef, but I make a ton of pizza, and used to service appliances, so I hope nobody jumps on me for posting here. /img/vbsmilies/smilies/smile.gif

I've never seen a really good pizza that didn't have a few bubbles, and popping them is a normal part of baking.

On the other hand, you mentioned that you started having problems when you got your new oven.  Some ovens have a very wide temerature spread between where the heater comes on and then turns off (this is actually a thermostat defect). Others have an insufficient recovery rate, which is caused by having too small a heater, or a damaged heater or running the wrong heater for the electrical service in your building (for example a 240 volt heater on a 208 or 120 volt circuit) or burned/damaged wiring inside the oven.

This means that opening and closing the door too often or loading the oven up with pizza will cool the oven down enough that you're not cooking anywhere near where you think you are. You might want to see if you can borrow a good high temp thermometer see what's actually going on in there while it's in use. I'm guessing you'll find it's nowhere near as hot as it's supposed to be.

Good luck!

And for no special reason except that you guys talking about bubbly pizza has made me hungry, here's one of mine

 

I agree with Web Monkey as the quotes from your above post says it all . You didn't have these problems before on such a scale until the arrival of the new oven and during busy periods, you see the problem increase- because you are opening the oven more presumably- thus lowering the temperature even more. 


As Web Monkey suggests you could get a thermometer to see if this is the problem. Then you can get if fixed or  you could just 'get to know ' your oven by adjusting the temperatures and keeping an eye on the results.

 

after rereading, I agree too. AND THAT PIZZA LOOKS YUMMY!!

 

  I knew that someday, all those years of driving around in a service truck would pay off!

Thanks!  It's a real complement coming from a pro!

Luckily, it takes a couple of days to make the dough and prep everything. If I could do it in a couple of hours, I'd look like Jabba The Hut.

I am also glad that good dough takes at least 12 hours to cold proof.  I would need a crane to leave the house otherwise.

 

I made pizza for years.  One of our main bubble problems was from dough handling.  Does your dough cut into portions and rolled into doughballs?  A doughball made of 3 or 4 cut pieces will have more bubbles in it than one made from 1 or 2 cut pieces.  When the doughball was rolled by hand (before proofing), the air bubbles can be worked out and popped by more experienced hands.  After proofing, when the dough is formed into a crust, visible bubbles can be popped.  Do different people make doughballs on Tuesdays and Fridays?
