Thanks Peter, that's an interesting formula. Seems like a lot of yeast and a low TF? Or perhaps all that yeast makes the low TF work? I'll try it if Norma or .I can find the flour
Steve,
The amount of yeast, whether in the form of cake yeast or IDY, really isn't all that much, especially for a short, room-temperature fermented dough. To come up with an IDY version of the dough formulation I posted for a 15" pizza, I calculated the amount of water in 3.45 grams of cake yeast and added that amount of water to the original formula water, while keeping all of the rest of the ingredients the same (by percents) as originally given. I then converted the 3.45 grams of cake yeast to an IDY value, using the theartisan.net yeast conversion table that Paul referenced. This is what I ended up with:
General Mills Gold Medal Full Strength Flour #53381 (100%): Water (50.8561%): IDY (0.4056%): Salt (1.77188%): Olive Oil (0.4%): Vegetable (Soybean) Oil (3.6%): Sugar (2.10938%): Total (159.14296%):
| 276.12 g | 9.74 oz | 0.61 lbs 140.42 g | 4.95 oz | 0.31 lbs 1.12 g | 0.04 oz | 0 lbs | 0.37 tsp | 0.12 tbsp 4.89 g | 0.17 oz | 0.01 lbs | 0.88 tsp | 0.29 tbsp 1.1 g | 0.04 oz | 0 lbs | 0.25 tsp | 0.08 tbsp 9.94 g | 0.35 oz | 0.02 lbs | 2.19 tsp | 0.73 tbsp 5.82 g | 0.21 oz | 0.01 lbs | 1.46 tsp | 0.49 tbsp 439.42 g | 15.5 oz | 0.97 lbs | TF = 0.087712

Note: Dough is for a single 15" pizza; the vegetable (soybean) oil and olive oil blend have a combined baker's percent of 4%, with 90% being vegetable (soybean) oil and 10% being olive oil; thickness factor = 0.087712; no bowl residue compensation
As you can see from the above, the amount of IDY is only 0.4056%. That might be suitable for a cold fermented dough, but for a short-term room temperature fermented dough, I would usually be thinking of about 0.70-0.80%. At 0.4056% IDY, I think that you would need to give the dough a temperature assist. The PMQTT member who posted the original recipe said that he would put pans of dough on the oven for a short period in order to get them to rise faster. But even apart from that measure, it is likely that the pans that are stacked to rise are in a pretty warm environment, possibly in the proximity of the oven. With your instincts, I am sure that you will figure out how to make the dough work. BTW, while I was looking for something over at the PMQTT to add to this reply, I stumbled across another post by the PMQTT member who posted the original recipe. That post adds more detail on the preparation and management of the dough. The post/thread is at

You are correct about the thickness factor. It is lower than what we have mostly seen elsewhere and have used before. However, as I noted in Reply 3 at
http://www.pizzamaking.com/forum/index.php/topic,10534.msg93333.html#msg93333, I have had Greek style pizzas with a lower thickness factor value. The thickness factor mentioned in that post was 0.0891, or just a bit more than the thickness factor value of 0.087712 for the dough formulation given above in this post. However, interestingly, for a 10" pizza, the amount of dough used by the PMQTT poster is 7 ounces. That converts to a thickness factor of 0.08913, which is about the same as mentioned in Reply 3 referenced above. It looks like it is a small world. BTW, the PMQTT poster is in Worcester, MA, where there are apparently a lot of Greek style pizza places.
I know you know this, but for the benefit of others who might want to try the IDY version of the above dough, the expanded dough calculating tool at
http://www.pizzamaking.com/expanded_calculator.html can be used to make any size and numbers of pizzas. The thickness factor values mentioned above are so close to each other that it perhaps doesn't matter which value is used. Of course, if one wants to use a larger thickness factor value, that should work also.
