Peter,
You wrote earlier in the thread about your experiment with the use of a poolish. I'm interested to know your formula and procedures, and how long did you ferment the poolish itself.
I'm thinking.. what if I cold ferment a poolish for 2 days, instead of cold fermenting the whole dough. Will such poolish transform the light sour, lovely tangy taste of a 2day cold fermented dough, to the dough made with such poolish, then left on room temp to double? If so, it would solve the tight fridge space I'm having...
sallam,
As best I can recall, I made two Papa John's clone dough balls using a preferment.
In one case, I used a natural preferment. The results of that experiment are set forth in Reply 38 at
http://www.pizzamaking.com/forum/index.php/topic,6758.msg60892.html#msg60892. I posted the results because I thought that they were noteworthy. I also wanted to satisfy my curiosity that it was possible to make a naturally leavened PJ clone dough and a pizza using that dough that I wouldn't mind eating.
In the second case, I used a preferment to make another PJ clone dough but instead of using a natural leavening it was leavened with only commercial yeast. I mentioned that experiment in Reply 35 at
http://www.pizzamaking.com/forum/index.php/topic,6749.msg58335.html#msg58335 but I did not post the dough formulation because the crust was too puffy and breadlike and not close enough to a PJ crust to qualify as a PJ clone. However, since you asked me about the latter version, I went back to my PJ clone file and found the dough formulation I actually used. It is as follows:
King Arthur Bread Flour (KABF) (100%): Water (62%): IDY (1.25%): Salt (1.5%): Vegetable (Soybean) Oil (7%): Sugar (4.75%): Total (176.5%):
 344.68 g  12.16 oz  0.76 lbs 213.7 g  7.54 oz  0.47 lbs 4.31 g  0.15 oz  0.01 lbs  1.43 tsp  0.48 tbsp 5.17 g  0.18 oz  0.01 lbs  0.93 tsp  0.31 tbsp 24.13 g  0.85 oz  0.05 lbs  5.31 tsp  1.77 tbsp 16.37 g  0.58 oz  0.04 lbs  4.11 tsp  1.37 tbsp 608.36 g  21.46 oz  1.34 lbs  TF = 0.1394

Note: The KABF is sifted. the dough is for a single 14" pizza; bowl residue compensation = 2.5%
For the preferment, I used 6.08 ounces of the flour (1 c. + 1/3 c. + 1.85 t.), all of the formula water (7.54 ounces, or 3/4 c. + 3 T. + 1.4 t.) and about onehalf of the formula IDY (about 3/4 teaspoon). The preferment was allowed to ferment for about 3 1/2 hours at a room temperature of about 79.5 degrees F. I then combined the preferment with all of the remaining flour, all of the remaining IDY, and the sugar and oil. The dough so formed was allowed to rest at the above room temperature for 1 1/2 hours. I don't recall exactly how I came up with the above prefermentation protocol but usually my guide in matters like this is the two articles by Didier Rosada at

http://web.archive.org/web/20050829015510/www.cafemeetingplace.com/archives/food4_dec2004.htm. What I ended up with was a oneday dough. That was by design.
What you have set forth as a possible approach to use may work but I cannot tell you if your specific numbers will work. For example, you would have to modify the preferment (the amounts of flour, water and IDY) in your case to last for two days at the temperature of your refrigerator, and then combine the preferment with the rest of the formula ingredients to form the final dough and then allow that dough to ferment at room temperature until doubled. The math for doing this sort of thing can get tricky, especially deciding on how to apportion the total formula IDY between the preferment and the final dough, and you might also need to change the amounts of flour and water in the preferment.
