When it comes to home pizza making, I am still very much a novice struggling to find the path to great dough. So far, my seven month journey has all been in the years B.Y. or Before Yeast. This is about to change, and hopefully in a big way.
Most of us home pizza makers face limitations due to the highest temperature attainable by most standard kitchen ranges, which is almost always 550°F. You can make very good pizza at this temperature, but never a great one. The crust will not have quite the same wonderfully airy texture made possible by a high temperature (800°F plus) oven or the char which many of us find pleasing. There is of course a way around this which involves your oven’s self cleaning cycle and potentially a Dremel or pair of bolt cutters, but you didn’t hear it from me and Mrs. Blogger put the kabash on such a workaround happening in the Blogger household!
I may not have a hot enough oven to get a quick rise and a good char, but I can strive to increase the flavor of any crust I make. Enter my Italian wild yeast cultures obtained from Sourdoughs International. It’s time to enter the realm of the tang, the realm of deliciously flavorful crust which is another notch up from crusts made with the ubiquitous Bakers Yeast. Saccharomyces cerevisiaewill hold me back no longer! I am ready to step into the light, into the first year of our lord After Yeast.
(Note: to be fair, an incredible crust can be made from dough using everyday instant yeast. Flavor is primarily derived through the skillful manipulation of the fermentation process, regardless of the quality of dough or type of yeast used. An adequately fermented dough made from cheap, all purpose flour using instant yeast WILL taste better, potentially much better, than a dough made with the highest quality Italian 00 flour which has not been adequately fermented. Flour quality being the most important factor in the quality of the finished pizza crust is a myth. All things being equal, I just happen to personally prefer the unique flavors of a sourdough)
Armed with my copy of Ed Wood’s Classic Sourdoughs, my first step was constructing a proofing box. It is important to have the wild yeast starter activated from its dormant state while at a warm temperature (around 85°F). The lactic acid bacterias (lactobacilli), which give breads made with a wild yeast starter such a wide depth of flavors, prefer an acidic environment. A warm temperature helps promote an acidic atmosphere, which the lactobacilli want and which most airborne yeasts looking to add their own flavor to the mix do not like.
Home Depot provided the parts to construct my first proofing box, which is essentially a light bulb put inside of a Styrofoam cooler, along with a quart canning jar containing the wild yeast starter and additional flour and water neeeded to activate it. The parts list for the proofing box was simple and relatively inexpensive:
- Westinghouse 8ft lamp cord set (cable SPT-1) $5.98
- GE Crystal Clear 25 watt auradescent decorative bulb, Type F, 2 Pack $2.67
- Leviton porcelain light socket/lampholder with pullchain $3.39
- 4 11/16 square junction box 3/4″ x 1″ $4.75
- AcuRite indoor/outdoor thermometer & hygrometer $2.98
- One Styrofoam cooler $4.98
- Total $24.75

Proofing Box Supplies. A copy of the Una Pizza Napoletana menu for good luck.
After a quick ten minutes unwrapping everything, wiring the cord into the light socket and covering everything in electrical tape, I had my light socket in the junction box and the proofing box ready to go. The light socket and bulb, quart jar for the yeast and thermometer fit under the Styrofoam cooler, which rests upside down over these items.

Completed Yeast Proofing Box
The next step was to activate the dormant wild yeast culture by feeding it a mixture of flour and water. The culture was captured by Marco Parente on Camaldoli Hill in Naples, Italy and the starter is referred to as the Camaldoli Culture. Marco Parente is a recognized pizza expert on authentic pizza Napoletana and consultant to pizzerias around the world. Marco can be found giving informed advice on Pizzamaking.com, which is the internet’s definitive resource for home pizza making. Marco, known as pizzanapoletana on the forum, along with people in the pizza business and home pizza making experts like the invaluable Pete-zza, can help you craft any type of pizza you want at home. These people are the true experts, and a few people involved with this site have gone on to launch their own pizzerias.

Molino Caputo Italian Type 00 Flour, Calmaldoli Starter and Ed Wood's "Classic Sourdoughs". A lit candle of the Madonna bestows a blessing on the viability of the yeast culture.
After mixing in the dormant wild yeast culture with 3/4 cup of Molino Caputo Italian Type 00 pizza flour and 1 cup of warm distilled water, I gave the mixture a vigorous stir to incorporate some air and loosely sealed the top on the canning jar. With care and regular feedings, this yeast culture could last for my entire lifetime.
Hopefully a tangy, true sourdough crust is in its infancy in the Blogger household, ready to usher forth a new era of better pizza and shed light on my previous trollings in the dark ages Before Yeast.
I’ll update this post with results and pictures of the first pizzas made with this new Italian sourdough culture. Take care!


I made your proof box today. i have had the same sourdough starter as you for months now, but have been searching for a proof box to purchase, but came across your ‘recipe’ for making one. So easy! i took my list to Home Depot and found everything needed.
i am waiting for the flour to arrive (antimo caputo) before i start the proofing. this is a new hobby (passion) for me since retiring several months ago. it is like a big science experiement that i get to eat ……
thanks again
p.s. i tried making limoncello last year but it was terrible….i am following your recipes to see what turned out best.
Kimmiko, let us all know how your sourdough experiments and limoncello making come along. Awesome!
IMPORTANT: Keep an eye on your proofing box……it can get quite hot in there. Once the temp gets up to 85° to 90°F, turn the light off. The cooler should keep the temp close to 85 degrees for a few hours.
Be prepared for some frustration. I killed one jar of my sourdough culture, but that’s what a backup is for
Good luck.
pizzablogger- what if a smaller wattage bulb were used instead of 25w? would that raise the temp enough to activate but prevent killing the bacteria?
Julia, a smaller bulb could work as well. I think it really depends on the size of the styrofoam cooler you are using. My initial cooler and lightbulb set-up, as shown in my post, got a mason jar of starter slurry up to 85°F in about 30 minutes or so. I am now using a small infrared thermometer that is made to be put against a glass and measure the temp of the liquid inside of it.
Even with a now bigger cooler, I still have to monitor it from time to time or it gets too hot. So, a smaller bulb would most likely allow you to not have to monitor as much and lessens the chance you would kill your culture…….however, a smaller bulb may take a long time to bring a culture up to 85°F. The very fist time you activate a dried culture, you want to get it up to 85°F ASAP. A bigger bulb may be better for initial activation and the smaller for preparation of an already activated (dormant in refrigerator) culture.
pizzablogger- many thanks for the rapid reply. your suggestions make sense.
am planning to build the proof box-per your easy list –but will get two wattages of bulbs…
pizza blogger- we set up our proof box and also put a dimmer switch on it. could not find the 25 w auradescent bulb so we used a 40w one and with the dimmer have been able to keep it right at 85 to 87 deg.
within first 24 hrs nice bubbles- last night we fed it for the first time and prior to feeding it had about 0.5 inch of hooch on the top. this morning it shows about the same level of ingredients in the jar with the hooch again separated on the top.
is this normal to have the hooch separate so quickly to the top without much bubbling? or have we contamination of some sort? although according to ed’s book, the hooch will be at the bottom or in the middle if it is contaminated.
thank you.
