Use Yeast to Make Your Dough Rise and Shine
By Tracy Morin
Yeast might not get the entire glory given to its pizza making counterparts, like flour and cheese, nevertheless it’s an important a part of the method. Actually, based on Luca Varuni, proprietor and maestro pizzaiolo at Varuni Napoli in Atlanta, it was as soon as thought of downright magical. “People have at all times used yeast—Egyptians used it 5,000 years in the past and, as a result of they have been unaware of the fermentation course of, they thought the chemical response was a miracle,” he recounts. “By 1996, the primary full genome of yeast was mapped.”
Clearly, in in the present day’s world, yeast needn’t stay so mysterious. We tapped some bona fide baking consultants to sort out the entire fundamentals—and loads of the intricacies—behind this key dough ingredient.
Q: What’s the operate of yeast, and what are the differing types obtainable?
Ralf Tschenscher: Yeasts are single-celled microorganisms labeled as members of the fungus household. Within the pizza trade, the commonest yeast species used is Saccharomyces cerevisiae, a key ingredient in pizza baking. It derives its identify from Latinized Greek, that means “sugar fungus,” as a result of it converts sugars and starches into alcohol and carbon dioxide in the course of the fermentation course of. The primary operate of yeast in pizza dough is to permit for leavening; permit the pizza dough to mature and enhance the gluten construction; and improve the flavour and aroma of the pizza crust.
Paul Brilliant: There are two various kinds of bakers yeast: recent (or moist) and dry. Contemporary yeast is comprised of compressed or block yeast, offered in 1- to 5-lb. blocks. Dry yeast is obtainable in energetic dry and on the spot varieties.
“As recent, energetic dry and on the spot yeasts are types of the identical species, they are going to all produce comparable fermentation taste, gassing exercise and end-baked pizza texture when used appropriately.”

Q: How ought to a pizza maker select the correct kind of yeast for his operation?
PB: Choosing the proper yeast depends upon the pizzeria’s course of and the dough maker’s choice or consolation stage with utilizing a specific yeast kind. As recent, energetic dry and on the spot yeasts are types of the identical species, they are going to all produce comparable fermentation taste, gassing exercise and end-baked pizza texture when used appropriately. Here’s a fast breakdown:
Contemporary yeast can be utilized at any water or dough temperature and is the best to make use of of all yeast sorts. A unfavorable of recent yeast is that it has the shortest shelf life and customarily must be used inside weeks of buy.
Energetic dry yeast (ADY) have to be rehydrated for 5 minutes utilizing a small portion of heat water (100° to 110°F) earlier than including to the flour. As soon as hydrated, the remainder of the dough water could be at any temperature to attain the specified completed dough temperature. If ADY is just not rehydrated previous to including to the blending bowl, the yeast particles won’t dissolve into the dough after mixing, leading to a slow-proofing yeast. Unopened ADY has a two-year shelf life. As soon as opened, it must be transferred to an hermetic container and saved below refrigeration for as much as two months.
Immediate dry yeast (or IDY) is designed to be added on to dry elements and blended previous to the addition of water. Prehydration of IDY will lead to a lack of gassing exercise and slower-proofing doughs. Chilly or ice-water temperatures shouldn’t be used for this sort of yeast, as most yeast-activity water temperatures are 80°F or greater. IDY has comparable shelf-life traits as ADY.
RT: To reply this, ask your self: What are your targets—are you operating a single-unit pizzeria or chain, working in a wholesale operation, concerned in frozen dough manufacturing? What’s going to your weekly utilization be? Can you order yeast each week? That is virtually important in case you are utilizing recent yeast.
From my expertise, in North America, nearly all of pizzaioli are utilizing both IDY or ADY. One motive is utilization stage—in contrast with recent or compressed yeast, IDY utilization is 2/3 much less, and ADY utilization is half. Another excuse is that IDY and ADY present a for much longer shelf life than recent yeast.
“Deactivated yeast…reduces the blending time and creates extra extensible dough, which permits pizzaioli in coaching to stretch the pizza dough rather more simply with out tearing the pie.”
— Ralf Tschenscher, LeSaffre Yeast Company
Luca Varuni: The kind of yeast and the quantity you select depends upon what kind of fermentation, timing and digestibility you wish to give to your dough. At Varuni Napoli, we use what we name in Naples “lievito madre,” or “mom yeast,” which is a sourdough yeast. The mom yeast is basically an acidic dough obtained by mixing flour and water. Fermentation could be triggered by leaving the flour and water uncovered to the air and an entire collection of exogenous micro organism and yeasts. Our mom yeast was initially made 9 years in the past, after I opened my first Varuni Napoli location. We additionally use a really small quantity of recent yeast together with our mom yeast to assist the fermentation and the rising of the dough.
For newcomers, I’d counsel ADY or IDY, however recent yeast produces pizza dough with just a little extra taste in comparison with dry yeast. In case you are prepared to take the problem, you may give it a attempt with sourdough yeast, which can give taste to your dough and produce a crust that’s barely crispier on the skin, whereas the within stays mild and ethereal for an incredible texture expertise.

Q: What are some issues to remember when working with completely different yeast sorts?
PB: When making formulation modifications from one yeast kind to a different, use the next conversion charges to attain comparable gassing actions: 1 lb. of recent = 0.5 lb. of ADY = 0.4 lb. IDY. When altering from recent to dry yeast, improve water to make up for the water loss from recent yeast. For instance, in case your formulation requires 2 lb. of recent yeast and the pizzeria is altering to IDY, the conversion shall be 0.8 lb. of IDY + 1.2 lb. of further dough water.
Contemporary yeast ought to at all times be saved at temperatures under 45°F. Additionally, recent yeast ought to by no means sit unrefrigerated within the pizza store for greater than half-hour, as its warming could have a unfavorable influence in yeast gassing exercise, leading to sluggish proofing instances.
RT: When you resolve to provide frozen doughs and your goal is to attain a really lengthy freezer shelf life, we propose utilizing recent yeast—it offers the most effective leads to frozen pizza dough manufacturing. Additionally, there’s one other kind of yeast, deactivated yeast or inactive yeast, which has gained vital recognition. What’s distinctive about deactivated yeast is that it reduces the blending time and creates extra extensible dough, which permits pizzaioli in coaching to stretch the pizza dough rather more simply with out tearing the pie. Notice: The addition of typical yeast remains to be required.
LV: The mixer mustn’t influence what yeast you resolve to make use of. At Varuni Napoli, we use solely spiral mixers, that are gentler on the dough and stop dough from overheating. However, relying on the kind of yeast you employ, you’ll want to watch out of the way in which you add it to the mixer. For instance, yeast doesn’t love salt, and salt in direct contact with yeast will kill it. It will scale back the power of the yeast to correctly ferment the dough. Be centered when including the yeast and the remaining elements to the mixer. When you add water, salt and yeast, then depart to have a glass of wine and are available again later so as to add flour, your dough won’t rise correctly!
