Pizza meets pretzel. (photos by Renee Boeckman) |
So, being that we're in the pizza industry, I contacted the man who I felt could bring pretzels to pizza, Tom "The Dough Doctor" Lehmann. I asked if he'd be willing to humor me a little with a pretzel crust for pizza. To my surprise and delight, he said that he and Jeff Zeak had already been experimenting with pretzel pizza crusts over at the American Institute of Baking. It was only a matter of days before he sent me the following instructions and photos that outline how to make your very own pretzel pizza crust!
If you try this, please let me know and send photos to Liz@PMQ.com. We would love to share them in the magazine. Plus, if you're close enough, I'd like to come over and try the pizza, preferably with a side of cheese sauce for dipping.

How to Make Pretzel Crust Pizza
By Tom "The Dough Doctor" Lehmann
For this experiment, we conducted trials using a
standard pizza crust formula, changing it to a pretzel crust by brushing the
edge of the formed skin with both sodium hydroxide (see warning about sodium
hydroxide below) and sodium bicarbonate (baking soda) solutions immediately before
baking.
We made 2% sodium hydroxide solution and
heated it to 190F/88C before brushing it onto the edge of the dressed pizza
skin. The edge was then lightly sprinkled with kosher salt (this helps it taste
like a pretzel) and the pizza was taken directly to the oven for baking.

We also tried the sodium hydroxide at 6%
solution using cold water and applied the solution cold. This also gave a very
acceptable crust color and flavor. I must caution you that both of these
solutions are highly caustic and extreme care must be exercised in making the
solutions and applying them onto the crust. At the very least, a respiration
mask, eye protection (goggles) and plastic gloves should be worn when making or
handling these solutions.

Our testers found the salted crust to be very
acceptable on all crusts regardless of which solution was used.
Whatever you decide to use for the caustic
solution, be sure to follow all precautionary measures. If you are looking for
the best pretzel flavor, we think that a salt topping works best, but other
toppings can be used. Be sure to use a sanitary, plastic bristle brush to apply
the caustic as it can potentially destroy a natural bristle brush. Lastly, when
forming your dough for the pretzel crust, we achieved the best appearance and
presentation when we formed the dough with raised or beaded edge as opposed to
a flat or non-raised edge.
WARNING: Historically, sodium hydroxide,
commonly known as “lye” is used to make the alkali solution, but there are some
very real risks associated with using a sodium hydroxide solution. It can cause
caustic burns if you get it onto your skin, or it can cause severe eye injury
or even blindness if one were to get it into their eyes. Use extreme caution.
