"The best way to get your dough to rise better is to make it slightly softer. The easiest way to accomplish this is to increase the amount of water added to the dough. It generally doesn’t take too much added water." Question: We are presently purchasing an
ingredient bag that we add to our flour to make our dough from. We would like to
make this ourselves to save some money. What's the best way to do
it? Answer: Making an ingredient bag, or
"goodie-bag" (as it is better known as) is pretty straightforward.
Some things to remember about your
goodie-bags: Use only instant dry yeast (IDY) in your goodie-bags because it is
designed to be added to the flour without pre-hydration. Technically, you could
also use protected active dry yeast (PADY) in making goodie-bags, but this type
of yeast will be more expensive. Also, it is not as readily available through
our distributors as IDY. If you were to make goodie-bags that had an intended
shelf life of several months, there might be some advantage to using PADY, but
for most of us, we're only looking at a shelf life of a week or two at the most,
and for this, IDY will work just fine.
Question: We make all of our pizzas on
par-baked crusts that we make ourselves during slow time during the day and in
the evenings. Depending upon business, we may keep our par-baked crusts for up
to a week or more in the cooler before we use them. Occasionally, we notice a
little mold growing on one of the crusts in the bag, and we discard the entire
bag of 10 crusts. Is there anything that we can do to prevent the mold growth on
our crusts? Answer: Bread type items will usually begin
to show some indication of mold growth between five and seven days after baking.
Refrigeration may or may not have a significant affect upon retarding the mold
growth as a lot will depend upon the initial level of contamination with mold
spores, moisture content/water activity of the crust, and pH (acidity) of the
crust.
The most effective means of
controlling mold growth is to use a mold inhibitor such as calcium propionate in
the dough formulation. Calcium propionate is available from any bakery
ingredient supplier. It is commonly sold under trade names such as Mycoban or
Guard. No matter what the name, as long as it is food grade calcium propionate,
it will work for you at inhibiting mold growth in your pizza crust.
While some products
might have specific recommendations as to the amount to use, calcium propionate
is usually used in yeast leavened bread type products at levels of between 0.25
and 0.375 percent of the flour weight in your dough formula. This is equal to 2
to 3-ounces per 50-pounds of flour weight. When using calcium propionate, one
must keep in mind that it is most effective when the ph (acidity) of the pizza
crust is at or below 5.5. Remember that a pH of 7 is neutral and anything above
that is basic (alkaline) and anything below 7 is acid. It is a simple matter to
check your pizza crust to determine what the approximate pH is. Purchase a roll
of litmus paper/tape from your local pharmacy. The litmus paper should have a pH
range of 4.5 to 7.5 and a color comparison chart on the side of the container.
Rinse out a blender with distilled
water, then fill it about half full of distilled water and put about 1/4 of a
12-inch diameter crust into the blender and puree it until smooth. Let the
pureed crust-water mix set for a minute or so, and pour off several ounces into
a plastic cup. Dip the litmus paper into the mixture in the cup and compare the
color of the tape to the chart on the side of the tape container. Determine
which color stripe most closely matches with the color of the litmus tape and
read the pH for that color stripe. Ideally, you want your crust to have a pH of
5.7 or lower. A pH of 5.0 to 5.25 is considered ideal. And if it is lower than
this, so much the better. If the pH indicated is higher than 5.7 you will need
to add an acid. The suggested acid is regular, household, white vinegar. This is
added to the dough to lower the pH of the finished (baked) crust. When adding
vinegar, add it in increments of 2 percent based on the total flour weight (one
pound per 50 pounds of flour) in your dough to replace an equal weight of water.
Check the pH of the finished crust and make further changes if
needed.
With the correct finished crust pH
and calcium propionate in your dough formulation you can expect to get at least
7 to 10 days of mold free shelf life on crusts that are stored in the cooler.
