Recently, new member Beckamojo over on the Mellow Bakers enquired about getting a white sandwich bread recipe to use in her 13 in x 5 in x 5 in Pullman pan. She was having a few issues with her trials at making a Pain de Mie from a US (cups-based) recipe including not knowing how much dough she needed for her large Pullman. Jacqueline, another Mellow Baker, asked if Becka had digital scales so she could be more precise than her original use of cups for measuring. We would also need to look at proofing times and make sure her process didn’t end up with over-proofed dough.
I did a little hunting and this is what I suggested:
Check the King Arthur recipe for a Pain de Mie which is suitable for a 13 x 4 x 4 pan. It is a bit smaller than your 13 x 5 x 5 pan so you’ll want to increase the amounts which are, fortunately, given in weights as well as volume. With luck, they will someday upgrade to include grams, in spite of the general American public’s dogged resistance to embracing the so-much-simpler metric system.
Let’s have a peek and break it down here so you can see what is going on.
Their original recipe reads:
2/3 cup (5 3/8 ounces) milk
1 cup (8 ounces) water
6 tablespoons (3 ounces) butter
2 1/4 teaspoons salt
3 tablespoons (1 1/4 ounces) sugar
1/4 cup (1 1/8 ounces) Baker’s Special Dry Milk or nonfat dry milk
3 tablespoons (1 1/4 ounces) potato flour
4 3/4 cups (20 ounces) King Arthur Unbleached All-Purpose Flour
2 teaspoons instant yeast
So first we need to convert the above to something simpler: grams. Let’s start with the milk:
5 3/8 oz. Ugh, fractions in odd numbers.
We begin by finding out what that ounce fraction is in percentages, so we take the 3 and divide it by 8:
3 ÷ 8 = 0.375.
Let’s round it up and go with .4 then.
Now the milk is 5.4 ounces instead of 5 3/8. But we want grams. The formula to convert ounces to grams is:
Ounces x 28.35 = grams
(You may want to make note of that, it’s hugely handy; I wrote it on a bit of tape and stuck it on my kitchen calculator until I remembered it by heart)
5.4 x 28.35 = 153 grams.
Now we know the recipe needs 153 grams of milk. Next! 8 oz water:
8 x 28.35 = 227g water
Let’s zoom through the rest:
3 x 28.35 = 85g butter
Teaspoons… let’s leave those for a bit.
1.25 x 28.35 = 35 g sugar
1.125 x 28.35 = 32 g dry milk
1.25 x 28.35 = 35 g potato flour
20 x 28.35 = 567 g AP flour
Teaspoons… some of this needs research. The staples you may want to keep note of: teaspoon and tablespoon weights of salt, yeast, sugar, vanilla. If it helps:
I happen to know that a teaspoon of salt is ~6 g so 6 x 2.25 = 14g salt
Instant Dry Yeast is 3.1g per teaspoon so 2 teaspoons is 6g.
A “packet” of yeast contains anywhere from 6 to 17 grams, depending on location and manufacturer: they’re all over the darned map. Instead, go by the general rule that you use 1% of the FLOUR WEIGHT in Instant Dry Yeast and you should be good. Here, the flour weight is 567g, so 6g is ~1%. If you were to use ACTIVE Dry Yeast, you’d want to use 1.5% instead. Instant Dry is better.
dry milk: 32g
potato flour: 35g
All-Purpose Flour: 567g
Instant yeast: 6g
Total weight: 1154 grams
Since this amount is for a 13 x 4 x 4 pan, we need an extra inch to fill your 13 x 5 x 5 or increase the amount by 56.25%.
Therefore we need to get each of the above weights up to 156.25%:
milk: 153 x 1.5625 = 239 (I have a % button on my calculator so that makes it easier: 153 + 56.25%:
dry milk: 50g
potato flour: 55g
All-Purpose Flour: 886g
Instant yeast: 9g
NEW total weight: 1803 grams
NOTE: I had originally miscalculated the new percentage as 125% which accounted for a pan size of 4 x 4 increased to 4 X 5. However, sharp reader Erica (see comments bellow) caught the mistake. We need to calculate an increase from a 4 x 4 pan to 5 x 5 which is 56.25% more.
Now, you can follow the directions given on the King Arthur page and have the right quantity of dough for your Pullman pan based on their recipe. Use either the hand or mixer method (if you have one) the bread machine is probably not big enough to take all that dough.
• After your bulk proofing (the first one), divide the dough evenly into 5 pieces (1803 ÷ 5 = 360g each). Roll each into a ball and let them rest for at least 15 minutes under cling film.
• Flatten each piece into a rectangle. Roll up into a log about 5″ wide.
• Oil or spray the walls and the lid. Place the 5 dough logs evenly in the pan. Let it rise again until the dough is 90% from the top of the pan, about 30-40 minutes (depending on how warm your kitchen is).
• Bake as per instructions
This not only gives a pretty loaf, you can then split the loaf in sections and freeze what you won’t use for a while. This is handy for a very large pan like yours.
• we found a white bread Pullman recipe, with weights!
• we’ve learned how to convert it to grams and
• scaled it up to 156% to suit your larger pan.
All that’s left now is for you to give it a go and see if you like the resulting bread! If you do and the size is good, you now know you need a recipe that will give about 1450 grams of dough. Found a Challah bread recipe that gives you a 750g loaf? You can make that suit your pans easily.
Now we will wait and see what Beckamojo makes of this information. My hope is that she, and other visitors to the site, can feel comfortable looking at a recipe and giving a whirl at modifying it to their needs. Hey, if I can do the math, most anyone can. And I’ll admit readily that math was my very worst subject in school.
