The Baker's Percentage

Hi all, I just thought I'd share with you one of the single most useful baking related tidbits I've ever come across - the baker's percentage

I've been making breads and pizzas using this easy calculation for months now and not once have I ever ended up making something that didn't work out brilliantly. Using this you will give yourself an almost 100% guarantee of success when it comes to anything bread based, be it high hydration sourdough or a pizza base. So here's an example of how it works, you will need a kitchen scale to use it to the best effect -

Strong bread flour - 600g - 100%
Consider your bread flour to be 100% and base all other percentages on this
Water - 420ml - 70%
Easily worked out - 1% of 600 is 6, multiply by 70 and there you have it
Yeast - 6g - 1%
1% dried yeast for most breads is usually fine, any more and you risk over-proofing
Salt - 12g - 2%
You'll want 1-2% salt in breads, I tend to use 1% if I'm making pizza dough, but 2% for most other loaves

And it's that easy, that recipe will give you a 1.2kg ball of dough at 70% hydration. The proofing and baking process will vary from person to person so I won't go into that, but this calculation's a foolproof way of making dough.

As far as the hydration goes - for the vast majority of purposes, a 60% to 70% hydration is your best bet. A drier dough (55% to 60%) will be easier to work with, but you won't get as much rise in the oven and will end up with a more dense bread. A higher hydration - 67.5% to 75% will be much harder to work with and will start off as a sticky mass that takes quite a lot of kneading to get to a workable dough, but you'll be rewarded with a much higher rising, lighter loaf

Obviously you can add other ingredients to your dough, such as olive oil for added crunch and flavour to a pizza crust, but bear in mind that it will affect the hydration of the dough so adjust the measurements accordingly

Finally - DO NOT flour your work surface and resist all temptation to add any more flour when you're kneading - it'll only mess up the hydration and you won't get the same results if you make the bread again. If the dough ends up being really really sticky then rub some olive oil into your hands and carry on kneading, it'll come together eventually

Finally, here's an improvised example of how you can use this calculation -

725g of strong bread flour - 100%
489ml water - 67.5%
7.2g yeast - 1%
15g salt - 2%
A couple of handfuls of sunflower and pumpkin seeds and a few pinches of caraway seed

Kneading - 10 minutes
First rise - 60 minutes (dough rubbed with olive oil, placed in a bowl, covered and left in a warm place)
Shape bread and proof** - 45 minutes

Bake -
10 minutes at 520F
Reduce temperature to 350F and bake for another 25 minutes
Turn off oven, crack open door and rest for 10 minutes
Place on wire rack and leave to cool completely

Eat.

**Proof simply means rise - you want to get your bread risen by 3/4 before you put it in the oven

The initial very high temperature will give the yeast a very active burst and ensure that you have a full rising loaf, it'll also help to develop crust colour and the final rest will help to thicken the crust

And, well, there you have it! :thumbup1:
 
Nice, I bought some bread making books a few years ago, but never understood the "formula" somehow the way you explain it, it now makes complete sense (and I fancy myself pretty good with numbers), now I can reapproach the book and get me some bread! I can't stand the stuff in the local grocery except for the French baguettes they get from a local bakery...

thanks for the informative post
 
It makes it easier to document and track your hydration rate. 1% can be a big difference!

It can be a little confusing when doing ciabatta or other breads where you squeeze in more water or fat than flour... (brioche) but no need to rush into those.
 
Yeah definitely, brioche and high hydration stuff like ciabatta (85-90% I believe?) is a different game altogether. This was just meant as a rough guide to show that you really don't need to look up a recipe to make bread :thumbup1:
 
If anyone ever needs bread ideas or suggestions, I love going The Fresh Loaf. I would link it but I think that is frowned upon... More formulas and tips than any one person could need.
 
I've been a member there for a little while now, it kinda grates on me how many recipes are measure in cups and oz though :laugh: I think metric is the only way to go when making bread
 
I'll triple-recommend getting a scale. I've been a semi-serious baker for a long time, with lots of good bread made, but once I got a scale things improved amazingly. (And consistency went way up.)

I really like the book "Bread" by Hamelman. Really good. I have lots of others but this one helped me the most. He's a pro writing for pros, with baker's percentage all over the place, but recipes for normal home-scaled amounts of bread are included as well. I make his basic French bread and ciabatta all the time.

The thing about a scale is, a cup of flour can vary immensely in weight depending on how you scoop it, the humidity of your house, etc. Once you get a scale, try to scoop out 3 3/4 C of flour (what is usually given when you want a pound of flour) 5 times, weigh them all, and see how random your results are.

Yes metric is easier, no pounds and odd ounces to convert but when you are brought up on pounds and ounces it gets kind of hard to switch. I prefer all ratios, formulas, recipes, etc to be written in weight- even the liquid measures but I own a scale and know how to use it!

That can be summed up by how you measure your flour. While it sits in the container it is compacted, if you just use the cup to scoop you will compact the flour more making it dense. If you aerate the flour in the container first and then use a scoop and drop the flour easily into the cup then gently cut the excess off the top you will get a consistent measure but you have to do things consistently to get there. But yes humidity and other factors will play a factor.
 
I thought this post needed some pics, so for my 3rd ever loaf of bread (first two followed this recipe, worked out great) i figured I would document.

First off, I tried proofing the yeast this time around, here in the 420ml water at 105*F and 1/2t sugar. This is at 10 minutes (note: I wouldn't do this again. Bread rose too quickly, I think):



While the yeast was proofing, weigh out our dry ingredients. First up is King Arthur's Bread Flour. I posted the nutrition data to get some input on how this compares to "Strong" bread flour.





And a little whole wheat flour from the local bulk foods store (Sprout's) just for a try. Turned out well, would add it in again...



And the salt...

I mixed everything in my Kitchenaid stand mixer on "Slow", the lowest of 10 speeds possible, in order to monitor the dough's consistency and match it with being "sticky", but not unhandle-able. I basically kneaded until I got a "smooth" dough in the bowl without being "silky". This is the part that's going to take some practice to get consistently (hah) better at reading, but the results are well worth the practice. Anyhow...

This is the dough at one minute. Basically mixed together, starting to form a shaggy mess (basically where I feel you would stop "mixing" by hand and start "kneading")



Here is the dough at about 10 minutes (remember, this is "SLOW" speed). Note the dough still sticking to the bowl very well. I added spoonfuls of AP flour at this point every two minutes until the dough came together (4 spoonfuls total).



Here at 20 minutes, when I thought it came together well and was the right consistency (hook lifted for a better view from the experts):



And once I thought it was kneaded to completion (I turned the speed up for this particular shot to show what it would look like on medium speed)



Note that the dough is smoother than the 20 minute mark, but not silky. This is at 30 minutes (remember, SLOW speed here. About the same as 10 mnutes at 4-6 speed on the Kitchenaid). I will let the yeast take care of the rest from this point on.



On to the rising/shaping/baking...

I pulled the dough out with well-EVOO'd hands and plopped it in an oiled pitcher I use for various homebrewing tasks (I love playing with yeast!). Turned the dough a few times to coat and let it rise in a warmed oven (I turned the oven on for 15 seconds to take the chill out of the air):



And 45-55 minutes later, this is what I had:



I punched it down (deflated the airy dough by working it around in the pitcher) and let it rise again:



After the 2nd rise, I floured a large wooden cutting board, removed the dough from the pitcher, and formed a loaf (I didn't have another set of hands to take pictures, and the OL would have KILLED me if I ruined her camera). Here it is on the back of a large sheet pan ready to "proof" under an oiled piece of plastic-wrap (6" scale for reference):



And after proofing. I forgot the scale at this point, but it had almost doubled.



Used the baking directions given by Yetidave above *plus* I preheated a 1.5q saucepan in the oven. After I put the bread in I poureed 1C of water in the pan to "steam" the oven. I've read that this helps crust formation. Turned out well (baked for 35 minutes total, center of loaf was 204*F):





And in the bowl it goes, onto the table to accompany the corn and sausage chow-dah we had for dinner...

 
Bakers percentage is the best. That, a scale, and a simple spreadsheet is the way to go.

If anyone is interested here's my spreadsheet. It probably looks totally confusing, but it isn't.

Cells in blue are figures you enter. Cells in red (i.e. the flour) never change. Cells in green are the output. White cells are just additional info. For you sourdough guys the right side has areas for calculating amount of preferment flour and hydration level of starter. As it is now it's showing a universal sweet dough with commercial yeast.

Thank you for the tip. It makes much more sense now. Would replacing 1/4 to 1/3 whole wheat flour change the % of water used?
 
The depth and breadth of various knowledge on this site is amazing. I came here to be a better shaver, and have turned into a part-time baker, gardener, smoker (grill and otherwise), tailor, etc. etc. Truly awesome stuff here on B&B.

BTW, congrats Yetidave on your recent stewardship. I happened to undertake this on the same day that you posted your new title, quite the coincidence.
 
Thanks Jeremy! That's some great looking bread. I'm still struggling away with a crappy oven but I'm house-sitting for my folks for the next couple of weeks so I'll be taking full advantage of the oven there and hopefully expanding upon this post.

As for farmdog's question, I don't *think* that whole wheat will mess up hydration. What you may find is that the dough becomes stiffer because in general it's not as glutinous. The only flour I've really found that throws a spanner in the works is spelt - you need a whole different set of rules when working with it and I've not got around to figuring it out yet

Oh and that King Arthur flour's got pretty much the same protein content as most strong bread flour (with the exception of Canadian which can be upwards of 14%)
 
Sourdough, entirely from scratch using this formula. It's 100% white flour at 72.5% hydration -

Turns out that a cast iron skillet works pretty well when you've not got access to a baking stone
