I know this seems like it should be obvious; calculating bread dough hydration isn't rocket science. My recipe is 600 g of flour, 270 g of water, 57 g of butter, 46 g of honey, 1.5 tsp of salt, 2 tsp of yeast. Salt and yeast are in tsp because at those light weights, there's a significant difference in volume in fractional grams but the idea is 6g of yeast and 7g of salt.

I've read that butter and honey both have about 18% water so I add that to the water and I end up with 48% hydration. Everything I read says this is way too low. The dough in the bread machine seems very moist and is quite sticky. I used a batch for making hamburger buns, using the dough cycle, and it was so sticky and wet I couldn't work with it. But baked in the machine, the bread comes out pretty good, rising to within 1/2 inch of the machine lid and it holds up well to slicing, sandwiches, etc.

So, what gives? Is my calculation wrong or is there some reason I'm succeeding at 48% and, at 48%, the dough is very wet and sticky?

I also make sour dough bread at higher hydration, about 60%, without the breadmaker but it is never as sticky as the bread machine recipe - using the same flour. The flour is Montana All Purpose Flour - a premium flour sold at Walmart.

Is this experience normal or am I doing, measuring, calculating, something wrong?

  • I feel like the fat and sugar from the butter and honey make a bigger difference than the water in each, but I don't know the science, so, just a comment... Jul 15, 2021 at 18:19
  • Why do you think that 48% is too low? What gives you that idea?

Yes, you're calculating it right, it's the flour that makes the difference.

Hydration percent will give you a different result with different flours. Gluten content and grain type and grind (i.e. fine vs course) all influence how much water a dough will absorb. You are using white AP (i.e. plain) flour which has a lower gluten content than bread flour, if you used bread flour or whole wheat instead you'd get a drier dough with the same percentage of hydration.


Hydration is an idea to help you predict the dough consistency/workability based on the ratio of water to flour - but with a highly enriched dough, the effect of the additional ingredients is so strong, that it loses its predictive value. It is also no longer perfectly defined when you have ingredients which make the dough softer without clearly being water/a liquid.

When you calculate the hydration as normal, it is 45% (270/600). It makes no sense to look up the percentages of water in butter and honey and add those, because you didn't add separate water and separate solids; you added one product (actually two here) with its own physical properties, which "acts" as a whole in the dough.

If the low number shocks you, you can try making some kind of creative adjustment, maybe counting all of the honey as a liquid. But really, whatever number you arrive at, you should no expectation that the dough behaves the same way as an unenriched dough of the same hydration. Personally, I would just stop stretching the concept and trying to fit it into situations it is not meant for. You already know how the dough from this recipe feels, there is no need to attach an abstract number to that.

  • I would suggest you could count the water in the honey (a solution) but not in the butter (an emulsion) - but it's rounding error anyway.

  • @ChrisH also, I’d almost suspect that honey would make the dough drier rather than moister. Since the honey could act hygroscopically rather than magically contribute all of its 18% water to the hydration of the flour. Jul 16, 2021 at 16:20

    I disagree that the water in the honey & butter don't count (for example, when making pie crust, the % water in your butter matters a lot), but certainly agree with the rest of your answer.

When making Sourdough I aim for 70% hydration by weight. When using butter, I melt the butter and calculate its weight as 100% liquid, and reduce the water by that amount. This method consistently results in dough with the same workability as when using only flour and water with 70% hydration. I know the butter is not 100% water, but treating it as such works for me.
