Why does my dough always need more water than the recipe calls for? It seems that every dough recipe that I try ends up needing more liquid than the recipe calls for. This applies to pasta dough as well as bread dough. I don't think I've made but one recipe where the ingredients worked out.

Typically, I'm using a recipe from something like a youtube video, so I know what the dough should look like. Theirs might be soft and pliable, where mine "tears" when I try to knead it and won't come together. 

I occasionally have to add flour, but mostly I end up adding water which makes a slimy mess on my hand till it absorbs into the dough. I'd like to get the amount correct from the get go. I know that the amount of required liquid can vary with certain factors, like cooking times varying at different elevations, but it shouldn't be a problem where I live. I'm just tired of trying a recipe and following the directions to the letter, only to find out my dough needs more water.

Am I going to have to deal with this every time I make a dough recipe and write down my adjustments for the next time? Is there enough liquid there and I just need to let it absorb into the flour? What do you think is going on? I do realize that recipes usually need a little tweaking, but I don't run into this consistent problem with any other recipe I make.

EDIT: I live in the South East, USA. One recipe example is the one off of youtube.com from 'America's Test Kitchen' that if for pasta. I can't remember the recipe exactly, I don't even think it calls for water, just eggs and flour, but the issue with too little liquid happens every time I make it. If I can find a bread recipe that calls for water, I've used, I'll post it as well.

Edit: (5/12/2015) I tried to make a recipe I had for Ryan's Rolls. It wanted 1 cup of water and 1/4 cup of honey for the liquid and wanted me to add 3 cups of flour and use the paddle attachment till it came together in a sticky mass, then add an additional 1 cup of flour. I did as instructed, and while it was a sticky mass, I'm not sure it came together in the way they were thinking. I went to add the additional flour and knew it wouldn't take it all, so I added half a cup. It was so dry I took a 1/2 cup of water and added it a little at a time. The dough finally started to do right, but was very tough. I ended up having to stop the kitchen aid a few times and kneed by had to help pull it together. It was easier to work after resting a couple of hours, but my rolls still ended up with weird layers where I was kneading and it wasn't coming together, because it was overly dry and/or tough, and that was leaving out flour and adding almost 1/3rd again the liquid. I also pulled out my scale for this and measured everything by weight to get it exactly right. It's a good example of what I was talking about.
There are at least four likely causes that could be factors:

I'd say the most common problem for your issue is measurement error.  If you aren't measuring flour by weight, it's nearly impossible to be consistent.  And many recipe sources will assume different methods for measuring flour by volume.  You could use the &quot;spoon and level&quot; method where you use a tablespoon or something to gradually add flour loosely to your measuring cup and then level off with a knife or straightedge.  You could use the &quot;scoop and sweep&quot; method where you stick the entire measuring cup into the flour and sweep it against the edge of the bag or bin of flour to level it.  The latter one will pack the flour more and result in more flour per cup.  Or, you might not be leveling the flour at all, or shaking it off until it's roughly level.  You could be packing the flour in tight or scooping it from a tightly settled bag, or you could be using flour that was loose after being poured or even put through a sifter to aerate it further.
In any case, different volume measuring techniques can produce an error of 30% or more in flour measurement, which can make the difference between a dough that's stiff and dry vs. a dough that's so sticky you can't handle it.  Most recipes that use volume measurements assume either a &quot;spoon and level&quot; or &quot;scoop and sweep&quot; method.  If your source doesn't specify, try using a measurement method that won't pack the flour down as much -- which might solve your dry dough problem.

As already mentioned by ElendilTheTall, flours can vary significantly in terms of the amount of water they absorb.  There's the issue of type: high-gluten vs. bread flour vs. &quot;all-purpose&quot; vs. pastry vs. cake.  If you are using a high-protein/high-gluten flour like bread flour but the recipe requests all-purpose, your flour will likely absorb too much water.  Similarly, some brands of flour are made from harder or softer wheats, even they are all termed &quot;all-purpose.&quot;  In the U.S., for example, King Arthur all-purpose will absorb more water than Gold Medal all-purpose, and both will absorb a lot more than &quot;southern&quot; all-purpose flours like White Lily.  Flours in other countries may vary in their processing and content in other ways (ash content, extraction, milling size, etc.).  And even flours from the same company will vary by batch, age, etc.
In general, try using the type of flour recommended by the recipe.  If that isn't working, you might consider a different brand, a &quot;softer flour,&quot; or simply use less.

Kitchen environment can make a big difference, particularly temperature and humidity.  Flour will absorb or lose moisture over time when stored in conditions with changing humidity.  Dough will also absorb or lose moisture at different rates depending on your kitchen conditions.  Thus, even if you measure flour by weight, you can sometimes see significant discrepancies from batch to batch.  If you're using recipes that were designed in a place which was much more humid than your kitchen, it could explain some differences in outcome.

Bad recipes.  It's perhaps obvious, but if you've mostly been using one or two sources for recipes, it's possible that there are consistent errors or problems.  (Or, it's possible that the cookbooks/chefs/sources assume specific measuring techniques, flour types, etc. from what you're using.)


Regardless of what the problem is, if you're noticing a consistent error, then the most obvious solution is to try to quantify how big that error is, and then plan for it.  For example, try reducing your flour measurement in every recipe by 10%, and see what happens.  As you point out, it's often more annoying to add water to a dough than to add flour, so it's better to start out a bit moist and continue adding flour until you get the right texture.
If the error is consistent, and you can always fix it by reducing your amounts by X proportion, you've solved the issue.  The alternative is to consider the various potential causes I mentioned above and see whether you can vary them until you find a solution.
