Pour the wet ingredients into the dry and stir like a mad person. This is the only tricky part of the recipe.
It will take a bit of stirring to get everything combined. After you've stirred for a minute or two, if it still looks crumbly, you can begin adding water a little at a time. I add about a tablespoon at a time.
You want the dough to be slightly gummy and firm when you're done and look like the third photo. :)
